PURPOSE:To obtain a battery that facilitates the handling of a power generating element and can respond to long-term reliability by making a hot melt adhesive agent film adhere to the surface of lithium or its alloy. CONSTITUTION:Lithium and its alloy are prevented from making contact to oxygen, nitrogen, water, carbon dioxide, etc. by covering the surface of lithium or its alloy with a hot melt adhesive film. Heat sealing resin films, such as polyethylene, propylene, polyester, nylon, and ionomer, are used as the hot melt adhesive agent films, but the fusion temperature of these hot melt adhesive agent films must be lower than the fusion point of lithium and its alloy. |
