Abstract

一种电池装配方法,包括一个组装电极卷、正集流体、负集流体、罐体和盖子的过程,首先卷绕电极卷,然后将正集流体和负集流体分别焊接在电极卷的两端,之后利用感应加热设备将罐体底部加热到180~200℃,然后将正集流体朝下装进罐体内,然后将盖子加热到200℃并保持2小时,最后将加热好的盖子装到负集流体上。本发明在电池组装过程中,利用感应加热设备分别加热罐体底部和盖子,然后分别装入正集流体、负集流体,罐体、盖子冷却后,与正集流体、负集流体紧密接触,减少了接触电阻,在不改变电极材料的条件下,增加了电池的容量,同时由于内阻减小从而减小了电池的发热量,提高了电池在使用过程中的安全性。

Description

一种电池装配方法
技术领域:
本发明涉及电学领域,尤其涉及化学电池,特别是一种电池装配方法。
背景技术:
现有技术中,电池的电极卷与外壳或其他零件间存在接触电阻,接触电阻使电池内部存在电能消耗,导致电池容量减少。此外,接触电阻的存在,使电池在使用过程中容易发热,安全性差。
发明内容:
本发明的目的在于提供一种电池装配方法,所述的这种电池装配方法要解决现有技术中电池内零件间接触电阻导致电池容量减少、使用过程中容易发热的技术问题。
本发明的这种电池装配方法包括一个组装电极卷、正集流体、负集流体、罐体和盖子的过程,其中,在所述的组装电极卷、正集流体、负集流体、罐体和盖子的过程中,首先卷绕电极卷,然后将正集流体和负集流体分别焊接在电极卷的两端,之后利用感应加热设备将罐体底部加热到180~200℃,然后将正集流体朝下装进罐体内,然后将盖子加热到200℃并保持2小时,最后将加热好的盖子装到负集流体上。
本发明的工作原理是:罐体底部加热到180~200℃时,体积膨胀,然后装入正集流体,罐体冷却后,与正集流体紧密接触,减少了接触电阻。盖子加热到200℃并保持2小时,盖子体积膨胀,然后装上负集流体,盖子冷却后,与负集流体紧密接触,减少了接触电阻。
本发明和已有技术相比,其效果是积极和明显的。本发明在电池组装过程中,利用感应加热设备分别加热罐体底部和盖子,然后分别装入正集流体、负集流体,罐体、盖子冷却后,与正集流体、负集流体紧密接触,减少了接触电阻,在不改变电极材料的条件下,增加了电池的容量,同时由于内阻减小从而减小了电池的发热量,提高了电池在使用过程中的安全性。
附图说明:
图1是本发明一种电池装配方法的一个实施例的示意图。
具体实施方式:
实施例1:
如图1所示,本发明的电池装配方法,包括一个组装电极卷5、正集流体3、负集流体2、罐体4和盖子1的过程,其中,在所述的组装电极卷5、正集流体3、负集流体2、罐体4和盖子1的过程中,首先卷绕电极卷5,然后将正集流体3和负集流体2分别焊接在电极卷5的两端,之后利用感应加热设备将罐体4底部加热到180~200℃,然后将正集流体3朝下装进罐体4内,然后将盖子1加热到200℃并保持2小时,最后将加热好的盖子1装到负集流体2上。
本发明的工作原理是:罐体4底部加热到180~200℃时,体积膨胀,然后装入正集流体3,罐体4冷却后,与正集流体3紧密接触,减少了接触电阻。盖子1加热到200℃并保持2小时,盖子1体积膨胀,然后装上负集流体2,盖子1冷却后,与负集流体2紧密接触,减少了接触电阻。
