- Abstract
(2, 3-DN)0.23V2O5·0.22H2O (DN = dinaphthoquinone) nanosheets with rich oxygen vacancies (abbreviated as (2, 3-DN)-VO) were synthesized by a facile one-step solvothermal method. Rietveld refinement illustrates the successful intercalation of 2, 3-DN into the layered vanadium oxide. (2, 3-DN)-VO can deliver a high specific capacity of 440 mAh g−1 at 0.1 A g−1 with a capacity retention of 92.6% over 2300 discharge/charge cycles at 10 A g −1 when used as zinc-ion battery cathode. It benefits from the dual-activity of naphthoquinone and vanadium oxide. Meanwhile, the encapsulation of naphthoquinone into the interlayer channel of vanadium oxide not only can expand the interstitial spacing for the diffusion of Zn2+, but also prevent the dissolution of the organic species into the electrolyte.
