A room-temperature rechargeable dual-plating lithium-aluminium battery.

A room-temperature rechargeable dual-plating lithium-aluminium battery with a high theoretical energy density is presented. Based on the aluminium plating/stripping and lithium stripping/plating occurring at the cathode and anode sides, respectively, this lithium-aluminium battery displays an output voltage of 1.75 V (theoretically, about 2.0 V). Moreover, a "cathode-free" lithium-aluminium battery is designed, which displays good stability.
