Abstract
An alkali metal battery has an alkali metal anode such as lithium in an organic anolyte and a cathode in an aqueous catholyte. An ion conductive diaphragm allows ions to migrate between the anolyte and the catholyte while limiting the transport of water from the catholyte to the anolyte. In a preferred embodiment, the ion conductive diaphragm is nonporous so that there is no transport of water ion to the anolyte. The battery is particularly useful for long durations of up to a week or longer in seawater.
