The hollow core-shell CuCo2O4 spheres are synthesized by coating glucose-based carbon template with the metal precursors (copper nitrate and cobalt nitrate) through a solvothermal method, and followed by calcination process leading to Ostwald ripening. The hollow core-shell structure is very suitable for enhancing electrochemical performance by offering high surface area, high pore volume, and well-developed interior spaces accommodating volume variation. Thus, the morphology composed of hollow core-hsell for CuCo2O4 spheres enables to improve the rate capability and sustain electrochemical stability. The hollow core-shell CuCo2O4 anode delivers high specific capacity of 664 mAh g-1 at 500 mA g-1 compared to conventional CuCo2O4 anodes. |
