Dalian Institute of Chemical Technology has prepared high-performance alkaline zinc iron flow battery ion conductive membrane

Recently, the team of Xianfeng Li, a researcher in the Energy Storage Technology Research Department of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and Zhizhang Yuan, an associate researcher, have made progress in alkaline zinc iron flow battery ion conduction membranes, and prepared high-performance alkaline zinc iron flow battery ion conduction.
Membrane
.

Energy storage technology is the key technical support for building a clean, low-carbon, safe and efficient energy system
.

In recent years, the team has used the structural design of ion-conducting membranes to control the charging characteristics of ion-conducting membranes (Nat.
Commun.
, 2018), thermal conductivity (Angew.
Chem.
Int.
Ed.
, 2020), and mechanical strength (iScience , 2018), etc.
, achieved the uniform deposition of zinc and greatly improved the cycle life of the battery
.

In this study, in order to increase the working current density of alkaline zinc-iron flow batteries, the research team introduced hydrotalcite nanomaterials (LDHs) into alkaline zinc-iron flow batteries, and designed and prepared high-performance hydrotalcite composite ion-conducting membranes.
