Mesophase pitch-derived synthetic graphite was hybridized with natural graphite/carbon nanofiber (NG/CNF) composites prepared by mechanical mixing, carbonization, and graphitization processes. Addition of the NG/CNF composites introduced effective internal pores inside the synthetic graphite matrix, thereby improving the rate performance, 1st cycle coulombic efficiency, and cyclability. Hybridized graphite with 10 wt% of added NG/CNF composite exhibited the best rate performance, with a discharge capacity retention rate of over 90% after a 5 C discharge test.
