Description

一种便于更换电解液的锂电池
技术领域
本发明属于电池电子领域，具体涉及一种便于更换电解液的锂电池。
背景技术
由于锂电池具有放电电压稳定，工作温度范围宽，自放电率低，储存寿命长，无记忆效应，体积小，重量轻及无公害等优点，目前已逐渐替代铅酸蓄电池、镉镍蓄电池，成为动力电池的主流。锂电池内部由电解液这类介质的存在来使得正负离子向负极、正极活动从而产生电流。电解液一般都有使用期限，如果在期限内其他部分完好而电解液不能再使用就比较浪费，如果存在一种能够随时更换电解液的锂电池可以解决这类问题。
发明内容
发明目的：本发明的目的在于针对现有技术的不足，提供一种便于更换电解液的锂电池。
技术方案：为了达到上述发明目的，本发明具体是这样来完成的：一种便于更换电解液的锂电池，包括壳体，所述壳体内底部设有电解液池，且电解液池连接由壳体顶部伸入壳体内的入液通道，所述入液通道由橡胶塞封口；所述正极棒由壳体顶部伸入电解液池内，壳体底部设有负极环。
其中，所述橡胶塞上部覆盖有绝缘层。
其中，有2条入液通道通过壳体内两侧壁伸入电解液池内。
其中，所述绝缘层与壳体之间涂覆有胶水。
有益效果：本发明与传统技术相比，在不增加整个锂电池的体积下，能够完成电解液的更换，进一步提高了锂电池的使用寿命，同时，绝缘层覆盖橡胶塞很好的保护了电池内部的电解液，避免了污染环境。
附图说明
图1为本发明的结构示意图。
