Abstract

Abstract : In article1605650, Yan Yu and co‐workers introduce a "double‐carbon‐shell" concept in lithium‐ion batteries, by which dual functions are performed: confining the volume change of silicon and stabilizing the solid electrolyte interface (SEI). Multi‐point contacts substantially increase the electronic conductivity and decrease the Li + diffusion length to the nanoscale. Such a concept can be applied to synthesize materials with large volume changes in cycles by simultaneously enhancing the electronic conductivity and controlling the SEI growth of lithium‐/sodium‐ion batteries.
