Hydrogen has important values in industrial manufacture, medical health care, and diverse energy application areas. Among the many possible approaches, convenient and safe hydrogen production from water electrolysis has always been a preferred in situ hydrogen supply technology. So far, many of the electrodes thus involved are based on rigid metals or conductive items which may encounter inconvenience or insufficiency sometimes. To achieve targeted release of hydrogen, appropriate administration of suitable flexible hydrogen evolution electrodes is the key. In recent years, gallium-based liquid metals have emerged in the field of flexible and biological electrodes. Starting from this point, liquid metal is proposed here as a transformable amorphous electrode for hydrogen evolution in electrolytic water which may help mold new conceptual electrolysis and energy utilization ways.
