Description
Technical Field
The invention belongs to the technical field of batteries, and particularly relates to an ammonium vanadate electrode material, a preparation method and application thereof in a water-based zinc ion battery.
Background
Lithium ion batteries have become a major topic in the field of energy storage devices for decades due to their excellent energy density and long cycle life. Despite these advantages, the scarcity of lithium resources and the flammability of organic electrolyte greatly limit the application of lithium ion batteries. Therefore, an aqueous zinc ion battery has been proposed. The water-based zinc ion battery has low cost and high theoretical capacity (5585 mAh cm) -3 ) And negative oxidation-reduction potential, etc.However, as a facility for hopefully changing lithium ion batteries, zinc ion batteries are still in the original state. The electrostatic repulsion of zinc ions and the low potential window hinder their reversible ability. Thus, the preparation of a suitable positive electrode material to increase the diffusion rate of zinc ions, reversible intercalation of zinc ions, is an effective method. The vanadium-based material is undoubtedly a cathode material of the water-based zinc ion battery due to the multi-layer lattice structure and the polyvalent state of vanadium. For vanadium-based materials, it has good electrochemical properties at high current densities, but poor cycling properties at low current densities, mainly due to electrostatic interactions and intrinsic dissolution of vanadium. Electrostatic interactions between zinc ions and the vanadium oxide layer will lead to slow ion diffusion, producing irreversible zinc-vanadium byproducts. The intrinsic dissolution of vanadium is caused by the erosion of water by the water electrolyte, which leads to collapse of the layered structure and capacity decay. Therefore, increasing the bond energy between the layered lattices is an effective method for solving the above-mentioned problems.
For (NH) 4 ) 2 V 6 O 16 In the prior art, ammonium metavanadate is generally used as a precursor and is dissolved in water to be subjected to hydrothermal treatment, and the method cannot ensure that bound water exists in the hydrothermal treatment. On the basis of this, doping of sodium ions is introduced, and the doping of sodium ions is inserted into the vanadium oxide layer, so that the interface binding energy is improved, and the stability of bound water in the crystal structure is also improved. Sodium intercalation (NH) formed in one step 4 ) 2 V 6 O 16 The (NNVO) has simple experimental steps and improves the electrochemical performance of the ammonium vanadate as a cathode material of the water-based zinc ion battery. Therefore, it is urgently required to design a new preparation method of ammonium vanadate electrode material.
Through the above analysis, the problems and defects existing in the prior art are as follows:
(1) The scarcity of lithium resources and the flammability of organic electrolyte greatly limit the application of lithium ion batteries; the use of zinc ion batteries is still in its original state, and electrostatic repulsion of zinc ions and a low potential window hinder its reversibility.
(2) For vanadium-based materials, good electrochemical performance is achieved at high current densities; however, vanadium-based materials have poor cycling performance at low current densities due to electrostatic interactions and inherent dissolution of vanadium.
(3) Electrostatic interactions between zinc ions and the vanadium oxide layer will cause slow ion diffusion, producing irreversible zinc-vanadium byproducts; erosion of water by water electrolysis causes an intrinsic dissolution of vanadium, which leads to collapse of the layered structure and capacity decay.
