NEGATIVE ELECTRODE FOR NONAQUEOUS SECONDARY BATTERIES, NONAQUEOUS SECONDARY BATTERY, NONAQUEOUS SECONDARY BATTERY SYSTEM, AND METHOD FOR MANUFACTURING NONAQUEOUS SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide: a nonaqueous secondary battery which exhibits satisfactory charge and discharge cycle characteristics even if it is charged with a high final voltage; a negative electrode for forming such a nonaqueous secondary battery; a system arranged by use of such a nonaqueous secondary battery; and a method for manufacturing such a nonaqueous secondary battery.SOLUTION: A nonaqueous secondary battery of the present invention comprises: a positive electrode; a negative electrode; a separator; and a nonaqueous electrolyte. The nonaqueous secondary battery is arranged to meet the following requirements (1) and (2): (1) the positive electrode has a positive electrode mixture layer including at least, a positive electrode active material, a resin (A) including a hydrophilic functional group, and a binder resin other than the resin (A); in the positive electrode mixture layer, the content of the resin (A) is 0.01-0.75 pt.mass to 100 pts.mass of the positive electrode active material; or (2) the negative electrode has, on at least a part of its surface, a resin (A) having a hydrophilic functional group or a fibrous material including a modification of the resin (A).
