Lead to the lithium battery capacity loss would like to have?

Source: 2020 - 03 - All the hits: 30 lithium battery capacity loss is a very complicated process involving a variety of elements. There is no detailed explanation of the working mechanism of each element space, but provides a short list of elements. Lithium battery capacity loss is mainly divided into two parts: calendar aging ( If remove the lithium battery capacity will fall over time) Aging and cycle ( If remove the lithium battery capacity will fall over time) 。 On the former, the main factors involved are as follows: charge state. This is the total capacity. Hypothesis is 40% or 60% temperature; The time to register. On the latter, as follows: the main factors involved in the depth of the discharge at a time. For example, if you are from 0% to 100%, and then you put it in 0%, and then charging, you still use 20% of the battery, charge when you start the prompt, and then you unplug it at 80%, it is not the same thing. Charge state, also called electricity. For the same DoD, unified SoC can be different. For example, in the continuous output 40% 100% circulation, continuous output 20% 80%, while the depth of the charge and discharge the same, but due to the different charging conditions, the impact on the battery is not the same; Charge rate. Assumes that the charging current can be in 1 hours to recharge batteries, the charging ratio of 1 c. Assumes that the charging current within 2 hours full of battery, charging ratio of 0. 5度; And so on; Temperature; The number of cycles. Obviously, a 200 - cycle loss more than 100 cycles. In addition, some factors are we almost can't control. Lithium-ion batteries, for example, in the early stages of its use, will experience solid electrolyte interphase film ( The SEI film) The formation of. This process need to consume a certain amount of lithium ion. The process cannot bypass by battery, so we don't have to think too much.
