Abstract: Centering on the long-life lead-acid batteries for E-bikes, this paper mainly explores the interior structural design, grid alloy, curing and the container formation processes. The experimen results show that the service life of lead-acid batteries at high current is prolonged when the strap structure of overall cast joint and direct epoxy sealing is adopted. By adding rare earth and silver to grid alloy, the grid corrosion resistance and creep resistance can be improved. The reasonable curing process and charging quantity can improve the bonding strength of grid and active materials, which greatly extend the life of lead-acid battery.
Key words: long-life battery; E-bike; grid; curing; container formation

随着电动自行车性能的改进,要求电池使用寿
命越来越长。所以,近两年一些电动自行车生产厂收稿日期:2014-09-30
家要求将电池的三包期提高到两年以上,同时对电池高倍率放电性能提出了更高的要求。为了适应整车厂的要求,研究超长寿命的蓄电池显得越来越紧追和重要。但由于环保的进一步趋紧,寿命性能相对较好的铅锑镐合金已处于禁用状态,铅钙合金成为了自行车电池的首选合金,而铅钙合金电池寿命的影响因素众多,寿命相对较短。本文对电池的结构设计、板栅合金、极板固化和化成充电工艺进行了研究,探讨如何延长铅钙合金电池的寿命。
