An Azo‐Based Electrode for All‐Around High‐Performance Flexible Supercapacitors

The photo-rechargeable supercapacitor enables the self-powering of flexible wearable electronics. However, electronics require supercapacitors not only with excellent flexibility but also high energy density. P-diaminoazobenzene (P-Azo) as a new type organic electrode material NN is directly connected to benzene ring and forms large π-conjugated system, which makes it have lower lowest unoccupied molecular orbital (LUMO) level, beneficial transfer electrons, increases conductivity molecules. In addition, can realize two P-Azo higher Asymmetric are fabricated by assembling P-Azo, activated carbon, an adhesive electrolyte, 425.2 mW h cm−2 (55.19 Wh kg−1) density at power 80 (10.38 W kg−1), 90.7% capacitance retention after 000 cycles bending. this work, perovskite submodules coupled prepare achieve 7% overall energy-conversion efficiency. Therefore, paves practical route for powering future
