External field–assisted batteries toward performance improvement
Wanwan Wang, Yi‐Chun Lu
Abstract
Abstract 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.
