COIN TYPE LITHIUM PRIMARY BATTERY AND MANUFACTURING METHOD OF POSITIVE ELECTRODE FOR COIN TYPE LITHIUM PRIMARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a coin type lithium primary battery having high discharge characteristics by decreasing contact resistance between a positive electrode and a battery case in the coin type lithium primary battery including a positive electrode, a negative electrode made of a lithium metal, and a nonaqueous electrolyte. SOLUTION: The coin type lithium primary battery having high discharge characteristics can be obtained by arranging the positive electrode inside the battery case, the positive electrode being blanked from the expand metal core material side filled with the positive electrode.
