Title:
SECONDARY BATTERY ELECTRODE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/182090
Kind Code:
A1
Abstract:
The present invention provides a secondary battery electrode composition with which it is possible to manufacture high-performance secondary batteries while suppressing gelation, which exhibits excellent coatability and adhesive properties, and which can achieve both high electron conductivity and dispersibility and dispersion stability of a fibrous carbon material. This secondary battery electrode composition contains an active material, a hydrophilic solvent, a fibrous carbon material, and a polyvinyl acetal resin, and has a water content of 10 wt% or less. The amount of hydroxyl groups in the polyvinyl acetal resin is 30 mol% or less.
