Abstract: An electrolyte includes a lithium (Li) salt, a fluorinated solvent, a 1,3-dioxaolane (DOL) solvent, a 1,2-dimethyoxyethane (DME) solvent, a lithium polysulfide (LiPS), and a lithium nitrate (LiNO3). Lithium sulfur electrochemical devices, such as lithium electrochemical cells and lithium-sulfur batteries, such as lithium-sulfur rechargeable (secondary) batteries include an electrolyte that includes a lithium (Li) salt, a fluorinated solvent, a 1,3-dioxaolane (DOL) solvent, a 1,2-dimethyoxyethane (DME) solvent, a lithium polysulfide (LiPS), and a lithium nitrate (LiNO3).

Abstract: The invention relates to lithium ion batteries and, more particularly, to lithium ion conducting composite polymer electrolyte separators. The separators include a nanofiber mat composed of electrospun nanofibers. The nanofibers include a polymer having one or more polar halogen groups, a lithium-containing solid or liquid electrolyte and nanoparticle filler. The polymer, electrolyte and filler are combined to form a solution that is subjected to the electro-spinning process to produce electrospun nanofibers in the form of the mat.

Abstract: The invention relates to composite multilayer lithium ion battery anodes that include a porous metal alloy foam, and a lithium ion conductor coating applied to the metal alloy foam. The metal alloy foam can include structurally isomorphous alloys of lithium and, optionally, lithium and magnesium. The lithium ion conductor coating can include ternary lithium silicate, such as, lithium orthosilicate. Lithium ions from the ternary lithium silicate may be deposited within the pores of the metal alloy foam. Optionally, the lithium ion conductor coating may include a dopant. The dopant can include one or more of magnesium, calcium, vanadium, niobium and fluorine, and mixtures and combinations thereof.

Abstract: The invention relates to complex framework materials (CFMs) for lithium-sulfur batteries. The CFMs include a CFM host and a coating applied to the CFM host, which includes one or more of an electronic conductor, a lithium ion conductor and a functional catalyst. Further, sulfur is infiltrated into the CFM host creating a sulfur-carbon linkage serving as effective anchors for trapping polysulfides. The systems have been tested in coin cells and pouch cells under lean electrolyte conditions of 3-4 ?l/mg of electrolyte to sulfur ratios showing promise and feasibility.

Abstract: The invention relates to lithium-based battery systems and, more particularly, to electro-spinable solution compositions, electro-spun sulfur-polymer fibers, e.g., wires and yarns, and their use in preparing high performance sulfur mattes, e.g., electrodes, for lithium-sulfur batteries with potential applications in small-scale mobile devices. The sulfur-polymer fibers have nanoscale dimensions and yarn-like morphology. The sulfur-polymer fibers can be prepared by co-dissolving sulfur and polymer in a solvent for forming the electro-spinable solution, and electrospinning the solution. The electrospun fibers can be used to form a composite that includes alternating layers of the electrospun fibers and polymer on a current collector.
