The present disclosure provides an energy storage device comprising at least one electrochemical cell comprising a negative current collector, a negative electrode in electrical communication with the negative current collector, an electrolyte in electrical communication with the negative electrode, a positive current collector, and a positive electrode in electrical communication with the positive current collector and electrolyte. The positive electrode comprises a material that is solid at the operating temperature of the energy storage device.

Molten salt battery with solid metal cathode

The disclosure provides electrochemical batteries, electrochemical battery housings and methods for assembling electrochemical batteries. The battery housing can include a container, a container lid assembly and an electrical conductor. The container can include a cavity that extends into the container from a cavity aperture. The lid assembly can seal the cavity, and can include an electrically conductive container lid and an electrically conductive flange. The container lid can cover the cavity aperture and can include a conductor aperture that extends through the container lid. The flange can cover the conductor aperture and can be electrically isolated from the container lid. The conductor can be connected to the flange and can extend through the conductor aperture into the cavity. The conductor can be electrically isolated from the container lid.

Electrochemical energy storage devices and housings

The present disclosure provides an energy storage device comprising at least one electrochemical cell comprising a negative current collector, a negative electrode in electrical communication with the negative current collector, an electrolyte in electrical communication with the negative electrode, a positive electrode in electrical communication with the electrolyte and a positive current collector in electrical communication with the positive electrode. The negative electrode comprises an alkali metal. Upon discharge, the electrolyte provides charged species of the alkali metal. The positive electrode can include a Group IIIA, IVA, VA and VIA of the periodic table of the elements, or a transition metal (e.g., Group 12 element).
