Energy storage devices play a crucial role in various applications, such as powering electronics, power backup for homes and businesses, and support for the integration of renewable energy sources into electrical grid applications. Electrode materials for energy storage devices are preferred to have a flexible nature, conductive, better capacity, and low‐toxicity. Currently, using Gallium based liquid metal alloys, such as Eutectic Gallium‐Indium (EGaIn), Eutectic Gallium‐Tin (EGaSn), and Eutectic Gallium‐Indium‐Tin (EGaInSn), as electrode materials play very important role in energy storage devices. These liquid metals have some interesting properties with a self‐healing nature, high mechanical stability, compatibility with various materials, fluidity, low young’s modulus, high electrical and thermal conductivity. Those properties have made it suitable to be used in various energy storage devices. In this mini review, we have concisely described the advantages and challenges of using liquid metal as electrode materials for various energy storage devices.
