Batteries are a kind of energy conversion and storage devices that convert chemical or physical energy into electrical energy through reactions. According to the different energy conversion of the battery, the battery can be divided into a chemical battery and a biological battery. A chemical battery or chemical power source is a device that converts chemical energy into electrical energy. It comprises two electrochemically active electrodes with different components, respectively, composed of positive and negative electrodes. A chemical substance that can provide media conduction is used as an electrolyte. When connected to an external carrier, it delivers electrical energy by converting its internal chemical energy. A physical battery is a device that converts physical energy into electrical energy.

Pagrindinis skirtumas yra tas, kad veiklioji medžiaga skiriasi. Antrinio akumuliatoriaus aktyvioji medžiaga yra grįžtama, o pirminės baterijos aktyvioji medžiaga – ne. Pirminio akumuliatoriaus savaiminis išsikrovimas yra daug mažesnis nei antrinio akumuliatoriaus. Visgi vidinė varža gerokai didesnė nei antrinio akumuliatoriaus, todėl ir apkrova mažesnė. Be to, pagrindinės baterijos specifinė masės ir tūrio talpa yra didesnė nei turimų įkraunamų baterijų.

Ni-MH batteries use Ni oxide as the positive electrode, hydrogen storage metal as the negative electrode, and lye (mainly KOH) as the electrolyte. When the nickel-hydrogen battery is charged: Positive electrode reaction: Ni(OH)2 + OH- → NiOOH + H2O–e- Adverse electrode reaction: M+H2O +e-→ MH+ OH- When the Ni-MH battery is discharged: Positive electrode reaction: NiOOH + H2O + e- → Ni(OH)2 + OH- Negative electrode reaction: MH+ OH- →M+H2O +e-

The main component of the positive electrode of the lithium-ion battery is LiCoO2, and the negative electrode is mainly C. When charging, Positive electrode reaction: LiCoO2 → Li1-xCoO2 + xLi+ + xe- Negative reaction: C + xLi+ + xe- → CLix Total battery reaction: LiCoO2 + C → Li1-xCoO2 + CLix The reverse reaction of the above reaction occurs during discharge.

Commonly used IEC standards for batteries: The standard for nickel-metal hydride batteries is IEC61951-2: 2003; the lithium-ion battery industry generally follows UL or national standards. Commonly used national standards for batteries: The standards for nickel-metal hydride batteries are GB/T15100_1994, GB/T18288_2000; the standards for lithium batteries are GB/T10077_1998, YD/T998_1999, and GB/T18287_2000. In addition, the commonly used standards for batteries also include the Japanese Industrial Standard JIS C on batteries. IEC, the International Electrical Commission (International Electrical Commission), is a worldwide standardization organization composed of electrical committees of various countries. Its purpose is to promote the standardization of the world's electrical and electronic fields. IEC standards are standards formulated by the International Electrotechnical Commission.

Pagrindiniai nikelio-metalo hidrido akumuliatorių komponentai yra teigiamo elektrodo lakštas (nikelio oksidas), neigiamo elektrodo lakštas (vandenilio saugojimo lydinys), elektrolitas (daugiausia KOH), diafragmos popierius, sandarinimo žiedas, teigiamo elektrodo dangtelis, akumuliatoriaus korpusas ir kt.

Pagrindiniai ličio jonų akumuliatorių komponentai yra viršutinis ir apatinis baterijų dangteliai, teigiamo elektrodo lakštas (aktyvioji medžiaga yra ličio kobalto oksidas), separatorius (speciali kompozicinė membrana), neigiamas elektrodas (aktyvioji medžiaga yra anglis), organinis elektrolitas, akumuliatoriaus korpusas. (padalinta į dviejų rūšių plieninį ir aliuminio apvalkalą) ir pan.

Tai reiškia pasipriešinimą, kurį patiria srovė, tekanti per akumuliatorių, kai baterija veikia. Jį sudaro ominė vidinė varža ir poliarizacijos vidinė varža. Didelė akumuliatoriaus vidinė varža sumažins akumuliatoriaus išsikrovimo darbinę įtampą ir sutrumpins išsikrovimo laiką. Vidiniam pasipriešinimui daugiausia įtakos turi akumuliatoriaus medžiaga, gamybos procesas, akumuliatoriaus struktūra ir kiti veiksniai. Tai svarbus parametras matuojant akumuliatoriaus veikimą. Pastaba: Paprastai vidinė varža įkrautoje būsenoje yra standartinė. Norėdami apskaičiuoti vidinę akumuliatoriaus varžą, vietoj multimetro omų diapazone jis turėtų naudoti specialų vidinės varžos matuoklį.

