Superior electrochemical performances of highly porous bismuth oxyhalides decorated lemon peel derived activated carbon electrode materials for solid state asymmetric and symmetric supercapattery devices

). Compared to the ASC device, the SSC device could power a 2 V red LED for 555 s and a 3.7 V electric motor fan for 122 s. Hence, the prepared BOB-LPDAC nanocomposite may serve as an excellent electrode material for solid-state symmetric supercapattery applications.
