Layered barium vanadate nanobelts for high-performance aqueous zinc-ion batteries
Abstract Aqueous zinc-ion batteries (ZIBs) are deemed as the idea option for large-scale energy storage systems owing to many alluring merits including low manufacture cost, environmental friendliness, and high operations safety. However, to develop high-performance cathode is still significant for practical application of ZIBs. Herein, $ Ba_{0.23} $$ V_{2} $$ O_{5} $·1.$ 1H_{2} $O (BaVO) nanobelts were fabricated as cathode materials of ZIBs by a typical hydrothermal synthesis method. Benefiting from the increased interlayer distance of 1.31 nm by $ Ba^{2+} $ and $ H_{2} $O pre-intercalated, the obtained BaVO nanobelts showed an excellent initial discharge capacity of 378 mAh·$ g^{−1} $ at 0.1 A·$ g^{−1} $, a great rate performance (e.g., 172 mAh·$ g^{−1} $ at 5 A·$ g^{−1} $), and a superior capacity retention (93% after 2000 cycles at 5 A·$ g^{−1} $)..
