Abstract

Abstract : A unique high full‐electrode basis capacity anode design for secondary batteries is described by P. V. Braun and co‐workers on page 6265. The design consists of a structurally robust 3D Fe3 O4 /C composite, which provides efficient pathways for electron and Li‐ion transport, and space for the volume changes during cycling. On a full‐electrode basis, the template‐free nanocomposite anode exhibits attractive electrochemical performance, including a high volumetric capacity which significantly exceeds both the practical and theoretical capacity of a commercial graphite‐based anode.
