What is the Typical Life Span of a Lithium Battery?
2022-03-10
Many of the batteries used in everyday items in life are lithium batteries, lithium batteries are divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain the state of lithium metal, and is rechargeable. The life of lithium batteries is "500 times", many friends in order to extend the life of the battery, each time the battery is completely depleted and then recharged, which really has an extended effect on the life of the battery? The answer is no.
The life of a lithium battery is "500 times", referring not to the number of charges, but a charge and discharge cycle. A lithium battery is only half charged on the first day, and then fully charged for it. If it is still like this on the second day, it is with half of the power, a total of two charges down, which can only be counted as one charging cycle, not two. Every time a charging cycle is completed, the capacity of the battery will be reduced a little. We can also understand it this way: the life of lithium batteries and the total charging power of the battery, as well as the number of charges is not related. The effect of deep discharge and shallow discharge on the life of Li-ion battery is not very different.
In fact, shallow discharge and shallow charging are more beneficial to LiPo. Deep discharge and deep charging are only necessary when the power module of the product is calibrated to LiPo. Therefore, the use of lithium-ion products do not have to be bound to the process, everything to the convenience of the first, recharge at any time, do not have to worry about affecting the life. In order to maximize the effectiveness of the lithium-ion battery, it needs to be used frequently so that the electrons in the lithium battery are always in a state of flow. If you don't use your lithium-ion battery often, be sure to remember to complete a charge cycle once a month to calibrate the lithium-ion battery for power, i.e., deep discharge and deep charge once a month.
The "charge/discharge cycle" is not equal to the "charge count", the cycle is the battery from full to used up, which is a cycle, if your battery from a full state, used a tenth of the power, and then full, which is a tenth of the cycle, so charge 10 times, only basically count as a cycle. From a fully charged state, used half and then full, then half and then full again, this is also a cycle, at which point you have to charge it twice. Therefore, the cycle only depends on "how much power is discharged from the battery cumulatively" and is not directly related to the "number of charges".
There is no fixed limit on the number of times to charge a lithium battery, and batteries produced by regular manufacturers can generally be charged and discharged at least 500 times, and the capacity remains at more than 80% of the initial capacity, and a day of charging can be used for 2 years. Usually cell phone battery charging 1000 times, the battery will be seriously not durable. However, high-quality batteries will still retain 80% of the original capacity after many recharges, and many lithium-ion products are still used as usual after two or three years.
