Researchers in Sweden have developed a battery using quinones, which occurs in photosynthesis, as the active material. It has the ability to absorb or emit hydrogen ions during charging and discharging. An acidic aqueous solution was used as an electrolyte. They demonstrated the battery can be easily charged using a solar cell without the help of advanced electronics and it is unaffected by ambient temperature. The battery retains properties such as capacity down to as low as -24°C… read more. TECHNICAL ARTICLE
