Micro-Spatial Hydrothermal Preparation of Nitrogen-doped Carbon/NiCo2S4 Electrode Material for Supercapacitors

Reasonable combination of carbon and pseudocapacitive material in a composite electrode can produce a high-performance supercapacitor. However, the nano-structured pseudocapacitive materials tend to assemble randomly into microscale bulky forms during the preparation of composite electrode materials, which suffer from a low specific surface area and a mechanically weak structure, resulting in poor electrochemical performance. In this article, a...
