Stir for 2 hours. Lithium battery slurry production uses 2 hours of stirring to use the principle of slurry shear thinning to reduce the viscosity of the slurry so that the slurry can achieve a higher solid content. A lithium-ion battery is a secondary battery (rechargeable battery) that relies primarily on the movement of lithium ions between positive and negative electrodes to function.
Structural damage, high humidity and high temperature.
1. Structural damage: Alkaline substances present in high nickel cathode materials damage the structure of PVDF.
2. High humidity: The moisture content is too high, especially in the case of high viscosity, and the temperature is too high.
3. High temperature: Excessive temperature of the suspension will cause gelation and the gel state is different from the actual one.gelling state.