Nominali akumuliatoriaus įtampa reiškia įtampą, kuri rodoma įprasto veikimo metu. Antrinio nikelio-kadmio nikelio-vandenilio akumuliatoriaus vardinė įtampa yra 1.2 V; antrinės ličio baterijos vardinė įtampa yra 3.6 V.

Atviros grandinės įtampa reiškia potencialų skirtumą tarp teigiamo ir neigiamo akumuliatoriaus elektrodų, kai baterija neveikia, tai yra, kai grandinėje neteka srovė. Darbinė įtampa, taip pat žinoma kaip gnybtų įtampa, reiškia potencialų skirtumą tarp teigiamo ir neigiamo akumuliatoriaus polių, kai baterija veikia, tai yra, kai grandinėje yra viršsrovė.

Akumuliatoriaus talpa skirstoma į vardinę galią ir faktinį pajėgumą. Akumuliatoriaus vardinė talpa reiškia sąlygą arba garantijas, kad akumuliatorius tam tikromis iškrovimo sąlygomis turi iškrauti mažiausią elektros energijos kiekį projektuojant ir gaminant audrą. IEC standartas numato, kad nikelio-kadmio ir nikelio-metalo hidrido baterijos kraunamos 0.1C temperatūroje 16 valandų ir iškraunamos 0.2C – 1.0V įtampa esant 20°C±5°C temperatūrai. Akumuliatoriaus vardinė talpa išreiškiama C5. Ličio jonų akumuliatoriai turi būti kraunami 3 valandas esant vidutinei temperatūrai, nuolatinei srovei (1 C) – pastoviai įtampai (4.2 V) kontroliuojant sudėtingas sąlygas, o tada išsikrauti esant 0.2–2.75 V, kai iškraunama elektros energija yra vardinė. Faktinė akumuliatoriaus talpa reiškia tikrąją audros išleidžiamą galią tam tikromis iškrovimo sąlygomis, kuriai daugiausia įtakos turi iškrovos greitis ir temperatūra (taigi, griežtai kalbant, akumuliatoriaus talpa turėtų nurodyti įkrovimo ir iškrovimo sąlygas). Akumuliatoriaus talpos vienetas yra Ah, mAh (1Ah=1000mAh).

Kai įkraunamas akumuliatorius išsikrauna didele srove (pvz., 1C ar didesne), dėl „butelio kaklo efekto“, egzistuojančio vidinėje srovės viršsrovės difuzijos greičiui, akumuliatorius pasiekia gnybtų įtampą, kai talpa nėra visiškai išsikrovusi. , o tada naudoja nedidelę srovę, pvz., 0.2 C gali toliau šalinti iki 1.0 V/vnt (nikelio-kadmio ir nikelio-vandenilio akumuliatorius) ir 3.0 V/vnt. (ličio akumuliatorius), išleista talpa vadinama likutine talpa.

Ni-MH įkraunamų baterijų iškrovimo platforma paprastai nurodo įtampos diapazoną, kuriame akumuliatoriaus darbinė įtampa yra gana stabili, kai ji išsikrauna pagal tam tikrą iškrovimo sistemą. Jo vertė yra susijusi su išleidimo srove. Kuo didesnė srovė, tuo mažesnis svoris. Ličio jonų akumuliatorių iškrovimo platforma paprastai turi sustabdyti įkrovimą, kai įtampa yra 4.2 V, o srovė yra mažesnė nei 0.01 C esant pastoviai įtampai, tada palikti 10 minučių ir iškrauti iki 3.6 V bet kokiu iškrovimo greičiu. srovė. Tai būtinas standartas baterijų kokybei matuoti.

Tarptautinis IEC standartas numato, kad standartinis nikelio-metalo hidrido akumuliatorių įkrovimas ir iškrovimas yra toks: iš pradžių iškraunu akumuliatorių esant 0.2C–1.0V/vnt., po to kraunamas 0.1C temperatūroje 16 valandų, paliekamas 1 valandai ir įdedamas. 0.2–1.0 V/vnt., ty Įkrauti ir iškrauti bateriją.

