With the development of science and technology, the lithium battery market is getting wider and wider. In order not to affect the service life of the lithium battery, you need to know some precautions about the use of the lithium battery, so as to avoid the wrong use method and reduce the service life of the lithium battery. Next, lithium battery technical trainers will briefly talk about the factors that affect the service life of lithium batteries.
1. The relationship between the depth of charge and discharge and the frequency of battery charging.
It can be seen from the data information obtained from the experiment that the battery charging frequency of the rechargeable battery is related to the battery charging depth. The heavier the battery charging depth, the less the charging frequency of the rechargeable battery. Filling frequency * deep charge and discharge = frequency of filling in the total cycle time, the more the frequency of filling in the total cycle time, the more filling frequency * deep charge and discharge = specific service life of the rechargeable battery (ignoring other factors)
2. Overcharging, power loss, and large battery charging current.
Do not allow overcharging of rechargeable batteries. Any overcharging method of lithium batteries will cause serious damage to battery performance, and even cause performance degradation. Do not charge and discharge below 2V or deep, as that will quickly destroy the lithium battery. Internal metal plating is likely to occur, resulting in a short circuit failure, making the rechargeable battery unusable or unsafe.
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 a predetermined threshold, this power circuit will disconnect the rechargeable battery connection. . It is not necessary to charge and discharge the battery with high current, because the high current will cause excessive working pressure to the rechargeable battery.
3. The natural environment is over-temperature or low-temperature.
Lithium battery life is also greatly affected by temperature. When electronic products are started, the natural environment with temperature below minus zero may damage the lithium battery, while the natural environment with over-temperature will reduce the capacity of the rechargeable battery. Therefore, if the notebook computer uses an external power supply for a long time without taking out the rechargeable battery, the rechargeable battery will be in the high heat discharged from the notebook for a long time and will be quickly eliminated.
4. Long-term full grid electricity, no electricity situation.
Lithium-ion batteries with too high or too low charge will jeopardize battery cycle times. Most of the rechargeable batteries marked on household appliances or rechargeable batteries in the market are subject to 80% charge and discharge as the standard test. Experiments show that for some notebook lithium batteries, the working voltage of the rechargeable battery often exceeds the standard working voltage ampere, that is, from ampere to ampere, the service life of the rechargeable battery will decrease, and then increase the amperage, the service life will decrease. 1/3; The greater the charge, the greater the consumption of the rechargeable battery. Long-term low or no power conditions will increase the frictional resistance of the rechargeable battery to the electronic devices, thereby reducing the battery power.
