Description

铅酸蓄电池板栅铅合金
技术领域
本发明涉及电化学技术领域,尤其是一种用于制造铅酸蓄电池板栅的合金。
背景技术
混合电动车用电池是电池行业新增的巨大市场。铅酸蓄电池用于混合电动车以及电动车具有极大的优势,其价格低廉、单体电压稳定、安全性能高,且制造基础良好。
蓄电池的核心部件就是极板,而极板的性能好坏直接决定于板栅和铅膏,板栅的质量好坏取决于板栅铅合金的性能。板栅铅合金的质量,影响到板栅的强度,板栅铅合金中各合金元素的含量对极板的电性能和机械性能影响极大。现有板栅铅合金存在机械强度低,内电阻大等缺陷。
发明内容
本发明所要解决的技术问题是提供一种铅酸蓄电池板栅铅合金,它可以解决蓄电池极板的机械强度低,内电阻大的问题。
为了解决上述问题,本发明的技术方案是:这种铅酸蓄电池板栅铅合金,由下列重量百分比组分的材料熔化制得:钙0.15%~0.18%,锡1.50~1.90%,铝0.04~0.06%,铁≤0.002%,铋≤0.005%,锌≤0.001%,锑≤0.001%,银≤0.001%,铜≤0.0015%,砷≤0.001%,其余为铅。
上述技术方案中,更为具体的方案还可以是:
这种铅酸蓄电池板栅铅合金由下列重量百分比组分的材料熔化制得:钙0.18%,锡  1.50%,铝0.06%,铁0.002%,铋0.005%,锌0.001%,锑0.001%,银0.001%,铜0.0015%,砷0.001%,其余为铅。
进一步:这种铅酸蓄电池板栅铅合金由下列重量百分比组分的材料熔化制得:钙0.15%,锡1.90%,铝0.04%,铁0.002%,铋0.005%,锌0.001%,锑0.001%,银0.001%,铜0.0015%,砷0.001%,其余为铅。
由于采用上述技术方案 ,本发明具有如下有益效果:
1、由于在配方中加入了少量的铝,铝的加入保护了合金中的钙,减少了在熔铸的过程中合金中钙的烧损,从而增强了板栅的强度,板栅的强度的增加,板栅结构可更简练,从而减少了重量。
2、铝的加入稳定了合金中钙的比例,从而减小了板栅的电阻,增强了板栅的导电性,提高了负极的析氢电位,减少了蓄电池在使用过程中电解液中水的损失。
具体实施方式
下面用实施例对本发明进一步详述:
实施例1
这种铅酸蓄电池板栅铅合金由下列重量百分比组分的材料熔化制得:钙0.18%,锡1.50%,铝0.06%,铁0.002%,铋0.005%,锌0.001%,锑0.001%,银0.001%,铜0.0015%,砷0.001%,其余为铅。
实施例2
这种铅酸蓄电池板栅铅合金由下列重量百分比组分的材料熔化制得:钙0.15%,锡1.90%,铝0.04%,铁0.002%,铋0.005%,锌0.001%,锑0.001%,银0.001%,铜0.0015%,砷0.001%,其余为铅。
实施例3
这种铅酸蓄电池板栅铅合金由下列重量百分比组分的材料熔化制得:钙0.16%,锡1.80%,铝0.05%,铁0.001%,铋0.003%,锌0.0005%,锑0.0005%,银0.0005%,铜0.0012%,砷0.0005%,其余为铅。
