Title:
BINDER COMPOSITION FOR ELECTRODE OF NONAQUEOUS ELECTROLYTE BATTERY, AND ELECTRODE MIXTURE, ELECTRODE AND BATTERY USING SAME
Document Type and Number:
WIPO Patent Application WO/2004/049475
Kind Code:
A1
Abstract:
A composition comprising at least a functional group-containing vinylidene fluoride polymer and a polar polymer having a hydroxyl group and/or a carbonyl group in the molecule is used as a binder for an electrode (a positive or negative electrode) active material. Consequently, a nonaqueous electrolyte battery can have improved performance stability and improved safety at the time of internal short-circuiting while maintaining a necessary large capacity.
