The cover image focuses on a new class of solid electrolytes termed frameworked electrolytes, where the “macroscopically solid” frameworks are purposely laden with 3D ionic channels in the sub-nano scales, giving rise to both a high ionic conductivity and a desirable interface with the electrode solids. The authors demonstrate a zeolite framework structure based frameworked electrolyte with superior ion diffusion kinetics, which ensures the design of high-performance all solid state battery running at room temperature. It is confident that the emergence of frameworked electrolyte serves as a powerful motivator for embarking on a new expedition to design the next-generation battery for EVs or portable electronics in the future.
