All‐in‐One Interface Engineering From Bulk to Electrode Toward High‐Performance Micro‐Sized Silicon Anodes

open access: yesSmall, EarlyView.
Microsized silicon (µ‐Si, >1 µm) is one of the ideal anodes for lithium‐ion batteries. In this paper, an integrated co‐carbonization electrode (ICCE) without binder and conductive agent was prepared by precoating a uniform carbon layer on the surface of µ‐Si particles, which significantly improved the electrochemical performance.
