摘要
研究了Ｂｉ２Ｏ３和ＳｎＯ对铅蓄电池正极活性物质的影响，结果发现Ｂｉ２Ｏ３和ＳｎＯ的复合物比分别加入它们更能提高电池正极活性物质的利用率，利用ＳＥＭ和Ｘ射线衍射研究认为，Ｂｉ２Ｏ３和ＳｎＯ的复合物能大大提高活性物质的导电能力，并改善活性物质的孔隙分布，从而导致活性物质利用率提高１０％。
The effect of Bi 2O 3 and SnO on the utilization of positive active mass(PAM)of lead acid battery has been investigated.It is found that the composite of Bi 2O 3 and SnO improves the utilization of PAM at 5C discharge rate more than any one of them separately.By means of SEM and X ray diffraction,it is established that the composite greatly increases the conductivity of PAM and improves pore distribution of PAM.Therefore 10% of utilization of PAM can be enhanced.
