Application

Our high-purity sodium manganese oxide, Na0.44MnO2, powder is suitable and tested for use as a cathode material in Na-ion batteries. Na0.44MnO2 is promising for use in sodium-ion batteries because of its unique tunnel structure, which facilitates excellent cycle and rate performance. For example, our sodium manganese oxide showed a large capacity (experimentally 110 mAh g−1 at 0.1C), even at fast charge rates (80 mAh g-1 at 5C, 72%). In addition, Na0.44MnO2 shows excellent stability with NaClO4 and NaPF6-based organic electrolytes and also aqueous electrolytes.

General description

Sodium manganese oxide is a powdery black substance, which crystallizes in an orthorhombic tunnel-type structure. The structure’s interconnected S-shaped tunnels offer wide diffusion paths for fast and reversible sodium intercalation.
