PROBLEM TO BE SOLVED: To cause no energy density decrease, make no need of lithium storing process before battery assembly, avoid taking a long time for manufacture, and make usable immediate after battery assembly in the case a non aqueous electrolytic secondary battery comprising a cathode containing lithium, an anode of a carbonaceous material, and a non-aqueous electrolytic liquid is manufactured. SOLUTION: A lithium storing process carried out by immersing and passing the anode 2 in and through a solution produced by dissolving lithium in a solvent and then evaporating the solvent is employed as a prior process to a rolling process to spirally roll a cathode 1, an anode 2, and a separator 3 sandwiched between these electrodes. Consequently, lithium is stored in the carbonaceous material of the anode 2 and lithium equivalent to irreversible capacity caused in the anode 2 can be supplemented. |
