Abstract

本实用新型公开了一种锂电池外壳，旨在提供一种在电池内部压力增大的情况下，不会产生爆炸危险，提高锂电池的使用寿命和安全性的锂电池外壳。由壳体和底板连接而成，所述底板的中心向内凹陷并由中心向外部圆滑过渡。所述底板中心部位与最外部边缘部位的高度差为1mm。本实用新型的锂电池外壳底板向内凹陷，在电池内部压力增大的情况下，逐渐变成平面状态，不会向外凸出，避免发生爆炸危险，提高了电池的使用寿命和安全性。

Description

锂电池外壳
技术领域
本实用新型涉及一种锂电池外壳。
背景技术
锂电池由于比能量高，使用寿命长，而得到广泛应用。
目前的锂电池外壳由壳体和底板连接而成，底板为平面结构，在电池内部压力增大的情况下，底板会向外凸出，使其变形、爆裂，甚至会爆炸，影响电池的使用寿命。而且，危害人身安全。
实用新型内容
本实用新型是为了克服现有技术中的不足之处，提供一种在电池内部压力增大的情况下，不会产生爆炸危险，提高锂电池的使用寿命和安全性的锂电池外壳。
本实用新型通过下述技术方案实现：
一种锂电池外壳，由壳体和底板连接而成，其特征在于，所述底板的中心向内凹陷并由中心向外部圆滑过渡。
所述底板中心部位与最外部边缘部位的高度差为1mm左右。
本实用新型具有下述技术效果：
本实用新型的锂电池外壳底板向内凹陷，在电池内部压力增大的情况下，逐渐变成平面状态，不会向外凸出，避免发生爆炸危险，提高了电池的使用寿命和安全性。
附图说明
图1为本实用新型锂电池外壳的示意图。
具体实施方式
以下结合附图和具体实施例对本实用新型进行详细说明。
图1为本实用新型锂电池外壳的示意图，由壳体和底板连接而成，所述底板的中心向内凹陷并由中心向外部圆滑过渡。
所述底板中心部位与最外部边缘部位的高度差为1mm左右。
本实用新型的锂电池外壳底板向内凹陷，提高了电池的使用寿命和安全性。

Claims (2)
