Abstract
Irreversibility of the cycling process promotes electrode failure, and the primary prerequisite for improving discharge–charge reversibility is to improve structural stability. Herein, we employ a strategy of in situ growth of MOF-derived V2O3 on carbon cloth, which improves the cycling performance of Zn/V2O3-CC cell. As expected, a reversible discharge capacity of 203 mAh g−1 was also demonstrated after 5000 cycles at 1 A g−1, counterpart of 100% high capacity retention. Moreover, a maximum discharge capacity of 447 mAh g−1 was delivered at 0.1 A g−1. The enhanced cycling stability and high discharge specific capacity are mainly ascribed to the stable cathode structure and oxygen vacancy defects. This work not only reveals the root cause of the long cycling performance exhibited by V2O3-CC but also opens up an avenue for the construction of advanced electrode materials.
