摘要： The present invention provides a sealed battery having a large capacity by using a thin safety valve device so as to increase a volume of a cell element. The sealed battery has a high safety owing to the thin safety valve device having an elastic valve element comprising an ethylene-propylene elastomer and thermoplastic resin particles dispersed in the ethylene-propylene elastomer. The elastic valve element is produced by mixing thermoplastic resin particles with an ethylene-propylene elastomer material, molding the mixture into a predetermined shape and, at the same time, crosslinking the ethylene-propylene elastomer material.

摘要翻译： 本发明通过使用薄的安全阀装置来提供具有大容量的密封电池，以增加电池元件的体积。 密封电池具有高安全性，因为安全阀装置薄，具有包含乙烯 - 丙烯弹性体的弹性阀元件和分散在乙烯 - 丙烯弹性体中的热塑性树脂颗粒。 弹性阀元件通过将热塑性树脂颗粒与乙烯 - 丙烯弹性体材料混合制成，将混合物成型为预定形状，同时交联乙烯 - 丙烯弹性体材料。
