Lithium ion battery positive electrode slurry, positive electrode plate and lithium ion battery
The present invention relates to a lithium ion battery positive electrode slurry, a positive plate and a lithium ion battery, the lithium ion battery positive electrode slurry comprises an active material, a binder and a conductive agent, the conductive agent is a CNT conductive adhesive subjected to sanding treatment until the viscosity is 0.1-0.5 million mPa.s, and the CNT conductive adhesive comprises, by mass, 4% of CNT, 95% of N-methyl pyrrolidone, and 1% of a dispersant. According to the lithium ion battery positive electrode slurry, on the basis that the requirements of low viscosity, uniform dispersion, high solid content and stability are met, the cost does not need to be additionally increased, other impurities do not need to be introduced into a battery, and the battery performance cannot be influenced..
