    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.

    Abstract: The present disclosure provides a modified binder for use in an electrochemical cell that cycles lithium ions. The modified binder includes one or more agglomerates of polytetrafluoroethylene nanoparticles, where each of the polytetrafluoroethylene nanoparticles includes a polytetrafluoroethylene core and a polymeric shell that is disposed on exposed surfaces of the core. The polymeric shell can include a polymer selected from the group consisting of: polyethylene oxide, polyglycidyl methacrylate, polyvinylidene difluoride, fluoride-hexafluoropropylene, polypropylene oxide, polyacrylonitrile, polymethacrylonitrile, polymethyl methacrylate, derivatives and co-polymers, and combinations thereof, and in certain instances, also a humidity tolerant lithium salt. The polytetrafluoroethylene core can have a first particle size ranging from about 10 nanometers to about 500 nanometers, the polymeric shell can have an average thickness ranging from about 10 nanometers to about 1,000 nanometers, and each of the one or more agglomerates can have an average size ranging from about 100 micrometers about 1,000 micrometers.

    Abstract: A capacitor-assisted battery is provided. The capacitor-assisted battery includes an electrolyte system having a lithium-ion conducting component and one or more additives. The one or more additives include a first additive that includes 3-trimethylsilylphenylboronic acid, and a second additive that includes succinic anhydride. The capacitor-assisted battery includes an electrode having an electroactive material and a capacitor material. The electroactive material has a first coating defined thereon, and the capacitor material has a second coating defined thereon. The first and second coatings are defined by the first and second additives. The first coating is a substantially continuous that covers greater than or equal to about 80%, of a total exposed surface area of the electroactive material. The second coating is a discontinuous coating covers greater than or equal to about 20% to less than or equal to about 80% of a total exposed surface area of capacitor material.

    Abstract: The present disclosure provides an electrochemical cell that cycles lithium ions, where the electrochemical cell includes an electrode, a solid-state electrolyte layer, and a solid-state interlayer disposed between the electrode and the solid-state electrolyte layer. The solid-state interlayer includes a plurality of solid-state electrolyte particles. In certain instances, the solid-state interlayer includes a plurality of through-holes dispersed therewithin. The through-holes have an average diameter between about 0.05 to about 100 micrometers. The solid-state interlay covers between about 50% and about 100% of a total surface area of the electrode. In each variation, solid-state interlayer has a thickness greater than or equal to about 0.1 to less than or equal to about 8 micrometers, and the electrochemical cell may include a polymeric gel electrolyte that at least partially fills voids between solid-state electroactive particle and solid-state electrolyte particles.
