What factors will affect the cycle life of ternary lithium batteries?

Factors affecting the cycle life of ternary lithium batteries: 1. The influence of design and manufacturing processes In the process of battery design, the choice of materials is an important factor. The performance characteristics of different materials are different, and there are also gaps in the performance of the batteries developed. The cycle performance of the positive and negative materials is good, and the cycle life of the battery will be long. The manufacturing process of the lithium battery mainly includes: positive and negative electrode ingredients, coating, sheeting, winding, shelling, liquid injection, sealing, chemical forming, etc. In the process of battery processing, the requirements for each step of the process are very strict. Any process that is not well controlled may affect the cycle life performance of the ternary lithium battery. 2. The influence of charge cut-off voltage The amount of delithiation of NMC material is proportional to the charge cut-off voltage, that is to say, the higher the charge cut-off voltage, the greater the delithiation of NMC material, and the correspondingly more unstable the structure of the material. After increasing the cut-off voltage, the capacity of the material is significantly improved, but the rate of material decay is accelerated.
