Title: RECHARGEABLE SODIUM CELLS FOR HIGH ENERGY DENSITY BATTERY USE
Abstract:
An electrochemical cell for an energy- dense rechargeable battery is provided. The cell includes a solid metallic sodium anode, which is deposited over a suitable current collector during the cell charging process. Several variations of compatible electrolytes are disclosed, along with novel cathode materials for building the complete high-energy battery cell.
