Abstract
The present disclosure relates to rechargeable electrochemical battery cells (molten air batteries). The cells use air and a molten electrolyte, are quasi-reversible (rechargeable) and have the capacity for multiple electrons stored per molecule and have high intrinsic electric energy storage capacities. The present disclosure also relates to the use of such in a range of electronic, transportation and power generation devices, such as greenhouse gas reduction applications, electric car batteries and increased capacity energy storage systems for the electric grid.
Claims30
A rechargeable battery cell comprising:
- a) a rechargeable air electrode;
- b) a rechargeable non-metal electrode that is capable of being oxidized;
- and
- c) a molten electrolyte disposed between the air electrode and the non-metal electrode;
- wherein at the air electrode, the principal reaction is oxygen (O2) being reduced during discharge, the principal reaction is not carbon dioxide (CO2) and oxygen (O2) being reduced to form carbonate (CO3−2) during discharge, and
- wherein the molten electrolyte comprises one or more metal carbonates,
- wherein external carbon dioxide (CO2) is not required for discharge at the air electrode.
