facile low temperature (90 °C) two-step hydrothermal technique without surfactant or template. The special hydrangea-like structure and large specific surface area (74.8 m2/g) provided plenty of electro active sites which were beneficial to superior pseudocapacitive performance of NiCo2S4. The supercapacitors performance of
NiCo2S4 was investigated by a three-electrode system. NiCo2S4 exhibited high specific capacitance with 1475 F g−1 at a current density of 3 A g−1, and a fairly high rate capacity with 1152 F g−1 at 20 A g−1. These results indicate that low temperature hydrothermal is a very promising method to prepare electrode materials for
supercapacitors.
