Bimetallic sulfide based on various carbon materials for supercapacitors

The NiCo 2 S 4 /C hybrid material was successfully prepared by a simple one-step hydrothermal method. Carbon composite increases the specific surface area of and provides more ion attachment points during electrochemical process. Conducive to transportation transfer, composition carbon greatly improves conductivity material. Electric double-layer capacitor materials can accept transferred ions faster than pseudocapacitor materials, enable better adapt intensity current changes. Compared with single or pseudocapacitance material, it has higher capacity. This discovery is great significance research pseudocapacitive supercapacitors.
