Description
Summary:We propose an innovative solar photothemal battery technology to develop all-solid-state lithium-air batteries operating at ultra-low temperatures where a plasmonic air electrode can efficently harvest solar energy and convert it into heat, enabling efficient charge storage and transmission in electrolyte/electrode materials. Such batteries demonstrate a high discharge capacity (∼3600 mA h g −1 ) at −73 °C and record-cycle life both at −73 °C and room temperature. Plasmon-enhanced solar photothemal battery (STPB) technology allows all-solid-state lithium-air batteries to operate at temperatures as low as −73 °C.
