Rechargeable batteries are essential for the increased demand for energy storage technologies due to their ability to adapt intermittent renewable energies into electric devices, such as electric vehicles. To boost the battery performance, applying external fields to assist the electrochemical process has been developed and exhibits significant merits in energy efficiency and cycle stability enhancement. This perspective focuses on recent advances in the development of external field–assisted battery technologies, including photo‐assisted, magnetic field–assisted, sound field–assisted, and multiple field–assisted. The working mechanisms of external field–assisted batteries and their challenges and opportunities are highlighted. Applying external fields, including light, magnetic, and sound, to energy storage systems provides a new direction to enhance the performance of rechargeable batteries. The working mechanism and characteristics of different external field–assisted batteries are emphasized in this Perspective. In addition, the key challenges and perspectives for each external field–assisted battery are highlighted.
