Overview

Experimental study demonstrates enhanced energy density in multimetallic selenide supercapacitors, indicating a viable pathway for high-capacity energy storage devices.

Key Points

To synthesize a three-dimensional nickel-cobalt-molybdenum selenide electrode using a hydrothermal method to improve the energy density and cycling stability of supercapacitors.
Fabricated nickel/cobalt/molybdenum-based metal nanocomposite selenide (NCMS) electrodes via hydrothermal synthesis.
Assembled the material into an asymmetric supercapacitor configuration and analyzed electrochemical kinetics and charge transfer resistance.
The optimized NCMS electrode achieved an areal capacitance of 16.24 F·cm–2 at 5 mA·cm–2 and 7.24 F·cm–2 at 50 mA·cm–2, retaining 97.7% capacitance after 10,000 cycles.
The asymmetric supercapacitor device delivered areal capacitances of 0.89 F·cm–2 at 5 mA·cm–2 and 0.51 F·cm–2 at 50 mA·cm–2, with a maximum surface energy density of 0.316 mWh·cm–2 and power density of 3.969 mW·cm–2.
