電池負極端子板との接触を妨げるという問題があった。However, polypropylene has the following drawbacks: 0) Polypropylene has low mechanical strength, especially tensile yield point strength and flexural modulus. When the power generation element of the battery is sealed by caulking, the amount of plastic deformation of the insulating packing is large, making it difficult to maintain good sealing performance. In addition, as batteries become smaller and thinner, the insulation packing that is plastically deformed after the battery is sealed protrudes above the sealing plate that also serves as the negative terminal plate, preventing contact between the terminals of battery-using equipment and the battery negative terminal plate. There was a problem.
