Abstract

本发明公开了一种软包装超级电容器消气剂,该消气剂包含如下组分:含有锆基的碳—碳不饱和键的化合物、钡—锂合金、氧化钴、氧化钙中的一种或多种任意比例的组合。所述碳—碳不饱和键是烯烃C-C双键或炔烃C-C三键。该消气剂加入软包装超级电容器内部或涂覆于包装膜内壁,能将电解液所产生的气体合成为新的合成物,防止密封的电容器内部气压升高引发危险,从而有效提高软包装超级电容器的安全性,也能大大延长其循环寿命。

Description

软包装超级电容器消气剂
技术领域
本发明涉及一种超级电容器材料,特别是加入软包装超级电容器内部的消气剂。
背景技术
总所周知,普通结构的超级电容器,包括圆柱型和方形,纽扣型超级电容器,都有着自己的安全阀或防爆阀,有助于将内部形成的气体排出,防止爆炸;而软包装超级电容器却是完全密封的结构,没有排气口和安全阀,所产生的气体被限制在电容器的封装中,受限制的气体会引起电容器内部压力升高,导致超级电容器变软,影响使用性能和寿命,如果气压达到一定程度而未能及时排出,就会发生漏液或者发生爆炸、起火等危险现象。这是软包装超级电容器急需解决的问题。
发明内容
本发明要解决的技术问题是克服现有软包装超级电容器内部气体引发危险的缺陷,提供一种能消除或减少电容器内部气体,提高电容器安全性和使用寿命的软包装超级电容器消气剂。
本发明的技术方案是:该消气剂包含如下组分:含有锆基的碳—碳不饱和键的化合物、钡—锂合金、氧化钴、氧化钙中的一种或多种任意比例的组合。
所述碳—碳不饱和键是烯烃C-C双键或炔烃C-C三键。
在超级电容器的电解液中,目前主要以四乙基四氟化硼酸胺盐(Et4NBF4)溶于乙腈(AN)或碳酸丙烯酯(PC)作为最常用的电解液,其产生的气体可能有:二氧化碳、氮气或氢气及其同位素。采用本发明的消气剂与上述气体接触反应成为氢氧化物、碳酸盐、氮化物及氢化物(氘化物或氚化物)的合成物。对于氢气的合成与消除主要使用含有锆基的消气剂。本消气剂可制成干物质或加入胶粘剂制成膏状物,使用时加入电容器内部,或涂覆于包装膜的内壁,同时可提供保护性氧气屏蔽。消气剂的加入量占电解液的重量百分比为4%~15%。
本发明的有益效果是:消气剂置于软包装超级电容器的内部或涂覆于内壁上,在完全密封的环境下,可将电解液所产生的气体反应合成为新的合成物,防止气压升高引发危险,不仅有效提高超级电容器的安全性,也能大大延长其循环寿命
具体实施方式
将超级电容器电芯放置于已裁定好尺寸的铝塑包装膜内,并加入消气剂于铝塑包装膜的内部或涂于包装膜内壁,制作成方形软包装超级电容器,电解液从注液口加入,然后再密封。消气剂的组分、用量和使用效果如下表:
