摘要
Aqueous zinc-ion batteries (ZIBs) have attracted extensive attentions due to their high capacity and low-cost. Yet the long-term cycling performance is needed to be further optimized to meet the demand of grid-scale energy storage application. Herein, we introduce a new strategy to improve the cycling performance of aqueous ZIBs by the construction of biphase composites, as an example of V2O5/NaV6O15. It demonstrates excellent long-term cycling stability, with a high capacity of 164 mA h g−1 after 2000 cycles at 5 A g−1 and 116.7 mA h g−1 after 4000 cycles at 10 A g−1.
