PROBLEM TO BE SOLVED: To achieve improved productivity. SOLUTION: The method at least comprises an assembling step for fabricating a battery precursor in which a positive electrode 2 and a negative electrode 3, each capable of doping/undoping a lithium ion, and a nonaqueous electrolyte are sealed, and an initial charging step for carrying out the initial charging at an environmental temperature within the range of 30 deg.C-50 deg.C for the battery precursor. |
