ELECTRODE FOR SECONDARY BATTERY, BINDER FOR SECONDARY BATTERY ELECTRODE, AND SECONDARY BATTERY

摘要

Disclosed is an electrode for a secondary battery, which is used in a lithium ion secondary battery or the like and has further improved high-temperature characteristics and long-term cycle characteristics. Specifically disclosed is an electrode for a secondary battery, which is obtained by laminating an electrode active material layer on a collector, said electrode active material layer containing a block copolymer that contains no halogen atom and has a main chain that contains no unsaturated bond. Also specifically disclosed is a secondary battery comprising a positive electrode, an electrolyte solution, a separator and a negative electrode, wherein the positive electrode and/or the negative electrode is the above-described electrode for a secondary battery. It is preferable that the block copolymer is configured of a segment that has compatibility with the electrolyte solution and a segment that does not have compatibility with the electrolyte solution.
