Abstract
Photoresponsive batteries are an innovative technology that combines conversion and storage of solar energy, providing a potential solution for large-scale utilization of solar energy while reducing the reliance on traditional energy storage devices to meet the growing demand for energy. In search of more resource-saving alternatives to lithium-ion batteries, researchers are turning to zinc, which is abundant and environmentally friendly due to its recyclability. Zinc batteries offer high energy density and aqueous stability, making them a popular choice among researchers. This review summarizes the recent progress in photoresponsive zinc-based batteries. First, the photoresponsive zinc-based batteries are categorized into two groups: photoresponsive zinc-ion batteries and photoresponsive zinc-air batteries. The discussion then focuses on various photoelectrode designs, including some interesting strategies. Finally, the technical challenges associated with photoresponsive zinc-based batteries are summarized and discussed, and future research directions are proposed.
