免维护蓄电池 Pb-Ca 板栅合金的改进

Improved Grid Alloys for Maintenance-free Iead-calcium Batteries

从强度和腐蚀性两方面对Ｐｂ－Ｃａ板栅合金进行讨论，并通过添加合金元素的办法对Ｐｂ－Ｃａ板栅合金进行改进．结果表明，Ｂｉ元素有可能改善Ｐｂ－Ｃａ板栅合金的深充放性能，成为免维护蓄电池的新型板栅合金的添加元素．

Gred alloys for lead-calcium batteries were analyzed in both strength and corrosive resistance, and improved by adding alloying elements to them. with the results, it is shown that it is possible to improve their deep-cycling properties by adding bismuth alloys, which made bismuth into an addition for the improved grid alloys of maintenance-free lead-calcium batteries.
