ZnO/C nanocomposite microspheres with capsule structure for anode materials of lithium ion batteries
Source abstract
Abstract
Abstract Well-designed nanostructures are very critical to the lithium-storage performance of electrode materials. To enhance the electrochemical performance of zinc oxide anode materials, a capsule structure, composed of carbon shell and its encapsulating ZnO microsphere, is designed. This capsule structured ZnO/C nanocomposite microspheres are prepared by a sol-gel method combined with two calcination processes. The carbon capsule shows great advantages of enhancing the structural stability of active material, reducing the formation of solid electrolyte interface (SEI) layer, and improving the conductivity of electrode. These factors are quite beneficial to the improvement of cycling stability, initial coulombic efficiency and rate capability. Consequently, capsule structured ZnO/C nanocomposite microspheres deliver an initial charge capacity of 790 mA h g−1, an initial coulombic efficiency of 71%, and a reversible capacity retention of 63% after 100 cycles, all of which are higher than those of pure ZnO microspheres. These results suggest that the design of carbon encapsulated ZnO microsphere is quite effective for enhancing the lithium-storage properties and can also show general significance for developing high-performance electrode materials.
