Advantages and Disadvantages Of Ternary Lithium Battery Many people say that the lithium iron phosphate battery should be fully charged, and the ternary lithium battery should be charged to more than 90%. The reason is that the voltage of the lithium battery will increase after it is fully charged, which will affect the activity of the electrolyte and positive and negative materials, resulting in ...

Pole piece coating generally refers to a process in which a uniformly stirred slurry is evenly coated on the current collector, and the organic solvent in the slurry is dried. The effect of coating has an important impact on battery capacity, internal resistance, cycle life and safety. The reasons for wrinkling during the coating process are as follows: 1. First of all, the installation accuracy o...
