英文摘要	The development of cathode materials with high Li storage capacity and fast Li-ion diffusion kinetics is considered to be a promising way to extend the energy and power densities of Li-ion batteries (LIBs). As potential high-capacity cathode materials for LIBs, polyoxometalates (POMs) suffer greatly from inherent drawbacks. Therefore, another possibility for the application of POMs in LIBs is shown, which is to transform POMs into relevant 3D porous Li-containing oxides. Here, a unique 3D porous gamma-LiV2O5 film is successfully prepared by combining the electrostatic spray deposition technique and the POM as a precursor. Outstanding high capacity with stable cycling performance and excellent rate capability is realized based on 3D porous nanostructure and thin-film morphology, which effectively facilitate the transport of both lithium ion and electron. Moreover, this work demonstrates the feasibility of achieving high-performance metal oxide cathode by the transformation of POMs and also shows the superiority of gamma-phase over alpha-phase as a starting cathode material in LIBs as well.
