High‐capacity anode materials are important for Li‐ion batteries for automobile applications. On page 95 , Y. Cao, J. Liu and coworkers use simple and scalable high‐speed milling to produce a nanocomposite made of SiC coated with few‐layer graphene, with tin oxide nanoparticles trapped between the two. This material exhibits an exceptional high‐reversible capacity for Li‐ion storage, almost two times higher than the theoretical capacity of the alloying reaction normally observed in common tin oxide anode materials.
