BINDER FOR SECONDARY BATTER ELECTRODE, AND ELECTRODE FOR SECONDARY BATTERY AND NONAQUEOUS ELECTROLYTIC SOLUTION SECONDARY BATTERY USING THE BINDER

摘要

PROBLEM TO BE SOLVED: To provide a binder for a secondary battery electrode superior in binding property, and capable of contributing to output improvement of a battery, an electrode for the secondary battery and a nonaqueous electrolytic solution secondary battery using the binder.

SOLUTION: The binder for the secondary battery electrode has a water soluble polymer neutralized salt, of a copolymer of methyl vinyl ether and maleic anhydride, as a main component. In the water soluble polymer neutralized salt, out of constituting metal ions, it is preferable that the content of lithium ions is 50 mol% or more and that the content of sodium ions is 3 mol% or more.
