What are the factors related to the cycle life of lithium batteries?

Cycle life of lithium battery The battery is used, it feels like it is not used, the capacity is not much earlier, these are the manifestations of the declining cycle life. The decay cycle life is actually a correction of the actual available capacity of the battery, which is related to the rated capacity of the battery when it is manufactured. Regarding the aspiring lithium battery, the capacity balance will not change during its cycle. The initial capacity of each cycle should be a specific value, but in reality the situation is much more complicated. Any attack or secondary use of lithium ion may result in a change in battery capacity balance. Once the battery capacity balance changes, this change is irreversible and can be accumulated through repeated cycles, seriously affecting the battery cycle. There are many factors that affect the cycle life of lithium batteries, but the fundamental reason is that the number of lithium ions involved in energy transfer is decreasing. It should be noted that the total amount of lithium in the battery remains unchanged for the time being, but there are few active lithium ions, they are blocked elsewhere or the active channels are blocked, and they cannot calmly participate in the cyclic charge and discharge process. Then, we only need to find out that the reaction that should participate in lithium ion oxidation has recovered, then we can calculate the mechanism of the decline in capacity, and then we can choose a targeted approach to delay the decline in the capacity of lithium batteries and promote the cycle life of lithium batteries.
