Abstract
- • Perovskite-type SrVO 3 was prepared by a facile sol–gel route. • The SrVO 3 was firstly investigated as cathode material for aqueous zinc-ion batteries. • The SrVO 3 exhibits rate performance with a capacity retention of 79 % for 3000 cycles at a current density of 2000 mA g−1. Aqueous Zinc ion batteries (AZIBs) is well considered as a potential candidate with green, safety and low cost for large-scale grid storage. Perovskite oxide SrVO 3 can be used as the cathode material for AZIBs due to its high electrically conductive. Therefore, the SrVO 3 as a novel cathode material by sol–gel route was prepared to investigate the electrochemical performance. The SrVO 3 exhibits outstanding rate capability with high reversible capacities of 142.7 mA h g−1 at 200 mA g−1, 134.9 mA h g−1 at 300 mA g−1, and 105.3 mA h g−1 at 2000 mA g−1 are ascribed to the fast diffusion reaction kinetics. Moreover, the cycling performance of SrVO 3 was delivered with capacity retention of 79 % after 3000 cycles at a current density of 2000 mA g−1 in the 0.4–1.8 V voltage window. This work provides a new prospect for the development of perovskite-type cathode materials for AZIBs. [ABSTRACT FROM AUTHOR]