Impulsiniam įkrovimui paprastai naudojamas įkrovimas ir iškrovimas, nustatant 5 sekundes, o po to atleidžiant 1 sekundei. Jis sumažins didžiąją dalį įkrovimo proceso metu susidarančio deguonies į elektrolitus pagal iškrovos impulsą. Tai ne tik riboja vidinio elektrolito garavimo kiekį, bet ir tos senos baterijos, kurios buvo stipriai poliarizuotos, po 5-10 kartų įkrovus ir iškrovus šiuo įkrovimo būdu palaipsniui atsigaus arba priartės prie pradinės talpos.

Greitasis įkrovimas naudojamas kompensuoti talpos praradimą, kurį sukelia savaiminis akumuliatoriaus išsikrovimas po to, kai jis visiškai įkrautas. Paprastai aukščiau nurodytam tikslui pasiekti naudojamas impulsinės srovės įkrovimas.

Įkrovimo efektyvumas reiškia laipsnį, kuriuo įkrovimo proceso metu akumuliatoriaus sunaudota elektros energija paverčiama chemine energija, kurią akumuliatorius gali sukaupti. Tam daugiausia įtakos turi akumuliatoriaus technologija ir audros darbo aplinkos temperatūra – paprastai kuo aukštesnė aplinkos temperatūra, tuo mažesnis įkrovimo efektyvumas.

Iškrovos efektyvumas reiškia faktinę galią, išleidžiamą į gnybtų įtampą tam tikromis iškrovimo sąlygomis iki vardinės talpos. Tam daugiausia įtakos turi iškrovos greitis, aplinkos temperatūra, vidinė varža ir kiti veiksniai. Paprastai kuo didesnis iškrovimo greitis, tuo didesnis iškrovimo greitis. Kuo mažesnis iškrovimo efektyvumas. Kuo žemesnė temperatūra, tuo mažesnis iškrovimo efektyvumas.

The output power of a battery refers to the ability to output energy per unit time. It is calculated based on the discharge current I and the discharge voltage, P=U*I, the unit is watts. The lower the internal resistance of the battery, the higher the output power. The internal resistance of the battery should be less than the internal resistance of the electrical appliance. Otherwise, the battery itself consumes more power than the electrical appliance, which is uneconomical and may damage the battery.

Self-discharge is also called charge retention capability, which refers to the retention capability of the battery's stored power under certain environmental conditions in an open circuit state. Generally speaking, self-discharge is mainly affected by manufacturing processes, materials, and storage conditions. Self-discharge is one of the main parameters to measure battery performance. Generally speaking, the lower the storage temperature of the battery, the lower the self-discharge rate, but it should also note that the temperature is too low or too high, which may damage the battery and become unusable. After the battery is fully charged and left open for some time, a certain degree of self-discharge is average. The IEC standard stipulates that after fully charged, Ni-MH batteries should be left open for 28 days at a temperature of 20℃±5℃ and humidity of (65±20)%, and the 0.2C discharge capacity will reach 60% of the initial total.

The self-discharge test of lithium battery is: Generally, 24-hour self-discharge is used to test its charge retention capacity quickly. The battery is discharged at 0.2C to 3.0V, constant current. Constant voltage is charged to 4.2V, cut-off current: 10mA, after 15 minutes of storage, discharge at 1C to 3.0 V test its discharge capacity C1, then set the battery with constant current and constant voltage 1C to 4.2V, cut-off current: 10mA, and measure 1C capacity C2 after being left for 24 hours. C2/C1*100% should be more significant than 99%.

The internal resistance in the charged state refers to the internal resistance when the battery is 100% fully charged; the internal resistance in the discharged state refers to the internal resistance after the battery is fully discharged. Generally speaking, the internal resistance in the discharged state is not stable and is too large. The internal resistance in the charged state is more minor, and the resistance value is relatively stable. During the battery's use, only the charged state's internal resistance is of practical significance. In the later period of the battery's help, due to the exhaustion of the electrolyte and the reduction of the activity of internal chemical substances, the battery's internal resistance will increase to varying degrees.

