In this study, a three-dimensional Ni3S2/MnS2 composite was prepared using hydrothermal method and showed promising application potential in energy storage. The composite exhibited good specific capacity and high cycle retention in supercapacitor, indicating its suitability for long-term use.
In this work, three-dimensional Ni3S2/MnS2 composite is prepared by in-situ vulcanization using hydrothermal method and applies to supercapacitor. The as-prepared Ni3S2/MnS2 composite shows good specific capacity (383.4 mAh/g at 1 A/g) and high cycle retention of 90.6% after 10,000 cycles at 5 A/g. The specific energy of assembled hybrid supercapacitor can reach 52.7 Wh/kg at the specific power of 849.3 W/kg. The results indicate that the Ni3S2/MnS2 composite obtained in this work has good application potential in energy storage.
