Carbon materials of various morphologies were synthesized by pyrolysis of Soap-nut seeds (Sapindus mukorossi), JackFruit seeds (Artocarpus heterophyllus), Date-seeds (Phoenix dactylifera), Neem seeds (Azadirachta indica), Tea leaves(Ehretia microphylla), Bamboo stem (Bambusa bambus) and Coconut fiber (Cocos nucifera), without using any catalyst.Carbon materials thus formed were characterized by SEM XRD and Raman. Carbon thus synthesized varied in size (in .m)but all showed highly porous morphology. These carbon materials were utilized as the anode in Lithium secondary battery.Amongst the various precursors, carbon fibers obtained from Soap-nut seeds (Sapindus mukorossi) and Bamboo stem(Bambusa bambus), even after 100th cycles, showed the highest capacity of 130.29 mAh/g and 92.74 mAh/g respectively.Morphology, surface areas and porosity of carbon materials obtained from these precursors were analyzed to providenmaterials assist in the intercalation of lithium. Size of cavity (or pore size of channels type structure) present in carbonmaterials were found to facilitate the intercalation of lithium.
