万松蓄电池电解液,所述电解液包括以下重量百分比的组分:气相二氧化硅0.8%?1.2%、稀硫酸89%?90%、硫酸盐0.8%?1.2%,其余为纯水;还公开了其制备方法,1)确认好稀硫酸密度、温度;2)计算稀硫酸、气相二氧化硅、纯水、硫酸盐重量,将硫酸盐溶解到纯水中,然后将稀硫酸和水导入搅拌机,在搅拌状态均匀加入配方所需气相二氧化硅,继续搅拌20~40min,即可得到所述电解液。可以使胶体电解液均匀分布在电池内部,解决胶体电解液渗透不均匀的问题,且气相二氧化硅溶入电解液中,充电前就加入电池内部,不需要充电后再单独添加,没有二次添加胶体电解液的操作。
The invention belongs to the field of lead-acid batteries, and discloses an AGM colloidal battery electrolyte, which comprises the following components of weight percentage: gaseous silica 0.8%1.2%, dilute sulfuric acid 89%90%, sulfate 0.8%1.2%, and the rest is pure water; the preparation method is also disclosed, 1) confirming the density and temperature of dilute sulfuric acid; 2) calculating dilute sulfuric acid and gaseous silica. The electrolyte can be obtained by dissolving the sulfate into the pure water, then introducing the dilute sulfuric acid and water into the mixer, evenly adding the gas-phase silica required for the formulation in the stirring state, and stirring for 20-40 minutes. The invention can make colloidal electrolyte evenly distribute in the battery, solve the problem of non-uniform permeation of colloidal electrolyte, and gas-phase silicon dioxide is dissolved into the electrolyte, which is added into the battery before charging, without adding the colloidal electrolyte separately after charging, and without the operation of adding the colloidal electrolyte twice.
密封结构包括顶盖,所述顶盖上设有多个正极接头和至少一个负极接头,所述顶盖中部设有通孔,所述负极接头设置于所述通孔内,并与所述顶盖绝缘设置;多个所述正极接头均匀分布于所述负极接头的外围,且其一端与所述顶盖固定连接;所述正极接头与所述负极接头之间还设有多个绝缘件;所述负极接头与所述顶盖之间还设有多个密封件。此结构的密封结构,用于高温储能电池上,由于在正极接头和负极接头之间设置多个绝缘件,并同时在负极接头与顶盖之间设置多个密封件,使得密封结构的绝缘性能和密封性能都得到了有效提高,可有效防止由于密封及绝缘性能不足导致的高温储能电池失效。
技术介绍
对比AGM电池,万松蓄电池有高循环寿命、容量稳定、深放电能力、热失控敏感性良好、酸层化现象弱等优点,但是其高成本却让生产商望而却步,行业上很多铅酸电池生产商在AGM电池电解液内添加气象二氧化硅或硅酸以达到与胶体电池优势互补的目的,不过厂商的添加方法和添加比例差异很大,比较多的是AGM电池充电后往电池内部倒入胶体电解液,使其与硫酸反应后扩散到电池内部,实际上,这种操作方法胶体电解液大部分分布在电池表层,没有渗透到极群、隔板中间,没有起到优势互补的作用。
