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.

Liquid electrolyte for lithium metal battery

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.

Electrochemical cell design with lithium metal anode

An anode for a lithium metal battery includes a host structure configured to be between an anode current collector and a separator, the host structure having void spaces configured to host metallic lithium during charging, wherein the host structure has a void space of &#x2265;60% and &#x2264;80%. Another anode for a lithium metal battery includes a current collector, a separator, and a host structure between the current collector and the separator, the host structure having void spaces configured to host metallic lithium during charging, wherein the host structure is formed of fibers.

A liquid electrolyte for a lithium metal battery comprises 45-65 mol % of an aprotic solvent, 5-15 mol % of an ionic liquid, 28-44 mol % of a lithium salt and up to 5 mol % additives. The aprotic solvent consists of one or more of a linear carbonate and a linear ether and the ionic liquid consists of one or more of PYRFSI, PYRFSI, PYRTFSI, and PYRTFSI. The lithium salt is selected from the group consisting of LiFSI, LiTFSI, and LiBET. The liquid electrolyte can have a flash point of greater than 60&#xb0; C. and a dynamic viscosity of less than 120 mPa&#xb7;s.

Liquid electrolyte for a lithium metal battery

An anode for a lithium metal battery has a current collector formed of a flexible polymer substrate having an anode-facing surface, the polymer substrate formed of a polymer chemically compatible with lithium metal. A current pathway of a first conductive metal is embedded in the polymer substrate and has a terminal end extending from an end of the polymer substrate. Traces of a second conductive metal each have a current collecting portion at the anode-facing surface, the traces in electrical communication with the current pathway. Lithium metal is deposited onto the current collector.

Corrosion resistant current collector for lithium metal anode

An anode for a lithium metal battery includes a current collector, a seed layer deposited onto the current collector, the seed layer comprising a seed material selected to promote electrochemical plating of metallic lithium onto the seed layer, a separator, a host structure between the seed layer and the separator, the host structure having void spaces configured to host metallic lithium during charging, a first adhesion layer bonding the host structure to the seed layer, and a second adhesion layer bonding the host structure to the separator.

In a plasma enhanced physical vapor deposition of a material onto workpiece, a metal target faces the workpiece across a target-to-workpiece gap less than a diameter of the workpiece. A carrier gas is introduced into the chamber and gas pressure in the chamber is maintained above a threshold pressure at which mean free path is less than 5% of the gap. RF plasma source power from a VHF generator is applied to the target to generate a capacitively coupled plasma at the target, the VHF generator having a frequency exceeding 30 MHz. The plasma is extended across the gap to the workpiece by providing through the workpiece a first VHF ground return path at the frequency of the VHF generator.
