Abstract

High surface area hollow carbon hemispheres (HCHs) covered with hard carbon layers have been synthesized by using polystyrene spheres (PSs) as templates under hydrothermal method combined with the intermittent microwave heating (IMH) method. The morphologies of the materials are characterized by SEM and TEM. The electrochemical properties of the HCHs are tested. Comparing with graphite and mesocarbon microbeads (MCMB) ,the HCHs show higher capacity and excellent cyclic life performance.
