Title:
SLURRY COMPOSITION FOR NEGATIVE ELECTRODES FOR SECONDARY BATTERIES
Document Type and Number:
WIPO Patent Application WO/2024/095759
Kind Code:
A1
Abstract:
The present invention provides a slurry composition for negative electrodes for secondary batteries, the slurry composition using carbon nanotubes and still exhibiting high stability and being capable of forming a negative electrode that has a low resistance value if formed into an electrode, thereby being suitable for the production of a battery electrode for a lithium ion battery or the like. A slurry composition for negative electrodes for secondary batteries according to the present disclosure contains at least carbon nanotubes, a conductive material, an active material for negative electrodes, a dispersant and a binder component, and is characterized in that the dispersant is composed of a carboxymethyl cellulose having a mass average molecular weight of 300,000 or less or a metal salt thereof, and a carboxymethyl cellulose having a mass average molecular weight of 1,000,000 to 3,000,000 or a metal salt thereof.
