Abstract

Abstract : A C@LiFePO4 /carbon nanotubes microsphere composite (C@LFP/CNTs) with a unique double carbon (amorphous carbon and graphitized conductive carbon) modified hierarchical porous structure for providing favorable kinetics for both electron and Li + is reported. By combining large tap density and improved mixed (electronic and ionic) conductivity, high volumetric energy density and superior rate capacity as well as excellent cycling stability are simultaneously achieved.
