Carbon nanofibers (CNFs) were incorporated into LiFePO4 composite cathode through conventional slurry formulation. Pristine LiFePO4 and modified LiFePO4 cathode samples were characterized by scanning electron microscopy, galvanostatic charge/discharge measurements, and cyclic voltammetry. Electrochemical measurements at room temperature showed LiFePO4/CNF composite to exhibit a higher specific discharge capacity of (similar to)150 mAh g(-1) at 0.1C, excellent high rate performance at >5C capability rates, and better cycling stability with 98.4% capacity retention at 5C after 200 cycles. The improved high C-rate performance of the LiFePO4/CNF composite cathode can be attributed to long-range conducive networks formed through bridges created by the CNFs. The enhanced battery performance indicates promise for high-power applications.
