The key of Zn2+ transfer kinetics in zinc metal batteries

Abstract

Interface chemistry inevitably affects Zn dendrite formation and interfacial kinetics, which pose serious challenges in zinc metal batteries (ZMBs). In the December issue of Chem, Guo et al. identified that Zn²⁺ transport in the solid electrolyte interphases (SEIs) is the rate-limiting step of Zn²⁺ transfer kinetics in typical ZMBs and designed a SEI comprising Zn₃N₂ species, thereby overcoming the above-mentioned issues.
