What will affect the service life of lithium batteries

What will affect the service life of lithium batteries? Aspect 1: The deep correlation between charging and discharging and battery charging frequency. From the data and information obtained from the experiment, it can be seen that the battery charging frequency of the rechargeable battery is deeply related to the battery charging. The more deeply the battery is charged, the lower the charging frequency of the rechargeable battery. Filling frequency * charge and discharge depth u003d fill the frequency within the total cycle time, the more frequent the fill cycle time, the more the fill frequency * charge and discharge depth u003d detailed service life of the rechargeable battery (ignoring other elements) aspect 2: overcharge, Loss of electricity, and the large amount of battery charging current. Rechargeable batteries are not allowed to cause overcharging. All overcharging methods of lithium batteries will cause serious damage to battery performance and even lower characteristics. Do not charge and discharge below 2V or deep, because that will quickly destroy the lithium battery. The internal metal material plating is very likely to occur, which will cause short-circuit failure, resulting in unusable or unsafe rechargeable batteries. Most lithium batteries have an electronic circuit inside the rechargeable battery. When the battery is charged or discharged, when the battery voltage is less than, exceeds, or when the current of the rechargeable battery exceeds the predetermined threshold, the power circuit will disconnect the rechargeable battery. . It is not necessary to use a large current to charge and discharge the battery, because the large current will cause excessive working pressure on the rechargeable battery. Aspect 3: The natural environment is over-temperature or low-temperature. The lifespan of lithium batteries is also greatly affected by temperature. When the electronic product is started, the natural environment with a temperature below zero may damage the lithium battery, while the over-temperature natural environment will reduce the volume of the rechargeable battery. Therefore, if the rechargeable battery is not removed from the external power supply of the notebook computer for a long time, the rechargeable battery will be in the high heat discharged from the notebook for a long time and will be quickly eliminated. Aspect 4: Long-term full power and no power. Lithium battery power is too high or too low will endanger the number of battery cycles. The repetitive battery charging frequency marked on most household appliances or rechargeable batteries sold in the market is based on 80% charging and discharging as the standard test. The test shows that for some laptop lithium batteries, the working voltage of the rechargeable battery will often exceed the specified working voltage ampere, that is, the service life of the rechargeable battery will decrease if the ampere is increased to the ampere, and the service life will be reduced if the ampere is increased 1/3; The greater the charge, the greater the depletion of the rechargeable battery. Long-term low or no electricity will cause the internal frictional resistance of the rechargeable battery to the electronic devices to become greater and greater, which will cause the battery power to shrink.
