One-Pot Synthesis of Glucose-Derived Carbon Coated Ni(3)S(2) Nanowires as a Battery-Type Electrode for High Performance Supercapacitors

We report a novel Ni(3)S(2) carbon coated (denoted as NCC) rod-like structure prepared by a facile one-pot hydrothermal method and employ it as a binder free electrode in supercapacitor. We coated carbon with glucose as carbon source on the surface of samples and investigated the suitable glucose concentration. The as-obtained NCC rod-like structure demonstrated great performance with a huge specific capacity of 657 C g(−1) at 1 A g(−1), preeminent rate capability of 87.7% retention, the current density varying to 10 A g(−1), and great cycling stability of 76.7% of its original value through 3500 cycles, which is superior to the properties of bare Ni(3)S(2). The result presents a facile, general, viable strategy to constructing a high-performance material for the supercapacitor applications.
