PROBLEM TO BE SOLVED: To assemble a lithium secondary battery in a well-workable manner by assembling a negative electrode formed of Li-carried carbon based material stable in the air and a positive electrode formed of positive electrode active material not containing Li in the air. SOLUTION: A positive electrode formed of positive electrode active material not containing Li related to charge and discharge and a negative electrode formed of Li-carried carbon based material stable in the air in a Li-carried state are used to assemble a battery cell in the air. The positive electrode active material is formed by firing V2 O5 , CoCO3 , etc., at 100-500 deg.C. The carbon based material is formed by firing organic polymeric compound such as polyphenine, poly(p-phenylene vinylene), poly(p-phenylene xylene), etc. By using the positive electrode and the negative electrode to assemble the battery cell in the air, a lithium secondary battery is provided in a well-workable manner without requiring large facilities including an inactive atmosphere. |
