摘要：

A new type of Zn2VO4/ZnO/carbon composite (three-dimensional porous architecture) was firstly fabricated on a Ni-metal foam substrate thorough a facile electrostatic spray deposition (ESD) method followed by a calcination process. As a binder-free electrode in high performance lithium-ion batteries (LIBs), the composite electrode displays an outstanding long cycling performance, and it exhibits a high specific capacity of 930.8 mAh g(-1) at 2 A g(-1) even after 800 cycles without any capacity fading. And, the composite also shows a good rate performance with specific charge capacities of 742.1, 658.7, 804.9, 567.3 and 519.3 mAh g(-1) at 0.1, 2, 5, 10 and 12 A g(-1) respectively.
