Title:
NONAQUEOUS ELECTROLYTIC SECONDARY BATTERY AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JP3642355
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery capable of increasing the filling amount of an active material, enhancing energy density, and improving charge/discharge characteristics by increasing the dispersing capability of positive and negative active materials.
SOLUTION: A nonaqueous electrolytic secondary battery has a negative electrode having a negative mix layer containing a carbonaceous material serving as a negative active material carrying body and a binder resin, a positive electrode containing a positive active material and a binder resin, and a nonaqueous electrolyte. The binder resin is a polyester resin having a reducing viscosity of 0.3dl/g or more, preferably the polyalkylene glycol copolymer polyester resin, and the content of the binder resin in the negative mixture layer is 3-20wt.%.
