Preparation, Process Optimization and Performance of LiNi1/3Mn1/3Co1/3O2 Coin‐Type Lithium Ion Battery

In this paper, in order to optimize process and improve the performance of LiNi1/3Mn1/3Co1/3O2 coin-type lithium ion battery, the significantly influential factors were screened by orthogonal test. The technological conditions such as acetylene black%, PVDF%, drying temperature and drying time were investigated. The main experiment target include capacity retention rate at 0.2C and 1C. The optimal technological condition combination of LiNi1/3Mn1/3Co1/3O2 coin-type lithium ion battery was obtained by orthogonal analysis.
