Description
Technical Field
The invention relates to the technical field of zinc ion batteries, in particular to a zinc ion battery electrolyte modifier and a preparation method and application thereof.
Background
The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.
With the rapid development of microelectronic information technology, the demands of electric vehicles, large-scale energy storage and the like are increasing day by day, and the development of secondary energy storage chargeable and dischargeable batteries with high performance and large capacity is urgent based on the urgent demands of current green, high-efficiency and practical energy storage materials. The zinc ion secondary battery has the advantages of high safety, low cost, environmental friendliness, low oxidation-reduction potential, high water decomposition overpotential, high theoretical specific capacity and the like. Secondly, the aqueous electrolyte has significant advantages of low cost, high safety, large ionic conductivity, and the like, compared with the organic electrolyte. And thus have received extensive research and attention.
The current zinc ion secondary battery has higher specific capacity and low cost, but a dendritic morphology can be formed due to uneven current and ion distribution in the charging and discharging process, so that the practical application of the zinc ion secondary battery is hindered. Zinc dendrites often form unstable solid electrolyte interfaces and can even penetrate the separator causing serious safety concerns due to their high chemical reactivity. And the zinc dendrite may be broken at the contact part with the electrode during the charging and discharging process to form dead zinc, which results in low coulombic efficiency. The unstable current density and ion concentration at the dendrites can further exacerbate dendrite growth, ultimately leading to poor rechargeable battery life. Therefore, suppression of zinc dendrites is one of the prerequisites for practical use.
Although the composite electrode composed of the MXene film and the metal zinc can inhibit zinc dendrites, the cycling stability of the battery is poor, and how to inhibit the zinc dendrites and improve the cycling stability of the battery becomes a technical problem to be solved urgently.
