摘要：Cryotolerance-type manganese oxide (KMn₈O₁₆) nanorods were prepared for the first time by a rheological phase reaction method. The KMn₈O₁₆ samples were characterized by X-ray diffraction, scanning electron microscopy, the effects of different annealed temperatures on the morphologies and electrochemical properties of the final products were systematically investigated. The result that the annealed samples exhibit the superior electrochemical performances compared to the unannealed sample. The KMn₈O₁₆ nanorods annealed at 400 °C show the highest reversible discharge capacity (147.9 mAh/g even after 80 cycles) at current density of 50 mA/g and the best cycling stability. These results indicate that the KMn₈O₁₆ nanorods could be a promising cathode material for lithium ion batteries.
