A high energy density all solid-state tungsten–air battery†
Abstract
An all solid-state tungsten–air battery is reported here, which is based on a new metal–air chemistry, featuring decoupled design of electrodes and energy storage. Benefited from higher specific density and better redox kinetics of tungsten, the new tungsten–air battery exhibits roughly higher energy density (W h L−1) than the previously reported iron–air battery.
