铅酸蓄电池中硫化氢产生的分析研究

Analysis of hydrogen sulfide produced in lead-acid battery

铅酸蓄电池在充电过程中可能会产生臭鸡蛋气味的、对人体有害的难闻气体。选择不同类型的免维护铅酸蓄电池对该气体的成分以及产生的原因进行研究。结果表明,该气体为硫化氢气体。它的产生受电化学反应、温度、电解液密度、电压和电流等共同影响。最后根据研究结果对其产生机理进行了推测。

During charging process,lead acid battery can produce the gas that gives rotten eggs their unpleasant smell,which may cause damage to our body.According to this problem,different types of maintenance-free lead acid battery were selected to find out what the gas was and how the gas produced.The results show that the gas is hydrogen sulfide,which is caused by electrochemical reaction,temperature,acid density,voltage and current etc.In the end,by the results,the causing mechanism of hydrogen sulfide was speculated.