Statinė vidinė varža – tai vidinė akumuliatoriaus varža išsikrovimo metu, o dinaminė vidinė varža – akumuliatoriaus vidinė varža įkrovimo metu.

The IEC stipulates that the standard overcharge test for nickel-metal hydride batteries is: Discharge the battery at 0.2C to 1.0V/piece, and charge it continuously at 0.1C for 48 hours. The battery should have no deformation or leakage. After overcharge, the discharge time from 0.2C to 1.0V should be more than 5 hours.

IEC stipulates that the standard cycle life test of nickel-metal hydride batteries is: After the battery is placed at 0.2C to 1.0V/pc 01) Charge at 0.1C for 16 hours, then discharge at 0.2C for 2 hours and 30 minutes (one cycle) 02) Charge at 0.25C for 3 hours and 10 minutes, and discharge at 0.25C for 2 hours and 20 minutes (2-48 cycles) 03) Charge at 0.25C for 3 hours and 10 minutes, and release to 1.0V at 0.25C (49th cycle) 04) Charge at 0.1C for 16 hours, put it aside for 1 hour, discharge at 0.2C to 1.0V (50th cycle). For nickel-metal hydride batteries, after repeating 400 cycles of 1-4, the 0.2C discharge time should be more significant than 3 hours; for nickel-cadmium batteries, repeating a total of 500 cycles of 1-4, the 0.2C discharge time should be more critical than 3 hours.

Refers to the internal air pressure of the battery, which is caused by the gas generated during the charging and discharging of the sealed battery and is mainly affected by battery materials, manufacturing processes, and battery structure. The main reason for this is that the gas generated by the decomposition of moisture and organic solution inside the battery accumulates. Generally, the internal pressure of the battery is maintained at an average level. In the case of overcharge or over-discharge, the internal pressure of the battery may increase: For example, overcharge, positive electrode: 4OH--4e → 2H2O + O2↑; ① The generated oxygen reacts with the hydrogen precipitated on the negative electrode to produce water 2H2 + O2 → 2H2O ② If the speed of reaction ② is lower than that of reaction ①, the oxygen generated will not be consumed in time, which will cause the internal pressure of the battery to rise.

IEC stipulates that the standard charge retention test for nickel-metal hydride batteries is: After putting the battery at 0.2C to 1.0V, charge it at 0.1C for 16 hours, store it at 20℃±5℃ and humidity of 65%±20%, keep it for 28 days, then discharge it to 1.0V at 0.2C, and Ni-MH batteries should be more than 3 hours. The national standard stipulates that the standard charge retention test for lithium batteries is: (IEC has no relevant standards) the battery is placed at 0.2C to 3.0/piece, and then charged to 4.2V at a constant current and voltage of 1C, with a cut-off wind of 10mA and a temperature of 20 After storing for 28 days at ℃±5℃, discharge it to 2.75V at 0.2C and calculate the discharge capacity. Compared with the battery's nominal capacity, it should be no less than 85% of the initial total.

The high temperature and humidity test of Ni-MH battery are: After the battery is fully charged, store it under constant temperature and humidity conditions for several days, and observe no leakage during storage. The high temperature and high humidity test of lithium battery is: (national standard) Charge the battery with 1C constant current and constant voltage to 4.2V, cut-off current of 10mA, and then put it in a continuous temperature and humidity box at (40±2)℃ and relative humidity of 90%-95% for 48h, then take out the battery in (20 Leave it at ±5)℃ for two h. Observe that the appearance of the battery should be standard. Then discharge to 2.75V at a constant current of 1C, and then perform 1C charging and 1C discharge cycles at (20±5)℃ until the discharge capacity Not less than 85% of the initial total, but the number of cycles is not more than three times.

After the battery is fully charged, put it into the oven and heat up from room temperature at a rate of 5°C/min.After the battery is fully charged, put it into the oven and heat up from room temperature at a rate of 5°C/min. When the oven temperature reaches 130°C, keep it for 30 minutes. The battery should not explode or catch fire. When the oven temperature reaches 130°C, keep it for 30 minutes. The battery should not explode or catch fire.

