    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 solid-state battery cell having a capacitor interlayer is disclosed. The solid-state battery includes an anode, a cathode spaced from the anode, a solid-state electrolyte layer disposed between the anode and the cathode, and a capacitor assisted interlayer sandwiched between at least one of (i) the anode and solid-state electrolyte layer, and (ii) the cathode and the solid-state electrolyte layer. The capacitor assisted interlayer comprise at least one of a polymer-based material, an inorganic material, and a polymer-inorganic hybrid material; and a capacitor anode active material or a capacitor cathode active material. The polymer-based material includes at least one of a poly(ethylene glycol) methylether acrylate with Al2O3 and LiTFSI, a polyethylene oxide (PEO) with LiTFSI, and a poly(vinylidene fluoride) copolymer with hexafluoropropylene (PVDF-HFP)-based gel electrolyte. The inorganic material includes a 70% Li2S-29% P2S5-1% P2O5. The polymer-inorganic hybrid material includes a mixture of PEO, LiTFSI, and 75% Li2S-24% P2S5-1% P2O5 (LPOS).

    Abstract: A battery having a plurality of electrodes immersed in a water-in-salt electrolytic solution is disclosed. The water-in-salt electrolytic solution includes a sufficient amount of a lithium salt disposed in an aqueous solvent, at least 14 moles of lithium salt per kg of aqueous solvent, such that a dissociated lithium ion is solvated by less than 4 water molecules. The plurality of electrodes includes a first type electrode, a second type electrode, and a third type electrode selectively assembled in a predetermined order of arrangement into an electrode stack assembly. The first type electrode includes an activated carbon, the second type electrodes include one of a lithium manganese oxide (LMO) and titanium dioxide (TiO2), and the third type electrodes include the other of the LMO and TiO2. The first type electrode may be that of a cathode and/or anode.
