摘　　要：使用氟化碳和电解二氧化锰混合材料为正极的锂原电池,在放电过程中两种材料都能正常发挥其自身容量,且整个反应过程经历了先EMD、后混合、再CFx放电的过程。SEM和XRD测试证明了混合材料在整个电极反应过程中没有副产物生成。对氟化碳材料和二氧化锰材料进行合理的混合,可得到性能最佳、最能发挥二者性能的电极。Both the fluorinated carbon(CFx)and electrolytic manganese dioxide(EMD)would exhibit their discharging capacity perfectly,where the two kinds of material are mixed up as the cathode in a primary Li cell.And the order of discharge in the whole discharge process was the EMD firstly,and then both the two materials,finally the CFx.We could demonstrate that there are no by-products in the discharge process through the analysis of SEM and XRD.The discharge performance of CFxand EMD as the mixed cathode of Li primary cell was independent,and the two materials are non-interfering with each other in the discharge process.
