Abstract

The Lith′ing Daylights: The direct chemical reaction between lithium and water is employed as a controllable electrochemical reaction in a lithium–water cell to generate H2 gas. The hydrogen generation can be easily controlled by adjusting the current density of the external circuit or discharge time. Lithium-metal production using solar energy and controllable hydrogen generation from such electrochemical cells may provide a new avenue for sustainable hydrogen generation.
