[2] 本发明涉及的是电池外壳， 尤其是一种复合结构锂离子电池外壳。
[3]
[4] 锂离子电池是一种具有高倍率放电性能的电池， 是一种
高能量密度电池。 它与同样大小的镍镉电池、 镍氢电池相比， 电量储备最大， 重量最轻、 寿命最长。 因此， 锂离子电池业已成为各种动力设备首选的电池。
[5] 锂离子电池是由一个含锂化合物作为活性材料的正极， 一个以能咐和解吸锂金 属或碳物质的锂材料作为活性材料的负极， 一层能绝缘而又能给电离子导通的 隔离层以及含有六氟磷酸锂 （LiPF6 ) 或高氯酸锂 （LiCI04
) 的非水性电解液及外壳组成。 由于电解液具有很大的腐蚀性， 因此， 锂离子 电池对浸泡在电解液中的正负电极需要配备耐腐蚀性能好的外壳。 目前， 锂离 子电池通常釆用耐腐蚀能力较强的塑质外壳。 塑质锂离子电池外壳虽能满足抗 腐蚀能力， 但存在以下缺陷：
[6] 一、 塑质锂离子电池外壳的强度较低， 容易变形；
[7] 二、 塑质锂离子电池外壳的阻燃性能差， 容易燃烧；
[8] 三、 塑质锂离子电池外壳的撒热效果差；

[20] 所述塑质壳体外壁纵向设有加强筋槽。
[21] 所述金属外壳内壁设有与塑质壳体外壁纵向加强筋槽相吻合的嵌入槽。
[22] 本发明的设计原理是： 在充分发挥塑质材料耐腐蚀性强的基础上， 通过增加金 属外壳来克服单层塑质锂离子电池外壳所存在的缺陷。
[23] 本发明与现有技术相比所具有的有益效果：
[24] 一、 设置在塑质壳体外的金属外壳不仅可提高其抗变形强度， 且可提高电池外 壳的外观。
[25] 二、 金属外壳不会燃烧， 它可有效地防止锂离子电池因外部环境影响而被燃烧 损坏。
[26] 三、 金属外壳具有较强的气密性， 它可弥补塑质壳体气密性差的缺陷， 提高锂 离子电池外壳的密封性。
[27] 四、 利用铝合金材料所具有的极佳热传导性， 可提高锂离子电池工作中的撒热 性， 既有利于锂离子电池的正常使用， 又可延长锂离子电池的使用寿命。
