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.
