Abstract
Abstract Hard carbon nanofiber (HCNF) bundles were prepared using reverse hexagonal micelle (H2) phase formed by a template of an amphiphilic block copolymer surfactant and their anode performance in lithium ion batteries was analyzed. Prepared HCNF showed a higher discharge capacity at voltage region above 0.8 V (vs. Li/Li+) than that of control carbon. Rate capability was also examined in order to demonstrate merit of the fibrous morphology of CNF, with current values corresponding to 0.1, 0.2, 0.5, 1 and 2 C rate. Prepared HCNF electrode exhibited higher rate capability than control carbon, which was attributed to morphological difference.
