PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery in which electrolyte solution leak is little, and a charging and discharging characteristic is further improved. SOLUTION: A nonaqueous secondary battery is composed of positive electrode active material which is a lithium-containing transition metal compound, a sheet-like positive electrode which has a layer containing positive electrode mixture containing a conduction agent and a binder, negative electrode material which can store and discharge lithium ions, a sheet-like negative electrode which has a layer containing negative electrode mixture containing the conduction agent and the binder, and nonaqueous electrolyte which contains lithium salt. The negative electrode mixture is dispersed in mixed solvent of low boiling point organic solvent whose boiling point is less than 120 deg.C and high boiling point organic solvent whose boiling point is 120 deg.C or more so as to prepare dispersion solution, and the same is applied to a collector, and is dried so as to obtain a negative electrode sheet. |
