COMPOSITION FOR ELECTRODE OF NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, ELECTRODE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY USING THE SAME, AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide: a composition for electrodes of a nonaqueous electrolyte secondary battery, which can produce the electrodes with high adhesive strength between a collector and an active material layer and also with excellent flexibility; electrodes for the nonaqueous electrolyte secondary battery using the same; and the nonaqueous electrolyte secondary battery.

SOLUTION: The composition for electrodes of nonaqueous electrolyte secondary battery including active materials and binder resin is characterized by comprising vinyl pyrrolidone-based polymer as a binder resin, and a hydroxyl group equivalent of the vinyl pyrrolidone-based polymer stays within a range of 250-2,500.
