Abstract

original image

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.
