چکیده
Design and synthesis of new and high-performance electrode materials are the tasks of scientists to respond to the increasing demand for efficient renewable energy storage devices. Herein, we developed a spinel nickel-manganese-cobalt ternary oxide (NMCO) spheres by a facile approach with a hollow-interior nanoporous shell possessing a high specific surface area of 67 m2 g-1 and pore size distribution of about 8 nm as a high-performance electrode material for supercapacitor applications. This electrode delivers ultrahigh specific capacitance of 1372 F g−1 at 2 A g−1 (4.1 F cm−2 at 6 mA cm−2) with remarkable rate capability of 55% after increasing the current density from 2 A g−1 (6 mA cm−2) to 60 A g−1 (180 mA cm−2), excellent cycling stability of 91.2% after 10000 continues charge/discharge cycles at 15 mA cm−2, and maximum energy density of 38.6 Wh kg−1. This work sheds further light on the design and development of high-performance electrode materials not only for energy storage applications but also for other electronic devices.
