Abstract: An anode-free solid-state battery includes a cathode layer having transient anode elements and a bare current collector devoid of non-transitory anode material and configured to accept thereon the transient anode elements. The battery also includes a solid-state electrolyte layer defining voids and arranged between the current collector and the cathode layer. The battery additionally includes a gel situated within the solid-state electrolyte and cathode layers, to permeate the electrolyte voids and form a gelled solid-state electrolyte layer, coat the cathode layer, and facilitate ionic conduction of the anode elements between the cathode layer, the solid-state electrolyte layer, and the current collector. Charging the battery diffuses the anode elements from the cathode layer, via the gelled solid-state electrolyte layer, onto the current collector. Discharging the battery returns the anode elements, via the gelled solid-state electrolyte layer, to the cathode layer. A particular method is used to fabricate the anode-free solid-state battery.

Abstract: A hybrid lithium-ion battery/capacitor cell comprising at least a pair of graphite anodes assembled with a lithium compound cathode and an activated carbon capacitor electrode can provide useful power performance properties and low temperature properties required for many power utilizing applications. The graphite anodes are formed of porous layers of graphite particles bonded to at least one side of current collector foils which face opposite sides of the activated carbon capacitor. The porous graphite particles are pre-lithiated to form a solid electrolyte interface on the anode particles before the anodes are assembled in the hybrid cell. The pre-lithiation step is conducted to circumvent the irreversible reactions in the formation of a solid electrolyte interface (SEI) and preserve the lithium content of the electrolyte and lithium cathode during formation cycling of the assembled hybrid cell. The pre-lithiation step is also applicable to other anode materials that benefit from such pre-lithiation.

Abstract: A method of making the sulfide-impregnated solid-state battery is provided. The method comprises providing a cell core that is constructed by cell unit. The cell core is partially sealed into the packaging such as the Al laminated film and metal can. The method further comprises introducing a sulfide solid-state electrolyte (S-SSE) precursor solution in the cell core, the S-SSE precursor solution comprises a sulfide solid electrolyte and a solvent. The method further comprises evaporating the solvent from the cell core to dry the cell core to solidify the sulfide-based solid-state electrolyte within the cell core and pressurizing the cell core to densify the solid sulfide-base electrolyte within the cell core. The cell core is then fully sealed.
