Summary:
Iowa State University researchers have developed a new battery chemistry suitable for secondary energy storage, including storage of electricity produced by renewable energy sources such as solar and wind generation.  These batteries offer comparable energy density to lithium-based batteries, but feature a liquid metal anode, avoiding the dendrite formation and related safety issues of lithium batteries.

Development Stage:
Description:
Iowa State University researchers have recently developed a new battery chemistry which combines a copper metal cathode with an alkali metal solution at the anode.  The metal solution can be kept in the liquid state at lower temperatures than other molten salt batteries (such as sodium-sulfur and sodium-nickel batteries), improving system efficiency and lowering the cost of containment materials.  The batteries utilize a solid alkali ion conducting separator and aqueous catholytes of the alkali metal salts.

Advantage:
• Abundant and cheap anode materials
• Lower temperature operation and less corrosive than other sodium-based batteries
• Safe operation
Application:
Secondary energy storage
