Molten inorganic electrolytes for low temperature sodium batteries
| DWPI Title: Inorganic molten salt catholyte used in electrochemical energy storage comprises sodium halide having sodium fluoride, sodium chloride, sodium bromide or sodium iodide mixed with metal halide |
| Abstract: A molten sodium-based battery comprises a robust, highly Na-ion conductive, zero-crossover separator and a fully inorganic, fully liquid, highly cyclable molten cathode that operates at low temperatures. |
| Use: The catholyte is useful: for electrochemical energy storage (claimed); and in low temperature molten sodium batteries. |
| Advantage: The catholyte provides the low temperature molten sodium batteries that leverage a liquid, fully inorganic molten salt catholyte for safe and long-lifetime energy storage. |
| Novelty: Inorganic molten salt catholyte comprises at least one sodium halide comprising sodium fluoride, sodium chloride, sodium bromide or sodium iodide mixed with at least one metal halide (MXy) , where M is magnesium, calcium, strontium, barium, niobium, tantalum, molybdenum, tungsten, gallium, indium, tin, antimony or bismuth and X is fluoride, chloride, bromide or iodide. |
