SEALED-TYPE SECONDARY BATTERY |
摘要 |
A sealed-type secondary battery is disclosed. A battery module of a sealed-type secondary battery is formed by heating and fusing a top lid member and an integrated battery container. The integrated battery container is formed with a polymer alloy including a polyphenylene ether resin and a polyolefin resin, and the top lid member or a lateral lid member is formed with a polypropylene-based resin. A nucleating agent is added to the polypropylene-based resin of the top lid member or the lateral lid member, to improve mechanical strength, and the molecular weight is increased to reduce a melt flow rate MFR to approximately the same degree as the polymer alloy.
