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: Electrodes are formed with a porous layer of particulate electrode material bonded to each of the two major sides of a compatible metal current collector. In one embodiment, opposing electrodes are formed with like lithium-ion battery anode materials or like cathode materials or capacitor materials on both sides of the current collector. In another embodiment, a battery electrode material is applied to one side of a current collector and capacitor material is applied to the other side. In general, the electrodes are formed by combining a suitable grouping of capacitor layers with un-equal numbers of anode and cathode battery layers. One or more pairs of opposing electrodes are assembled to provide a combination of battery and capacitor energy and power properties in a hybrid electrochemical cell. The cells may be formed by stacking or winding rolls of the opposing electrodes with interposed separators.
