    • Provision of an extension-type battery pack which is improved in safety thereof against dropping and impact application. Although a battery pack is susceptible to damage caused by an impact since partial battery cells are located outside the outline of a notebook PC when it is mounted on the notebook PC, the battery pack is provided with a partition wall structure including an air space and a fireproof wall formed of a material which does not melt at a temperature of combustible gas discharged from a gas discharge valve of the respective battery cells. The material of the fireproof wall is preferably mica or the like. The partition wall structure can be provided between an inside battery compartment and an outside battery compartment of the battery pack or can be provided among other battery cells. This prevents fire spreading to other battery cells even if high-temperature combustible gas is discharged from a battery cell damaged by an impact or the like.
    • 提供延长型电池组,其在安全性方面得到改进以防止落下和冲击应用。 虽然电池组由于部分电池单元被安装在笔记本电脑上而位于笔记本电脑的轮廓外部时容易受到冲击所造成的损害,但电池组具有分隔壁结构,该分隔壁结构包括空气空间和 防火墙由在各个电池单元的排气阀排出的可燃气体的温度下不熔化的材料形成。 防火墙的材质优选为云母等。 分隔壁结构可以设置在电池组的内部电池室和外部电池室之间,或者可以设置在其他电池单元之间。 即使高温可燃性气体从受冲击等损坏的电池单体排出,也能够防止其他电池单元的火焰蔓延。
