Description

铅酸蓄电池极群紧固结构
技术领域
本发明涉及一种铅酸蓄电池极群紧固结构，属于铅酸蓄电池领域。
背景技术
目前的铅酸蓄电池正板栅合金大部分为铅钙合金，铅钙合金板栅电池在浮充及循环使用的失效模式中，板栅的腐蚀与伸长，造成板栅内阻增大，占了很大的比例。常规的极群结构，板栅上边框上部为极耳及汇流排，有较大形变空间，形变阻力主要在极耳处，上边框极耳以外的其他部位在使用后期变形较明显，加上板栅合金腐蚀的影响，板栅内部筋条易变细，甚至断裂，内阻增大，最终导致电池的失效。
发明内容
本发明的目的在于克服现有极群的不足之处，提供一种能抑制板栅变形和内阻增大，提高电池使用寿命的铅酸蓄电池极群紧固结构。
本发明的技术方案是：铅酸蓄电池极群紧固结构，其改进之处是该极群的顶部和底部分别设有上、下夹板，并由打包带扎紧，上夹板上有极耳孔和透酸孔。
所述极耳孔位置与极群上方的极耳相对应，极耳孔与极耳之间有间隙；所述透酸孔为5～15个，散开分布，中间的一个孔的直径大于其余孔的直径；所述上、下夹板为耐腐蚀高强塑料板，上夹板厚5～7mm，下夹板厚4～6mm，同一极群中上夹板厚度大于下夹板厚度。
本发明适用于正板栅合金为铅钙合金的铅酸蓄电池。
极群焊接前，极群上、下分别加入紧固夹板，上夹板的极耳孔对应电池极耳，然后进行纵向打包，再进行极群焊接，后续工序与常规电池生产工艺一致。夹板上的透酸孔有利于电池的注酸、抽酸。
采用本发明，能使极群内板栅纵向有一定压力，在蓄电池浮充使用或者循环使用过程中，可以有效的抑制板栅的纵向伸长，同时降低板栅伸长、筋条易腐蚀带来的对板栅内阻的影响。另外电池壳体可以有效的抑制板栅横向伸长及弯曲变形，这样板栅在使用后期仍可以保持与初期相近的尺寸形状，保证了电池充放电过程板栅结构的稳定性，电池浮充寿命可以提高30%以上，循环寿命可以提高20%以上。
附图说明
图1为本发明结构示意图。
具体实施方式
参见图1，铅酸蓄电池极群1的顶部设有上夹板3，底部设有下夹板6，两者由打包带5扎紧，上夹板上有与极耳2相应且留有间隙的极耳孔以及透酸孔4，中间的透酸孔直径大于其余透酸孔，上夹板厚6mm，下夹板厚5mm，均采用PC-ABS合金材料。
