Abstract
1D nanorods of the layered material K(2)V(6)O(16)2.7H(2)O (KVO) are implemented for the first time as cathode materials in secondary aqueous rechargeable Zn-ion batteries (ARZIBs) and exhibit excellent electrochemical Zn storage properties. This cathode material delivers a reversible capacity of 296 mA h g(-1) over 100 cycles. At current densities of 1000, 3000, and 5000 mA g(-1) for 700 cycles, the electrode displays reversible capacities of 223, 177, and 138 mA h g(-1), for approximately 170, 300, and 230 cycles, respectively. In addition to these properties, it withstands over 500 cycles at an applied current density of 6000 mA g(-1) with nearly 82% capacity retention. The battery offers a specific energy of 128 Wh kg(-1) at a specific power of 5760 W kg(-1), revealing the advantages of the material in an eco-friendly atmosphere.
