A research team from the School of Materials Science and Engineering at Beijing University of Chemical Technology recently published a study on aqueous zinc-ion batteries in Advanced Functional Materials.
They introduced a zinc-philic, hydrophobic copper-modified Ti3C2Cl2 MXENE material as a protective coating for the zinc metal anode of aqueous zinc-ion batteries, which significantly improved the stability and reversibility of the zinc anode.
*It is pointed out that aqueous zinc-ion batteries have the advantages of low cost, high safety and high specific energy, and have broad application prospects in the field of large-scale energy storage.
However, the stability and durability of the metal zinc anode is a key technical bottleneck.
To solve this problem, the research team prepared a copper-modified Ti3C2Cl2Mxene material with high zinc philophilic and hydrophobic properties by molten salt etching method, and applied it to the zinc anode as a protective coating.
The results show that the Cu-MXENE coated zinc anode exhibits a cycle life of more than 1000 hours, a polarization potential of less than 120 mV at a current density of 10 mA cm-2, and a coulombic efficiency of more than 6% for 1100 cycles.
This breakthrough research result provides important technical support for the stability and reliability of aqueous zinc-ion batteries.
It is pointed out that the Cu-MXENE coating can also be extended to the metal anode protection of other aqueous batteries, which has a broad application prospect.
This research result has brought new enlightenment to the technological innovation and industrial development in the field of aqueous zinc-ion batteries, and has important scientific significance and application value.
Through the release of this research result, the research team will continue to explore the potential application value in the field of aqueous zinc-ion batteries, and make greater contributions to the technological progress and industrial development in the field of new energy.
