Which ones are willing to cause the capacity loss of lithium batteries?

The capacity loss of lithium batteries is an extremely complex process involving multiple elements. There is no room to explain in detail how each element works, but a short list of elements is provided. Lithium battery capacity loss is mainly divided into two parts: calendar aging (if the lithium battery is removed, the capacity will decrease with time) and cyclic aging (if the lithium battery is removed, the capacity will decrease with time). Regarding the former, the important factors involved are as follows: State of charge. This is the total capacity. Suppose it is 40% or 60% temperature; it's time to register. Regarding the latter, the important factors involved are as follows: The depth of each discharge. For example, if you go from 0% to 100%, and then you put it into 0%, and then charge, you still use 20% of the battery, you start charging when prompted, and then you unplug it at 80%, This is not the same thing; the state of charge, also known as electricity. Regarding the same DoD, the unified SoC can be different. For example, in a continuous power cycle of 40%-100% and a continuous power of 20%-80%, although the depth of charge and discharge is the same, the impact on the battery is different due to different charging conditions; the charging rate. Assuming that the charging current can charge the battery within 1 hour, the charging ratio is uniform 1C. Assuming that the charging current is full of the battery within 2 hours, the charging ratio is 0.5c; etc.; temperature; number of cycles. Obviously, 200 cycles have a greater loss than 100 cycles. In addition, some factors are almost beyond our control. Taking a lithium battery as an example, in the early stage of its use, it will experience the formation of a solid electrolyte phase interface film (SEI film). This process consumes a certain amount of lithium ions. This process cannot be bypassed through the use of batteries, so we don't have to think too much.
