BINDER FOR HEAT-RESISTANT PROTECTIVE LAYER OF SECONDARY BATTERY, AND COMPOSITION FOR HEAT-RESISTANT PROTECTIVE LAYER

摘要

PROBLEM TO BE SOLVED: To provide a heat-resistant protective layer of a secondary battery superior in a short circuit prevention effect by including a binder for a heat-resistant protective layer of a secondary battery having excellent binding force to a filler or an active material layer and excellent in electrolyte solution resistance to possess strong binding ability.

SOLUTION: In the binder for the heat-resistant protective layer of the secondary battery and the composition for the heat-resistant protective layer, the heat-resistant protective layer of the secondary battery including the filler and the binder is composed of a carboxylated diene-based polymer latex.
