Title:
METHOD FOR PRODUCING SLURRY FOR NONAQUEOUS BATTERY ELECTRODES
Document Type and Number:
WIPO Patent Application WO/2019/107187
Kind Code:
A1
Abstract:
Provided is a method for producing a slurry for nonaqueous battery electrodes, the method providing good dispersibility of a conductive auxiliary agent and being capable of reducing the internal resistance as a battery while ensuring sufficient bindability between active materials and between the active materials and the current collector in a nonaqueous battery electrode. Also provided are a method for producing a nonaqueous battery and a method for producing a nonaqueous battery. The method for producing a slurry for nonaqueous battery electrodes, the slurry comprising a binder composition that contains an aqueous medium and a binder for nonaqueous battery electrodes, a conductive auxiliary agent, and an active material, comprises: a dispersion step for dispersing the conductive auxiliary agent in the binder composition; and a mixing step for mixing the conductive auxiliary agent-containing binder composition obtained in the dispersion step and the active material.
