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. N<sub>2</sub> adsorption analysis reveals an average Brunauer, Emmett and Teller (BET) surface area 3.59 m<sup>2</sup>/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.
