Abstract: Carbonaceous materials are derived by the pyrolysis of sorona at 900°C. The structure and morphology of the materials are analyzed. Scanning electron microscopy (SEM) reveals the porogen free carbon show flake-like disordered materials. Thermal gravimetric analysis (TGA) and differential temperature analysis (DTA) of samples show the weight loss at around 100°C and 400°C attributed to loss of superficial moisture and destructive distillation of sorona. X-ray diffraction (XRD) studies of the pyrolytic carbon indicate the presence of small domains of coherent and parallel stacking of the graphene sheets. N2 adsorption analysis reveals an average Brunauer, Emmett and Teller (BET) surface area 3.59 m2/g for non-porogen sorona carbon. The prepared porogen sorona carbon is used as the anode materials for Li ion battery and electrochemical behavior is investigated. Charge-discharge test and cycling studies give good capacitive properties. The use of pyrolytic carbon derived from sorona as anode materials for lithium batteries is novel, inexpensive and simple.
