BINDER RESIN COMPOSITION FOR BATTERY, MIX SLURRY, ELECTRODE AND BATTERY USING RESIN CONTAINING CARBOXYL GROUP

摘要

PROBLEM TO BE SOLVED: To provide a binder resin composition for a battery having flexibility and electrolyte liquid resistant property; a mixture slurry containing the above composition; an electrode excellent in electrolyte liquid resistant property and flexibility using the above mixture slurry; the battery using the above electrode; and a usage of the carboxyl group containing resin excellent in flexibility and electrolyte resistant property as a binder for a battery.

SOLUTION: The binder resin containing the carboxyl group-containing resinprepared by copolymerizing an acrylic acid and/or an methacrylic acid of 10-95 pts. mass, and a monomeric substance of 1-50 pts. mass, expressed in the general formula (1) is used as the binder resin composition for the battery. The mixture slurry including the composition; the electrode having excellent electrolyte resistant property and flexibility using the above mixture slurry; and the battery using the electrode are provided. In the formula (1), R1is H or CH3, and R2is a carbon hydride group of 5-30C.