The temperature cycle experiment contains 27 cycles, and each process consists of the following steps: 01) The battery is changed from average temperature to 66±3℃, placed for 1 hour under the condition of 15±5%, 02) Switch to a temperature of 33±3°C and humidity of 90±5°C for 1 hour, 03) The condition is changed to -40±3℃ and placed for 1 hour 04) Put the battery at 25℃ for 0.5 hours These four steps complete a cycle. After 27 cycles of experiments, the battery should have no leakage, alkali climbing, rust, or other abnormal conditions.

At present, nickel-cadmium, nickel-metal hydride, and lithium-ion rechargeable batteries are widely used in various portable electrical equipment (such as notebook computers, cameras, and mobile phones). Each rechargeable battery has its unique chemical properties. The main difference between nickel-cadmium and nickel-metal hydride batteries is that the energy density of nickel-metal hydride batteries is relatively high. Compared with batteries of the same type, the capacity of Ni-MH batteries is twice that of Ni-Cd batteries. This means that the use of nickel-metal hydride batteries can significantly extend the working time of the equipment when no additional weight is added to the electrical equipment. Another advantage of nickel-metal hydride batteries is that they significantly reduce the "memory effect" problem in cadmium batteries to use nickel-metal hydride batteries more conveniently. Ni-MH batteries are more environmentally friendly than Ni-Cd batteries because there are no toxic heavy metal elements inside. Li-ion has also quickly become a common power source for portable devices. Li-ion can provide the same energy as Ni-MH batteries but can reduce weight by about 35%, suitable for electrical equipment such as cameras and laptops. It is crucial. Li-ion has no "memory effect," The advantages of no toxic substances are also essential factors that make it a common power source. It will significantly reduce the discharge efficiency of Ni-MH batteries at low temperatures. Generally, the charging efficiency will increase with the increase of temperature. However, when the temperature rises above 45°C, the performance of rechargeable battery materials at high temperatures will degrade, and it will significantly shorten the battery's cycle life.

Spartus iškrovimas reiškia greičio santykį tarp iškrovos srovės (A) ir vardinės talpos (A•h) degimo metu. Valandinis iškrovimas reiškia valandas, reikalingas vardinei galiai iškrauti esant tam tikrai išėjimo srovei.

Since the battery in a digital camera has a low temperature, the active material activity is significantly reduced, which may not provide the camera's standard operating current, so outdoor shooting in areas with low temperature, especially. Pay attention to the warmth of the camera or battery.

Įkrovimas -10—45 ℃ Iškrovimas -30—55 ℃

Jei maišysite naujas ir senas skirtingos talpos baterijas arba naudosite jas kartu, gali atsirasti nuotėkis, nulinė įtampa ir pan. Taip yra dėl galios skirtumo įkrovimo proceso metu, dėl kurio kai kurios baterijos įkraunamos per daug. Kai kurios baterijos nėra visiškai įkrautos ir išsikrauna. Įkrautas akumuliatorius nėra visiškai išsikrovęs, o mažos talpos akumuliatorius yra per daug išsikrovęs. Esant tokiam užburtam ratui, akumuliatorius yra pažeistas ir nuteka arba turi žemą (nulinę) įtampą.

Prijungus du išorinius akumuliatoriaus galus prie bet kurio laidininko, sukels išorinį trumpąjį jungimą. Trumpas kursas gali turėti rimtų pasekmių įvairiems akumuliatorių tipams, pvz., pakilti elektrolito temperatūra, padidėti vidinis oro slėgis ir pan. Jei oro slėgis viršija akumuliatoriaus dangtelio atsparumo įtampą, akumuliatorius nutekės. Tokia situacija smarkiai sugadina akumuliatorių. Jei apsauginis vožtuvas sugenda, tai gali net sukelti sprogimą. Todėl nesujunkite baterijos iš išorės trumpojo jungimo.

