The synthesis of manganese dioxide by spray pyrolysis has been investigated as a cathode material of lithium/manga­ nese dioxide cell. Spraying solutions with Na/Mn ratios of 0.0-0.7 were prepared by mixing sodium acetate and man­ ganese acetate. Sodium manganese composite oxides were obtained by spray pyrolysing the resulting solutions at 500°C . y-Mn02 was formed by extraction of sodium ion from the composite oxides in nitric acid solution. The forma­ tion of a-Mn02 phase was obse1ved with Na/Mn ratios of above 0.3. The powders were in a range of 0.5-2μm and the specific surface areas were 221-254而g-1. The discharge capacities (281-283 m仙g1) of the products obtained with Na/Mn ratios of below 0.3 were higher than that of electrolytic manganese dioxide (207 mAh g1).
