Abstract Aqueous zinc-metal batteries are promising candidates for sustainable energy storage; but their practical viability is severely limited by poor cryogenic performance caused by kinetic sluggishness and interfacial instability. Here we show a strategy for low-temperature ZMBs based on tailoring the Zn2+ solvation environment by engineering the dielectric constant (ε).

Electron displacement polarization of high-dielectric constant fiber separators enhances interface stability - Nature Communications

|
By Tao Zhang, Xiaoqing Zhu, Keith Gordon, Guiyin Xu
| Nature Verified
Abstract The electrostatic effects of separators under the internal electric field are often overlooked, leading to the unreliability of traditional theoretical models. Here we introduce the dielectric constant as a descriptor and develop a high dielectric constant fiber separator primarily composed of phosphorylated cellulose.
