Abstract:
A sulfide-impregnated solid-state battery is provided. The battery comprises a cell core constructed by basic cell units. Each unit comprises a positive electrode comprising a cathode layer and a positive meshed current collector comprising a conductive material which is further coated by oxide-based solid-state electrolyte. The cell unit further comprises a negative electrode comprising an anode layer and a negative meshed current collector comprising a conductive material which is further coated by oxide-based solid-state electrolyte. The positive and negative electrodes are stacked together to form the cell unit. The two coated oxide-based solid electrolyte layers are disposed between the positive and negative electrode as dual separators. Such a cell unit may be repeated or connected in parallel or bipolar stacking to form the cell core to achieve a desired battery voltage, power and energy. The cell core comprises a sulfide-based solid-state electrolyte dispersed in the pore structures of cell core.
