Title: METAL PLATING-BASED ELECTRICAL ENERGY STORAGE CELL
Abstract:
The present disclosure provides an electrochemical storage cell including a battery. The battery includes an alkali metal anode having an anode Fermi energy, an electronically insulating, amorphous, dried solid electrolyte able to conduct alkali metal, having the general formula A3-xHxOX, in which 0 ≤ x ≤ 1, A is the alkali metal, and X is at least one halide, and a cathode including a cathode current collector having a cathode Fermi energy lower than the anode Fermi energy. During operation of the electrochemical storage cell, the alkali metal plates dendrite-free from the solid electrolyte onto the alkali metal anode. Also during operation of the electrochemical storage cell, the alkali metal further plates on the cathode current collector.
