Descripción general

Sodium manganese oxide (Na0.44MnO2) electrode sheet is a ready-to-use cathode for sodium-ion battery research. The film is 5 inches x 10 inches (127 mm x 254 mm) and cast single-sided on a 16 µm thick aluminum foil current collector. The composition is 90% sodium manganese oxide (Na0.44MnO2), 5% Poly(vinylidene fluoride) [PVDF] and 5% carbon black. The active material is tunnel-type sodium manganese oxide, which offers fast sodium ionic conductivity and high chemical stability. PVDF acts as binder due to its thermal and electrochemical stability and carbon black boosts the electronic conductivity.

Aplicación

The primary application of our sodium manganese oxide (Na0.44MnO2) electrode sheet is as a cathode for sodium-ion battery research. Manganese-based compounds are widely investigated as cathode materials for rechargeable Na-ion batteries and, in particular, tunnel-type sodium manganese oxide (Na0.44MnO2) is a promising cathode material due to its high capacity, low cost, and non-toxicity. In addition, its unique tunnel structure 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 a variety of electrolytes including NaClO4 and NaPF6-based organic electrolytes.
