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: An anode electrode with enhanced state of charge estimation is provided. The anode electrode comprises anode layer and a negative current collector. The negative current collector has a first side and a second side. The anode layer comprises lithium-titanium oxide and a second anode material (e.g. niobium-titanium oxide) disposed on at least one of the first and second sides of the negative current collector with single-layer or layer-by-layer coated structures. The second anode material (e.g. niobium-titanium oxide) can be physically blended with lithium-titanium oxide or be at least partially coated on the surface of lithium-titanium oxide or their combinations. The anode electrode further comprises a binder and a conductive carbon.

Abstract: A hybrid lithium ion capacitor battery and method of making the same is disclosed. The hybrid lithium ion capacitor battery includes a positive electrode separated from a negative electrode by a separator layer. A first activated carbon layer is disposed between the separator layer and one of the positive and negative electrodes. The first activated carbon layer is coated on a first surface of the separator layer. A second activated carbon layer is disposed between the separator layer and the other of the positive and negative electrodes. The second activated carbon layer is coated on a second surface of the separator layer. A first current collector coextensively contacts the first electrode and a second current collector coextensively contacts the second electrode. An electrolytic solution carries lithium cations between the positive and negative electrodes through the activated carbon coated separator layer.

Abstract: In an embodiment, a softened solid-state electrolyte, comprises an oxide-based solid-state electrolyte, where at least a portion of the oxide anions in the oxide-based solid-state electrolyte is replaced with a replacement anion. In another embodiment, a softened solid-state electrolyte comprises a sulfide-based solid-state electrolyte, wherein at least a portion of the sulfide anions in the sulfide-based solid-state electrolyte is replaced with the replacement anion. When the replacement anion replaces the oxide anion, the replacement anion has a larger atomic radius than the oxide anion and when the replacement anion replaces the sulfide anion, the replacement anion has a larger atomic radius than the sulfide anion.

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.
