Abstract: Liquid electrolytes for a lithium metal battery comprise an aprotic solvent, an ionic liquid, a lithium salt, 8 mol % to 30 mol % hydrofluoroether and up to 5 mol % additives. A molar ratio of the hydrofluoroether to the lithium salt is 0.22:1 to 0.83:1. The liquid electrolytes achieve at least a 50% improvement in cycle life over conventional electrolytes, extend capacity retention and delay increases in internal resistance.

Abstract: Liquid electrolytes for electrochemical cells with silicon-based anodes are composed of an aprotic solvent, an ionic liquid, a lithium salt, and 8 mol % to 30 mol % hydrofluoroether. A molar ratio of the hydrofluoroether to the lithium salt is 0.22:1 to 0.83:1. The liquid electrolytes achieve at least a 50% improvement in cycle life over conventional electrolytes, extend capacity retention and delay increases in internal resistance.

Abstract: An electrochemical cell has a cathode having a cathode current collector and a cathode active material, an anode having an anode current collector, lithium metal seed, and an anode cap on the lithium metal seed, a liquid electrolyte, a separator between the cathode active material and the anode active material, and a polymer electrolyte lamination layer bonding the anode to the separator. The polymer electrolyte lamination layer is formulated using a crosslinked polymer, a lithium salt, a plasticizer, and an anode additive. The anode cap and the polymer electrolyte lamination layer work together to produce densely plated lithium metal between the lithium metal seed and the anode cap with little or no external pressure.

Abstract: A solid-state cathode for a solid-state electrochemical cell includes an electrochemically active cathode material and one or more elemental dopant residing in grain boundaries of the electrochemically active cathode material. The grain boundaries contain at least 0.2 wt % of the one or more elemental dopant and the one or more elemental dopant is less than 10 wt % of the solid-state cathode. The solid-state cathode does not have liquid, gel and polymer materials.

Abstract: Solid-state battery structures and methods of manufacturing solid-state batteries, such as thin-film batteries, are disclosed. More particularly, embodiments relate to solid-state batteries having an intermediate adhesive layer between several electrochemical cells. In an embodiment, an anode current collector at least partially fills a notch in a periphery of the intermediate adhesive layer. Other embodiments are also described and claimed.
