In this research, a carbonized chicken feather for anode materials was prepared using the pyrolysis method. While the activation process of carbon utilized KOH variations (1M, 3M, and 5M) which was pyrolyzed at 700 oC. In addition, the surface area, crystalline structures, and morphologies of the activated carbonized chicken feather (CFCAs) were investigated by the X-ray diffraction, BET, FTIR, and SEM. Furthermore, their various electrochemical properties in LIBs were also examined, with the chemical activation process decreasing the crystallite size. The activated carbon has a small reduction and oxidation peaks, which attributed to the insertion of Li-ion into the voids in carbon. The results show that activated carbon with KOH 5 M has the highest discharge rate capacity at 445.87 (mAhg-1).
