摘　　要：为克服目前高温烘箱法处理Li/MnO2电池用EMD时锰粉受热不均、加热时间过长等缺点,采用自行设计的回转炉处理EMD.XRD分析结果表明,EMD经回转炉和烘箱热处理,其晶型结构均从γ-MnO2转变为γ,β-MnO2,但相同温度下,前者比后者用时短,β-MnO2含量高.将热处理过的EMD制成电池并在室温下恒电流和恒电阻连续放电,结果表明,回转炉处理的EMD放电容量较烘箱热处理高,电性能好.EMD was treated by revolving stove for Li/MnO2 batteries to overcome the shortcomings of high temperature oven, which took too long and could not heat the powder up uniformly. The results of X ray diffractions showed that EMD had been converted from γ-MnO2 into γ,β-MnO2 after thermally treated by those two means. However, the former method got more β-MnO2 and needed less time than the latter at the same temperature. The discharging results under load and at current invariable showed that the batteries with EMD treated by revolving stove had higher discharge capacities than those by high temperature oven.
