Polyvinylpyrrolidone (PVP) is a non-ionic polymer polymerized by N-vinyl pyrrolidone (NVP) under certain conditions. PVP can be used as a dispersant for lithium- ion battery electrodes and a processing aid for conductive materials. Data show that in the field of new energy batteries, the amount of 1GWh PVP is about 15 tons, mainly using industrial grade PVPK30. This paper describes in detail how PVP is used as a dispersant in lithium-ion battery and the market demand of PVP in lithium-ion battery industry. PVP dispersant for lithium battery cathode material Slurry is very important in the production of lithium-ion batteries. The quality of the battery is 70% related to the quality of the pole sheet, and the quality of the pole sheet is 70% related to the quality of the slurry. The production of slurry is equivalent to the completion of 50% of the battery, which is the core work of…
