COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY FUNCTION LAYERS BASE WITH FUNCTION LAYER FOR NONAQUEOUS SECONDARY BATTERIES METHOD FOR PRODUCING LAMINATE FOR NONAQUEOUS SECONDARY BATTERIES AND NONAQUEOUS SECONDARY BATTERY
Disclosed is a non-aqueous secondary battery capable of forming a functional layer for a non-aqueous secondary battery capable of exhibiting high blocking resistance in a battery member and exhibiting excellent adhesiveness both before and after immersion in an electrolyte solution. And to provide a composition for a layer. The nonaqueous secondary battery functional layer composition of the present invention contains a particulate polymer, and the particulate polymer has a core shell structure having a core portion and a shell portion that partially covers the outer surface of the core portion, , The glass transition temperature is from -50 占 폚 to 60 占 폚, and the electrolytic solution swelling degree is from 5 times to 30 times. The shell portion has a glass transition temperature of 50 占 폚 to 200 占 폚 and an electrolyte swelling degree of more than 1 time 4 times or less.
