二氧化铅电极的晶体结构对放电容量的影响

Effect of Crystal Structure of PbO_2 Electrode on Its Discharge Capacity

采用铅镉合金镀层经处理制备活性二氧化铅电极 ,利用TEM、XRD、XPS等方法研究了二氧化铅电极表层晶体结构 ,证实了无定形相的存在 ,实验结果表明 ,铅镉合金中铅含量越低 ,所形成的活性二氧化铅结晶度越大 ,电极的放电容量也越高 .

An active PbO 2 electrode was prepared from Pb Cd alloy. The existence of amorphous phase in the electrode surface has been confirmed by TEM, XRD and XPS. The results showed that the lower the content of Pb in alloy, the higher the crystallinity of the active PbO 2 and the discharge capacity of the electrode.
