Abstract

original image

Interconnected hollow carbon nanospheres (HCNSs) were prepared by pressure-assisted reduction and graphitization of sucrose in autoclaves without template. The obtained HCNSs with a large surface area, very thin graphitic shells, and an interconnected structure exhibit excellent performances as the electrode material for lithium ion batteries.
