摘要：With the ever-increasing demands of grid-scale energy storage,aqueous zinc-ion batteries(ZIBs)have garnered increasing attention around the ***,limited Zn^(2+)host materials have hindered the commercialization of ***,Mo-V oxides with different phase structures(orth-,tri-,and tetra-MoVO)were precisely constructed to develop phase-dependent Mo-V oxide cathodes for Zn^(2+)storage in *** open frameworks and varied tunnel structures formed a favorable alternative for achieving suitable Zn^(2+)diffusion *** optimized phase engineering,the high specific capacity of approximately 400 mA h g^(−1) and excellent cyclic stability of 1000 cycles were achieved with orth-MoVO as the *** large amount of six-and seven-member rings in the orth-MoVO phase,which allow for alternative Zn^(2+)insertion,play a vital role in hosting Zn^(2+)ions *** proposed phase engineering strategy provides a new approach toward cathode design in ZIBs.
