Abstract
Lithium ion batteries are usually composed of positive electrode,negative electrode,separator and electrolyte.Due to their high specific energy and long cycle life,they are widely used in areas such as 3C digital,power vehicles and energy storage.In the preparation process of lithium-ion batteries,the stability of the positive electrode slurry affects the subsequent processing performance,as well as the electrical properties such as electrode sheets,battery internal resistance,capacity,and cycling.This article summarizes the research progress of dispersion technology for common lithium-ion battery positive electrode slurry,and looks forward to the future development direction of dispersion technology for lithium-ion battery positive electrode slurry.
