Researchers have unveiled a novel air-chargeable battery for a sustainable power solution. This technology traps the oxygen from the environment to drive the charging process for energy storage and is a step towards a carbon-neutral future. In a world racing toward renewable energy solutions, a photo-assisted battery offers great promise as they combine the best of two worlds-- the light-capturing capability of solar cells and the robust energy storage of conventional batteries. Generally, solar panels convert sunlight into electricity, but they rely on separate battery systems to store the energy for later use. In contrast, photo-assisted batteries merge these functions into a single device, creating a seamless synergy between solar energy conversion and storage.
