    Abstract: A method of making a reference electrode assembly for an electrochemical cell according to various aspects of the present disclosure includes providing a subassembly including a separator layer and a current collector layer coupled to the separator layer. The method further includes providing an electrode ink including an electroactive material, a binder, and a solvent. The method further includes creating a reference electrode precursor by applying an electroactive precursor layer to the current collector layer. The electroactive precursor layer covers greater than or equal to about 90% of a superficial surface area of a surface of the current collector layer. The electroactive precursor layer includes the electrode ink. The method further includes creating the reference electrode assembly by drying the electroactive precursor layer to remove at least a portion of the solvent, thereby forming an electroactive layer. The electroactive layer is solid and porous.

    Abstract: The present disclosure relates to solid-state electrolytes and methods of making the same. The method includes admixing a sulfate precursor including one or more of Li2SO4 and Li2SO4.H2O with one or more carbonaceous capacitor materials. The first admixture is calcined to form an electrolyte precursor that is admixed with one or more additional components to form the solid-state electrolyte. When a ratio of the sulfate precursor to the one or more carbonaceous capacitor materials in the first admixture is about 1:2, the electrolyte precursor consists essentially of Li2S. When a ratio of the sulfate precursor to the one or more carbonaceous capacitor materials in the first admixture is less than about 1:2, the electrolyte precursor is a composite precursor including a solid-state capacitor cluster including the one or more carbonaceous capacitor materials and a sulfide coating including Li2S disposed on one or more exposed surfaces of the solid-state capacitor cluster.

    Abstract: A capacitor-assisted electrochemical cell according to various aspects of the present disclosure includes at least two first electrodes including one or more positive electroactive material layers disposed in electrical communication with a positive current collector; at least one second electrode including one or more first negative electroactive material layers disposed in electrical communication with a first negative current collector; and at least one composite electrode including one or more second negative electroactive material layers disposed in electrical communication with a second negative current collector. The second negative electroactive material layers may be in the form of a plurality of negative electroactive particles including one or more of a carbonaceous material and a metal oxide. Each negative electroactive particle may have a plurality of pores and a plurality of sulfur-additive particles disposed within the plurality of pores.

    Abstract: An electrolyte membrane for a battery that cycles lithium ions includes a sulfide-based solid electrolyte, a polymer binder, an inorganic filler, an inorganic lithium salt, and an ionic liquid. The sulfide-based solid electrolyte includes lithium sulfide (Li2S) and at least one element selected from the group consisting of phosphorus (P), tin (Sn), silicon (Si), germanium (Ge), boron (B), gallium (Ga), and aluminum (Al). The ionic liquid includes substantially equimolar amounts of a cation and an anion. The cation includes a complex of lithium (Li+) and an ethylene glycol dimethyl ether, an imidazolium ion, a piperidinium ion, a pyrrolidinium ion, an ammonium ion, a phosphonium ion, or a combination thereof. The anion includes an arsenate ion, a phosphate ion, a sulfonylimide ion, a borate ion, a chlorate ion, or a combination thereof.
