Sulfide-impregnated solid-state battery

A sulfide-impregnated solid-state battery comprising:

• a cell core constructed by cell units and having a pore structure, each cell unit comprising:
• a positive electrode comprising a cathode layer and a positive meshed current collector comprising a conductive material, wherein the cathode layer is further coated by an oxide-based solid electrolyte layer;
• and
• a negative electrode comprising an anode layer and a negative meshed current collector comprising a conductive material, wherein the anode layer is further coated by an oxide-based solid electrolyte layer,
• wherein the positive electrode and the negative electrode are stacked together to form the cell unit, and the two of the coated oxide-based solid-state electrolyte layers are disposed between the positive electrode and the negative electrode as dual separators,
• wherein the cathode layer comprises between about 30 wt % and about 98 wt % cathode active material, between about 0 wt % and about 50 wt % sulfide-based solid-state electrolyte, between about 0 wt % and about 30 wt % conductive additive, and between about 0 wt % and about 20 wt % binder,
• wherein the anode layer comprises between about 30 wt % and about 98 wt % anode active material, between about 0 wt % and about 50 wt % sulfide-based solid-state electrolyte, between about 0 wt % and about 30 wt % conductive additive, and between about 0 wt % and about 20 wt % binder, and
• wherein a sulfide-base solid-state electrolyte is dispersed in the pore structure of the cell core.
