Abstract
- As a widely used electrode material, carbon cloth possesses the advantages of a stable self-supporting structure and fast electron conduction rate. Sodium vanadate has gradually attracted the attention of researchers owing to its unique layered tunnel-like structure. In this work, in-situ growth of NaV 6 O 15 on carbon fiber with a 3D porous tunnel-like structure for cathode material of aqueous zinc ion batteries is reported. NaV 6 O 15 nanorods are uniformly dispersed on the surface of carbon cloth fibers and coated perfectly, which intertwined to form rich 3D porous tunnels. The as-prepared NaV 6 O 15 @C has a reversible capacity of 487.7 mAh·g−1 at 0.1 A·g−1, which is 2.6 times that of pure NaV 6 O 15 -A. The coulomb efficiency (CE) is always maintained at 100 %, which proposed a scheme for the design of higher capacity cathode materials. • Carbon cloth coated by NaV 6 O 15 nanorods was designed for zinc ion battery cathode. • NaV 6 O 15 @C shows a 3D tunnel structure and provides a rich adsorption site. • NaV 6 O 15 @C has a high specific capacity, which is 2.6 times that of pure NaV 6 O 15.
