Rational design of bi‐phase CaV2O6/NaV6O15 cathode materials for long‐life aqueous zinc batteries
Abstract Vanadium‐based compounds with various crystal structures are highly promising cathode materials for aqueous zinc‐based batteries. However, their further development is limited due to the low electrical conductivity, slow zinc ion diffusion, and weak structural stability. It is a feasible st...

| description | Abstract Vanadium‐based compounds with various crystal structures are highly promising cathode materials for aqueous zinc‐based batteries. However, their further development is limited due to the low electrical conductivity, slow zinc ion diffusion, and weak structural stability. It is a feasible strategy to resolve above mentioned issues through surface modification. Herein, we design bi‐phase coexisting CaV2O6/NaV6O15 nanobelt structures with abundant interfaces, which provide more reactive sites than single‐phase ones. The samples as the electrode materials deliver a specific capacity of 312 mAh g−1 at 5 A g−1 after 2000 cycles. They still keep a capacity of 231 mAh g−1 at 10 A g−1 with a cycle life of 6500 times. |
