A stable discharge voltage is shown with high areal energy storage capacity of 180 W h cm-2 by choosing iodide/polysulfide as the pair of active materials matched with permeable porous electrodes. The solar rechargeable battery system offers a higher round-trip efficiency and potential cost savings on fabrication compared to individual devices.
