英文摘要	Achieving long-term cyclic stability is an essential research target for advanced rechargeable aqueous zinc-ion batteries (ZIBs). However, the cyclic stability of the ZIBs cathode materials is severely limited due to the element dissolution, self-aggregation and phase change incorporated in Zn2+ uptake. In this work, Ti-doped NH4V4O10 is fabricated with robust bilayer structure which not only ensures the rapid and reversible Zn2+ (de)intercalation but also alleviate the accumulation of Zn ions. Besides, the impacts of the Ti doping on the morphology structure, electrochemical and the zinc-ion storage properties of NH4V4O10 are studied. Ti-doped NH4V4O10 nanobelts exhibit faster diffusion kinetic, higher electrochemical reversibility and better structure stability than pure NH4V4O10 sub-microbelts, leading to a capacity retention of 89.02% at 2 A g(-1)- after 2000 cycles, which is much higher than that of NH4V4O10 (62.86%).
