A lithium metal electrode comprises a layer of lithium metal coating a conductive substrate, the layer of lithium metal having no more than five ppm of non-metallic elements by mass. The layer of lithium metal is in turn coated with a lithium ion conductive conformable polymer, thereby providing the negative electrode and the solid electrolyte for a rechargeable lithium metal battery that further includes a positive electrode. Optionally, the positive electrode includes elemental sulfur in a conductive matrix. The conformable polymer coated lithium metal electrode may be manufactured by a process involving electroplating lithium metal through a conformable polymer coated conductive substrate, for which the conformable polymer coated conductive substrate has been prepared by coating the conductive substrate in a solution of the conformable polymer followed by evaporating the solvent. Alternatively, a lithium metal electrode may be coated directly with conformable polymer. Rechargeable lithium batteries according to embodiments of the invention have improved cycle life and combustion resistance compared to lithium metal batteries manufactured by conventional methods.

Provided herein are energy storage devices. In some cases, the energy storage devices are capable of being transported on a vehicle and storing a large amount of energy. An energy storage device is provided comprising at least one liquid metal electrode, an energy storage capacity of at least about 1 MWh and a response time less than or equal to about 100 milliseconds (ms).

Electrochemical energy storage devices

Methods are proposed for manufacturing dendrite-resistant lithium metal electrodes suitable for incorporation into lithium metal batteries. In an embodiment, the method involves first electroplating a copper sheet onto a surface of a single crystal of silicon, the silicon being doped to form a p-type or an n-type semiconductor, and then further electroplating the copper sheet with lithium metal. The lithium-electroplated copper sheet thus manufactured provides a lithium electrode that is resistant to dendrite formation during cycling of lithium metal batteries when compared to conventionally manufactured lithium electrodes. Methods are further provided of manufacturing lithium sheets by directly electroplating lithium metal onto single crystals of doped silicon, the lithium sheets configured for incorporation into lithium metal electrodes that are resistant to dendrite formation during cycling of lithium metal batteries.

A method of and system for electrolytic production of reactive metals is presented. The method includes providing a molten oxide electrolytic cell including a container, an anode, and a current collector and disposing a molten oxide electrolyte within the container and in ion conducting contact with the anode and the current collector. The electrolyte includes a mixture of at least one alkaline earth oxide and at least one rare earth oxide. The method also includes providing a metal oxide feedstock including at least one target metal species into the molten oxide electrolyte and applying a current between the anode and the current collector, thereby reducing the target metal species to form at least one molten target metal in the container.

A rechargeable, self-heating aluminum-chalcogen battery is provided, with an aluminum or aluminum alloy negative electrode, a positive electrode of elemental chalcogen, and a mixture of chloride salts providing a molten salt electrolyte. The predominant chloride salt in the electrolyte is AlCl. Additional chloride salts are chosen from alkali metal chlorides. The cell operates at a modestly elevated temperatures, ranging from 90&#xb0; C. to 250&#xb0; C.

The electrolyte is configured to allow the cations of the calcium and alkali metal to be transferred from the negative electrode to the positive electrode during discharging and to be transferred from the positive electrode to the negative electrode during charging. The electrolyte exists as a liquid phase and one or both of the negative electrode and the positive electrode exists as liquid or partially liquid phases at operating temperatures of the electrochemical cell.

The invention relates to lithium ion battery, more particularly to a lithium nickel cobalt manganese oxide (Li(NiCoMn)O) composite material, including lithium nickel cobalt manganese oxide and a hydrophobic material coated on the surface of lithium nickel cobalt manganese oxide. The hydrophobic material coated on the surface of lithium nickel cobalt manganese oxide is insoluble in water, so that the lithium nickel cobalt manganese oxide composite material solves the problem that the batteries using conventional lithium nickel cobalt manganese oxide materials easily absorb water. A method for preparing the lithium nickel cobalt manganese oxide composite material is also disclosed.

The composite membrane includes a porous substrate having pores and a porosity from about 5 vol % to about 80 vol %, and a selective ion-conductive filler disposed at least partially within the pores. The filler includes an intercalation material.

The electrochemical cell also includes a bipolar faradaic membrane, disposed between the negative electrode and the positive electrode, having a first surface facing the negative electrode and a second surface facing the positive electrode. The bipolar faradaic membrane is configured to allow cations of the first active metal to pass through and to impede cations of the second active metal from transferring from the positive electrode to the negative electrode and is at least partially formed from a material having an electronic conductivity sufficient to drive faradaic reactions at the second surface with the cations of the positive electrode.

Electrochemical cell with bipolar faradaic membrane

Electrochemical cells having molten electrodes having an alkali metal provide receipt and delivery of power by transporting atoms of the alkali metal between electrode environments of disparate chemical potentials through an electrochemical pathway comprising a salt of the alkali metal. The chemical potential of the alkali metal is decreased when combined with one or more non-alkali metals, thus producing a voltage between an electrode comprising the molten alkali metal and the electrode comprising the combined alkali/non-alkali metals.