01) Charging: When choosing a charger, it is best to use a charger with correct charging termination devices (such as anti-overcharge time devices, negative voltage difference (-V) cut-off charging, and anti-overheating induction devices) to avoid shortening the battery life due to overcharging. Generally speaking, slow charging can prolong the service life of the battery better than fast charging. 02) Discharge: a. The depth of discharge is the main factor affecting battery life. The higher the depth of release, the shorter the battery life. In other words, as long as the depth of discharge is reduced, it can significantly extend the battery's service life. Therefore, we should avoid over-discharging the battery to a very low voltage. b. When the battery is discharged at a high temperature, it will shorten its service life. c. If the designed electronic equipment cannot completely stop all current, if the equipment is left unused for a long time without taking out the battery, the residual current will sometimes cause the battery to be excessively consumed, causing the storm to over-discharge. d. When using batteries with different capacities, chemical structures, or different charge levels, as well as batteries of various old and new types, the batteries will discharge too much and even cause reverse polarity charging. 03) Storage: If the battery is stored at a high temperature for a long time, it will attenuate its electrode activity and shorten its service life.

Jei jis ilgą laiką nenaudos elektros prietaiso, geriausia išimti bateriją ir įdėti į žemos temperatūros, sausą vietą. Jei ne, net ir išjungus elektros prietaisą, sistema vis tiek sumažins akumuliatoriaus srovę, o tai sutrumpins audros tarnavimo laiką.

According to the IEC standard, it should store the battery at a temperature of 20℃±5℃ and humidity of (65±20)%. Generally speaking, the higher the storage temperature of the storm, the lower the remaining rate of capacity, and vice versa, the best place to store the battery when the refrigerator temperature is 0℃-10℃, especially for primary batteries. Even if the secondary battery loses its capacity after storage, it can be recovered as long as it is recharged and discharged several times. In theory, there is always energy loss when the battery is stored. The inherent electrochemical structure of the battery determines that the battery capacity is inevitably lost, mainly due to self-discharge. Usually, the self-discharge size is related to the solubility of the positive electrode material in the electrolyte and its instability (accessible to self-decompose) after being heated. The self-discharge of rechargeable batteries is much higher than that of primary batteries. If you want to store the battery for a long time, it is best to put it in a dry and low-temperature environment and keep the remaining battery power at about 40%. Of course, it is best to take out the battery once a month to ensure the excellent storage condition of the storm, but not to completely drain the battery and damage the battery.

A battery that is internationally prescribed as a standard for measuring potential (potential). It was invented by American electrical engineer E. Weston in 1892, so it is also called Weston battery. The positive electrode of the standard battery is the mercury sulfate electrode, the negative electrode is cadmium amalgam metal (containing 10% or 12.5% kadmis), o elektrolitas yra rūgštus, prisotintas kadmio sulfato vandeninis tirpalas, kuris yra sotusis kadmio sulfatas ir gyvsidabrio sulfato vandeninis tirpalas.

01) External short circuit or overcharge or reverse charge of the battery (forced over-discharge); 02) The battery is continuously overcharged by high-rate and high-current, which causes the battery core to expand, and the positive and negative electrodes are directly contacted and short-circuited; 03) The battery is short-circuited or slightly short-circuited. For example, improper placement of the positive and negative poles causes the pole piece to contact the short circuit, positive electrode contact, etc.

01) Whether a single battery has zero voltage; 02) The plug is short-circuited or disconnected, and the connection to the plug is not good; 03) Desoldering and virtual welding of lead wire and battery; 04) The internal connection of the battery is incorrect, and the connection sheet and the battery are leaked, soldered, and unsoldered, etc.; 05) The electronic components inside the battery are incorrectly connected and damaged.

To prevent the battery from being overcharged, it is necessary to control the charging endpoint. When the battery is complete, there will be some unique information that it can use to judge whether the charging has reached the endpoint. Generally, there are the following six methods to prevent the battery from being overcharged: 01) Peak voltage control: Determine the end of charging by detecting the peak voltage of the battery; 02) dT/DT control: Determine the end of charging by detecting the peak temperature change rate of the battery; 03) △T control: When the battery is fully charged, the difference between the temperature and the ambient temperature will reach the maximum; 04) -△V control: When the battery is fully charged and reaches a peak voltage, the voltage will drop by a particular value; 05) Timing control: control the endpoint of charging by setting a specific charging time, generally set the time required to charge 130% of the nominal capacity to handle;

01) Zero-voltage battery or zero-voltage battery in the battery pack; 02) The battery pack is disconnected, the internal electronic components and the protection circuit is abnormal; 03) The charging equipment is faulty, and there is no output current; 04) External factors cause the charging efficiency to be too low (such as extremely low or extremely high temperature).
