Description

无汞锌锰和锌银扣式电池
技术领域
本实用新型涉及一种无汞锌锰和锌银扣式电池。 
背景技术
现有的无汞锌锰和锌银扣式电池生产技术，采用电镀方法在负极盖表面镀上一层可提高析氢过电位的金属铟、锡或铟锡、铟锌、铜锡合金等，但是由于电镀上述金属或合金存在电镀液离子浓度和PH值难控制而造成镀层不均匀或镀层有孔洞等缺馅，会导致负极锌膏与负极盖内侧里面的镀铜层或镀镍层接触、甚至与负极盖金属基体接触发生化学反应而产生气体，因扣式电池尺寸很小，电池内部不能留有空间容纳气体导致电池膨胀、漏液、爆炸。现有的无汞锌锰和锌银扣式电池结构，存在密封性能不足，容易导致负极电解液从负极盖与密封胶圈之间漏出，造成爬碱、漏液。另外，现有技术生产的无汞锌锰和锌银扣式电池负极盖，电镀后还需将外表面的镀层进行退镀，操作复杂、繁琐，而且电镀、退镀会造成环境污染及资源浪费，因此急需一种方法既环保又有效克服现有的无汞锌锰和锌银扣式电池技术的不足。 
发明内容
本实用新型的目的是提供一种无汞锌锰和锌银扣式电池。通过该方法制备的无汞锌锰和锌银扣式电池，其电池负极盖凹面带有负极集流体与密封膜，负极集流体将负极锌膏与负极盖内表面隔开，避免了负极锌膏与负极盖内侧接触发生化学反应而产生气体导致电池膨胀，克服了现有的无汞锌锰和锌银扣式电池技术的不足。 
本实用新型是在电池负极盖的凹面带有负极集流体与密封膜，负极集流体由0.01-0.15mm厚的金属铟、锡或铟锡合金、铟锌合金、锡铜合金制成，并与塑料、尼龙或橡胶制成的密封膜连成一体化，负极集流体采用的金属铟、锡或铟锡合金、铟锌合金、锡铜合金能提高锌粉的析氢过电位，有效防止电池自放电析氢，负极集流体将负极锌膏与负极盖隔开，有效防止了负极锌膏与负极盖内侧接触发生化学反应而产生气体导致电池气胀、爆炸，密封膜把负极锌膏与负极盖、密封胶圈隔开，避免负极电解液从负极盖与密封胶圈之间漏出，有效防止了电池爬碱、漏液。 
附图说明
图1是本实用新型实施例所述的无汞锌锰和锌银扣式电池的剖面图。 
图2是本实用新型实施例所述的无汞锌锰和锌银扣式电池负极集流体与密封膜的剖面图。 
具体实施方式
以下结合附图及实施例，对本实用新型进行进一步详细说明。 
负极集流体由0.01-0.15mm厚的金属铟、锡或铟锡合金、铟锌合金、锡铜合金制成，并与塑料、尼龙或橡胶制成的密封膜连成一体化，将常规工艺生产的普通扣式电池用的负极盖（负极盖外表面不用退镀）与密封胶圈组合成电池负极盖组合件，然后把负极集流体与密封膜一体化组件安装在负极盖组合件凹面上，再按常规工艺便可制成无汞锌锰和锌银扣式电池。正极材料使用电解二氧化锰制成无汞锌锰扣式电池，用氧化银代替电解二氧化锰制成无汞锌银扣式电池。
如图1所示，本实用新型实施例所述的无汞锌锰和锌银扣式电池，包括本实施例所述的负极集流体3与密封膜4一体化组件，负极盖1及密封胶圈2、负极锌膏5、隔膜6、正极材料7、正极壳8，负极集流体采用的金属铟、锡或铟锡合金、铟锌合金、锡铜合金能提高锌粉的析氢过电位，有效防止电池自放电析氢，负极集流体3将负极锌膏5与负极盖1内表面隔开，有效防止了负极锌膏5与负极盖1内侧接触发生化学反应而产生气体导致电池气胀、爆炸，密封膜4把负极锌膏5与负极盖1、密封胶圈2隔开，避免负极电解液从负极盖1与密封胶圈2之间漏出，有效防止了电池爬碱、漏液。 
如图2所示，本实用新型实施例所述的无汞锌锰和锌银扣式电池负极集流体与密封膜一体化组件，负极集流体由0.01-0.15mm厚的金属铟、锡或铟锡合金、铟锌合金、锡铜合金1制成，并与塑料、尼龙或橡胶制成的密封膜2连成一体化。 
以上所述仅为本实用新型的典型实施例，但并不局限于此例，凡在本实用新型的精神本质和原理所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
