Recently, researchers from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences have made new progress in the study of membrane materials for zinc-based batteries
.
Through the structural design of the membrane material, the team realized the uniform zinc deposition process under the conditions of high areal capacity and high current density, and conducted a detailed study and discussion on the mechanism of the membrane structure regulating the zinc deposition process
The rapid development of renewable energy has promoted the development and research of high energy density energy storage devices based on zinc chemistry
.
Zinc secondary batteries have the advantages of low cost, high safety, and high energy density, and have good compatibility with aqueous electrolytes, and have good application prospects in the field of electrochemical energy storage
In the research, the team developed a new type of polymer film with orderly undulating stripes on the surface-Turing film, which can achieve uniform zinc deposition with high surface capacity and high current density
.
In the design of Turing membrane, the peaks and troughs of the stripes on the membrane surface can be controlled by the carrier flux in the micro area, thereby effectively adjusting the distribution of zincate and providing more zinc deposition space
