Synthesis of activated carbon derived from chicken feather for Li-ion batteries through chemical and physical activation process

Abstract The use of activated carbon from biomass as an electrode for lithium-ion batteries is promising because the low cost, natural abundance, and environmentally friendly. Chicken feather a that has potential to be source carbon, it contains keratin. activation process affects quality thereby increasing battery performance. In this study, chicken waste was chemically using KOH combined with physical at temperature variations 750, 850 950 °C. significantly influenced electrochemical properties difference in their microstructure. pyrolyzed °C (CFCA-850) shows highest discharge capacity 285.78 mAhg −1 , good cycling stability rate performance due its higher interlayer spacing large surface area. Furthermore, electronic conductivity ion increase, thus improve
