摘要

In this communication, a simple solar rechargeable battery based on the sodium ion storage mechanism with Fe-2(MoO4)(3) microspheres as anode materials is proposed for the first time. The battery can be photo-charged under solar irradiation, and discharged reversibly in the dark. Therefore, photon-electron conversion, and energy storage and release based on reversible sodium ion insertion and extraction can be realized in the solar rechargeable battery.
