Title:
ELECTRICALLY CONDUCTIVE MATERIAL PASTE FOR NONAQUEOUS SECONDARY BATTERY, SLURRY FOR NONAQUEOUS SECONDARY BATTERY NEGATIVE ELECTRODE, NEGATIVE ELECTRODE FOR NONAQUEOUS SECONDARY BATTERY, AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/053926
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrically conductive material paste for a nonaqueous secondary battery, with which it is possible to form an electrode that exhibits suppressed dust fall and that enables the nonaqueous secondary battery to exhibit excellent cycle characteristics. An electrically conductive material paste according to the present invention contains carbon nanotubes, a dispersing agent, and water. The dispersing agent contains a water-soluble polymer that contains a conjugated diene monomer unit and a carboxylic acid group-containing monomer unit.
