    Abstract: PURPOSE: A secondary battery is provided to additionally introduce a safety improver into a negative electrode, thereby improving safety of a battery at overcharging when internal temperature of the battery is increased at high temperature exposure. CONSTITUTION: A lithium ion secondary battery comprises a negative electrode. The negative electrode comprises a negative electrode layer including a negative electrode active material and a current collector. The negative electrode layer additionally includes alloy represented by chemical formula 1: M_aN_b or /and metal oxides represented by chemical formula 2: Toc. In the chemical formula 1, M is a metal which is not reactable with lithium ions, N is a metal which is reactable with lithium ions, 0

    Abstract translation: 目的:提供二次电池,以将安全性改进剂另外引入负极,从而在高温暴露时电池的内部温度升高时,提高电池的过充电的安全性。 构成:锂离子二次电池包括负极。 负极包括负极层,其包含负极活性物质和集电体。 负极层还包括由化学式1表示的合金:M_aN_b或/和由化学式2表示的金属氧化物:Toc。 在化学式1中,M是不能与锂离子反应的金属,N是与锂离子反应的金属,0
