<P>PROBLEM TO BE SOLVED: To provide a binder for aqueous system electrode composition enabling realization of an aqueous system cathode composition forming a cathode fully exerting performance as one for a nonaqueous secondary battery, while containing as an active material lithium salt which is considered as difficult for use in an aqueous system, and is capable of suitably being used as an anode composition. <P>SOLUTION: The binder used for the aqueous system electrode composition forming an electrode for a nonaqueous secondary battery contains a polymer, having a structural unit (I) originated from an unsaturated polyalkylene glycol ether system monomer (a). <P>COPYRIGHT: (C)2011,JPO&INPIT |
