Description

一种准胶体阀控铅酸蓄电池
技术领域
本实用新型涉及一种准胶体阀控铅酸蓄电池。
背景技术
目前，VRLA电池广泛地应用于通信、电力、铁路、军工以及民用的电动助力车等系统。从VRLA电池运行结果表明，AGM阀控铅酸电池内阻小，大电流性能优越，气体复合效率高，但是AGM隔板电池国内外均没有达到其预期的使用寿命。导致电池提前寿命终结的原因有板栅的腐蚀和增长、活性物质脱落或可用量减少、负极硫酸盐化及极柱的腐蚀等，而更主要的是VRLA电池因电解液“干涸”所致。电解液的“干涸”造成电池局部的酸浓度升高，加速了板栅的腐蚀和铅膏的硫酸盐化。经调查显示，胶体电池使用寿命普遍比AGM隔板电池长，究其原因是由于胶体电池失水缓慢，电解液比较稳定，不易分层，板栅腐蚀较为均匀。
发明内容
本实用新型所要解决的技术问题在于提供一种准胶体阀控铅酸蓄电池，失水缓慢，电解液比较稳定，不易分层，板栅腐蚀较为均匀，使用寿命长。
为解决上述现有技术的问题，本实用新型采用如下方案：一种准胶体阀控铅酸蓄电池，包括电池槽、设在电池槽上的电池盖，所述电池槽内设有正极板、负极板，所述正极板与负极板之间设有AGM隔板，所述电池槽内正极板、负极板和AGM隔板的上方设有胶体电解质保护层。
作为优选，所述电池槽内胶体电解质保护层上方设有汇流排。
有益效果：
本实用新型采用上述技术方案提供一种准胶体阀控铅酸蓄电池，失水缓慢，电解液比较稳定，不易分层，板栅腐蚀较为均匀，使用寿命长。采用AGM隔板与胶体相结合，克服了胶体电池内阻大，大电流放电性能和低温放电性能差的缺点，准胶体电池内阻小，大电流放电性能和低温放电性能好；克服了胶体电池气体复合效率低和AGM电池易漏液的缺点，使得准胶体电池具有较高的气体复合效率，且不易漏液；克服了胶体电池成本高的缺点。胶体保护层的存在，克服了AGM电池电解液不稳定，易分层，板栅腐蚀不均的缺点，使得准胶体电池电解液稳定，不易分层，板栅腐蚀均匀，使用寿命长；克服了AGM电池易失水，使用寿命短的缺点，准胶体电池减缓了失水现象的产生，从而延长了电池的使用寿命。
说明书附图
图1为本实用新型的结构示意图。
具体实施方式
实施例一：
如图1，一种准胶体阀控铅酸蓄电池，包括电池槽1、设在电池槽1上的电池盖2，所述电池槽1内设有正极板3、负极板4，所述正极板3与负极板4之间设有AGM隔板5，所述电池槽1内正极板3、负极板4和AGM隔板5的上方设有胶体电解质保护层6。所述胶体电解质保护层6采用3％的纳米气相二氧化硅、60％的去离子水、37％的硫酸调制而成。所述电池槽1内胶体电解质保护层6上方设有汇流排7。所述的AGM隔板5用于吸收电解液。采用AGM隔板与胶体相结合，克服了胶体电池内阻大，大电流放电性能和低温放电性能差的缺点，克服了AGM电池电解液不稳定，易分层，板栅腐蚀不均的缺点，使得本实用新型失水缓慢，电解液比较稳定，不易分层，板栅腐蚀较为均匀，使用寿命长。
实施例二：
本实施例与实施例一的结构相同，不同的是所述胶体电解质保护层6采用10％的纳米气相二氧化硅、50％的去离子水、40％的硫酸调制而成。
实施例三：
本实施例与实施例一的结构相同，不同的是所述胶体电解质保护层6采用15％的纳米气相二氧化硅、40％的去离子水、45％的硫酸调制而成。
