    Abstract: Low flammability and nonflammable localized superconcentrated electrolytes (LSEs) for stable operation of lithium and sodium ion batteries are disclosed. Electrochemical devices including the low flammability and nonflammable LSEs are also disclosed. The low flammability and nonflammable LSEs include an active salt, a solvent comprising a flame retardant compound, wherein the active salt is soluble in the solvent, and a diluent in which the active salt is insoluble or poorly soluble. The LSE may further include a cosolvent, such as a carbonate, a sulfone, a sulfite, a sulfate, a carboxylate, an ether, a nitrogen-containing solvent, or any combination thereof. In certain embodiments, such as when the solvent and diluent are immiscible, the LSE further includes a bridge solvent.

    Abstract: Electrodeposition involving an electrolyte having a surface-smoothing additive can result in self-healing, instead of self-amplification, of initial protuberant tips that give rise to roughness and/or dendrite formation on the substrate and/or film surface. For electrodeposition of a first conductive material (C1) on a substrate from one or more reactants in an electrolyte solution, the electrolyte solution is characterized by a surface-smoothing additive containing cations of a second conductive material (C2), wherein cations of C2 have an effective electrochemical reduction potential in the solution lower than that of the reactants.

    Abstract: Modifications to the surface of an electrode and/or the surfaces of the electrode material can improve battery performance. For example, the modifications can improve the capacity, rate capability and long cycle stability of the electrode and/or may minimize undesirable catalytic effects. In one instance, metal-ion batteries can have an anode that is coated, at least in part, with a metal fluoride protection layer. The protection layer is preferably less than 100 nm in thickness. The anode material is fabricated according to methods that result in improved anode performance.

    Abstract: The Coulombic efficiency of lithium deposition/stripping can be improved while also substantially preventing lithium dendrite formation and growth using particular electrolyte compositions. Embodiments of the electrolytes include organic solvents and their mixtures to form high-quality SEI layers on the lithium anode surface and to prevent further reactions between lithium and electrolyte components. Embodiments of the disclosed electrolytes further include additives to suppress dendrite growth during charge/discharge processes. The solvent and additive can significantly improve both the Coulombic efficiency and smoothness of lithium deposition. By optimizing the electrolyte formulations, practical rechargeable lithium energy storage devices with significantly improved safety and long-term cycle life are achieved. The electrolyte can also be applied to other kinds of energy storage devices.
