Nickel‐Doped Co3O4@CoMoO4 Core–Shell Structures for Low Temperature Asymmetric Supercapacitors
Source abstract
Abstract
Abstract It is significant to explore the electrode materials for supercapacitors with high storage energy and long cycling stability. Herein, nanoporous Ni‐Co3O4@CoMoO4 composite is fabricated with excellent electrochemical performance. The as‐prepared sample delivers a specific capacity of 1212 C g−1 at 1 A g−1 and superior cycle performance (91.7% after 10 000 times charging and discharging). Several asymmetric supercapacitors (ASCs) are assembled using the synthesized products as cathode. They achieve an energy density of 102 Wh kg−1 at a power density of 2770 W kg−1. In addition, the devices present outstanding mechanical stability after multiple bending, demonstrating their potential application in the field of portable energy storage devices.
