摘要 |
A transition metal hexacyanoferrate (TMH) cathode battery is provided. The battery has a AxMn[Fe(CN)6]y .zH2O cathode, where the A cations are either alkali or alkaline-earth cations, such as sodium or potassium, where x is in the range of 1 to 2, where y is in the range of 0.5 to 1, and where z is in the range of 0 to 3.5. The AxMn[Fe(CN)6]y .zH2O has a rhombohedral crystal structure with Mn2+/3+ and Fe2+/3+ having the same reduction/oxidation potential. The battery also has an electrolyte, and anode made of an A metal, an A composite, or a material that can host A atoms. The battery has a single plateau charging curve, where a single plateau charging curve is defined as a constant charging voltage slope between 15% and 85% battery charge capacity. Fabrication methods are also provided. |
