摘　　要：研究了铅碳负极中铅在炭黑、活性炭、石墨表面的电沉积情况,采用扫描电子显微镜法(SEM)、X射线衍射光谱法(XRD)对碳及负极活性物质(NAM)进行表征分析。研究结果表明,铅能沉积在三种碳的表面,碳的微观结构影响沉积铅的形貌,并影响铅碳负极的性能。The electrodepositing of lead on the surface of carbon black, activated carbon and graphite in the lead-carbon negative electrode was studied. Carbon and negative active materials (NAM) were characterized by SEM and XRD. The results show that lead can be deposited on the surface of three types of carbon, and the microstructure of carbon affects the morphology of lead deposition and the properties of lead-carbon negative electrode.
