PURPOSE:To highly remove the stuck moisture and improve the charge/discharge reversibility by bringing the polyanine used for a positive electrode into contact with a specific solution to remove the moisture. CONSTITUTION:In a lithium secondary cell using lithium and lithium alloy for a negative electrode and polyanine for a positive electrode, polyanine is brought into contact with propylene carbonyl or the like of a polar organic solution with a large dielectric constant or a mixed solution containing this solution, moisture is removed without deteriorating polyanine. The moisture stuck to polyanine is highly removed, a lithium secondary cell with high charge/ discharge reversibility is manufactured. |
