Recent Advances in the Research of Photo‐Assisted Lithium‐Based Rechargeable Batteries

Abstract The application of solar energy is crucial for alleviating the energy crisis and achieving sustainable development. In recent years, photo‐assisted rechargeable batteries have attracted researchers because they can directly convert and store solar energy in the batteries. And it also can be used like a normal battery without light illumination. Photo‐assisted lithium‐based batteries have received more attention than other energy storage systems due to their higher energy density and relatively mature development. This Review focuses on the design of various photo‐assisted lithium‐based batteries including Li‐ion, Li‐S, Li‐O 2 , Li‐CO 2 and Li‐I batteries, as well as the working mechanism of photoelectrodes in these battery systems. The basic understanding and challenge of photo‐assisted lithium‐based batteries are also discussed. At last, perspectives for the photoelectrode development are provided in the summary to advance photo‐assisted energy storage systems.
