What is the cause of the lithium battery capacity degradation
Lithium ion motive battery as an electric forklift power source , determines how long the forklift could work after fully charged. But in the actual use process, due to the influence of various factors, the battery capacity decline. This is like our electronic products, after using a long time , you will find that the performance is not as good as before, and the using time is not as good as before too. when we taking about the cause of lithium battery decline, we need to look from the working conditions of lithium battery.
Currently, Forklift lithium battery mainly made of lithium iron phosphate , So for lithium iron phosphate, The biggest d is working in high temperature condition. This will affect its service life.
Of course, This also affects the energy density. From the work condition of the forklift, The resulting battery capacity degeration is mainly due to different charging and discharge rate to meet different driving conditions in working field . The greater the charge and discharge rate, The faster the battery capacity decay. In fact, the structure and nature of the material lof the lithium batteries will change in high charge and discharge rate, that Makes it's difficult to diffuse the internal ion.
For the battery, if the internal resistance is inconsistent, it will lead to internal current and voltage deviating,so one cell or several cells 's volt will lower then others. it will affect the power battery life.
Actually , various factors are affecting each other. So far, the lithium ion motive battery capacity degeration is inevitable. But with the continuous improvement of power battery technology, we will solve the problem of battery capacity decline to extend the service life of power battery is very important.
