    Abstract: Disclosed herein are embodiments of a lithium-ion battery system comprising an anode, an anode current collector, and a layer of lithium metal in contact with the current collector, but not in contact with the anode. The lithium compensation layer dissolves into the electrolyte to compensate for the loss of lithium ions during usage of the full cell. The specific placement of the lithium compensation layer, such that there is no direct physical contact between the lithium compensation layer and the anode, provides certain advantages.

    Abstract: The Coulombic efficiency of metal deposition/stripping can be improved while also preventing dendrite formation and growth by an improved electrolyte composition. The electrolyte composition also reduces the risk of flammability. The electrolyte composition includes a polymer and/or additives to form high quality SEI layers on the anode surface and to prevent further reactions between metal and electrolyte components. The electrolyte composition further includes additives to suppress dendrite growth during charge/discharge processes. The electrolyte composition can also be applied to lithium and other kinds of energy storage devices.

    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: 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.
