Abstract

An alkali metal-cathode solution storage battery includes an alkali metal anode including at least one alkali metal, a cathode including copper metal, and an alkali ion conducting electrolyte/separator separating the anode and cathode. An anode side electrolyte is between the anode and the separator, and a cathode side electrolyte is between the cathode and the separator. The cathode side electrolyte is selected to have capacity to dissolve metal ions from the alkali metal and electron conducting materials. An ion exchange reaction occurs during operation of the battery within the cathode side electrolyte. The battery can be operated at low temperature (i.e., < 100 degrees C). and provide high specific energy density. The battery can be a planar battery arrangement.
