Description

带安全保护装置的柱状锂电池
技术领域
本实用新型设计一种锂电池,具体涉及一种带安全保护装置的柱状锂电池。
背景技术
锂离子电池是一种充电电池,它主要依靠锂离子在正极和负极之间移动来工作。在充放电过程中,Li+在两个电极之间往返嵌入和脱嵌:充电池时,Li+从正极脱嵌,经过电解质嵌入负极,负极处于富锂状态;放电时则相反。一般采用含有锂元素的材料作为电极的电池。是现代高性能电池的代表。现有的锂电池安全性能不高,常常发生爆炸事故,引起较大的安全隐患。
实用新型内容
(一)要解决的技术问题
本实用新型要解决的技术问题是提供一种带安全保护装置的柱状锂电池,其安全性能高,具有防爆功能。
(二)技术方案
为解决上述技术问题,本实用新型所采用的技术方案是:
一种带安全保护装置的柱状锂电池,包括壳体(7)和电芯(8),所述电芯(8)设置在所述壳体(7)内,所述壳体(7)和电芯(8)之间装有电解液(6),所述壳体(7)上端为敞口,所述电芯(8)上端设有上导线(1),下端设有下导线(9),所述壳体(7)上端部设有密封胶层(4)将该壳体(7)封口,所述上导线(1)穿过所述密封胶层(4),所述密封胶层(4)下表面设有塑料片(5)。
作为优选,所述密封胶层(4)上部设有金属盖(3),所述金属盖(3)和密封胶层(4)之间设有过温保护器(2),所述过温保护器(2)两端分别连接所述上导线(1)和金属盖(3)。
(三)有益效果
本实用新型相比较于现有技术,其具有如下有益效果:其可在不改变现有生产工艺的基础上,提高产品的安全性能,防止发生爆炸,成本低,结构简单,设计新颖,具有实用性。
附图说明
图1是本实用新型的带安全保护装置的柱状锂电池的结构示意图。
具体实施方式
下面结合附图和实施例,对本实用新型的具体实施方式作进一步详细描述。以下实施例用于说明本实用新型,但不用来限制本实用新型的范围。
如图1所示的一种带安全保护装置的柱状锂电池,包括壳体(7)和电芯(8),所述电芯(8)设置在所述壳体(7)内,所述壳体(7)和电芯(8)之间装有电解液(6),所述壳体(7)上端为敞口,所述电芯(8)上端设有上导线(1),下端设有下导线(9),所述壳体(7)上端部设有密封胶层(4)将该壳体(7)封口,所述上导线(1)穿过所述密封胶层(4),所述密封胶层(4)下表面设有塑料片(5)。所述密封胶层(4)上部设有金属盖(3),所述金属盖(3)和密封胶层(4)之间设有过温保护器(2),所述过温保护器(2)两端分别连接所述上导线(1)和金属盖(3)。
当在使用过程中,发生短路现象等致使锂电池温度突然升高,过温保护器可自动断电,保护锂电池。
本实用新型可在不改变现有生产工艺的基础上,提高产品的安全性能,防止发生爆炸,成本低,结构简单,设计新颖,具有实用性。
以上所述仅是本实用新型的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本实用新型技术原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本实用新型的保护范围。
