Composite Solid Electrolytes: Facilitating Interfacial Stability Via Bilayer Heterostructure Solid Electrolyte Toward High‐energy, Safe and Adaptable Lithium Batteries (Adv. Energy Mater. 31/2020)

In article number 2000709, Qiuwei Shi, Hongzhi Wang and co-workers propose a composite solid electrolyte with bilayer heterostructure, which is designed to facilitate interfacial stability and electrochemical performance. As a result, the assembled batteries deliver good capacity with stable cyclability, and a pouch cell made using this electrolyte displays exceptional endurance in several extreme environments like fire, immersed in water, and immersed in liquid nitrogen.
