Abstract
The research of the development kerosene soot carbon particles and its application as electrode for lithium ion battery has been done. The carbon was prepared from kerosene by using thermal plasma pyrolisis and characterized by Boehm titration in order to determine the carbon functional group, point zero charge for surface charge and X-ray diffraction for crystalography. Carbon was mixed with polianilin to form anode and mixed with lithium, iron salts and phosphate to form LiFePO4 as cathode. Both electrodes were fabricated into lithium ion battery with Li2SO4 as electrolyte. The performance of battery was measured with the variaton of electrolyte concentration i e., 0.1 M, 0.5 M, and 1 M. Boehm titration result showed that the carbon has acid functional groups greater than base functional group as 6.90 mgeq. 4.80 of point zero charge pH was in acid condition. The crystalography of carbon as anode presented in diffractogram showed 2θ = 23.68 and 42.33 of diffraction peaks and indicated graphite crystal in the carbon. CV measurement reveal that the oxidation occurred at the peak of anode current, i.e.,0.015 A for 0.3 V whereas the reduction occured at the -0.3 V and 0.007 A. A Galvanostatic charge discharge measurenment showed that The highest capacity is obtained in 0.52 mAh/g with a voltage of 0.71 Volts, which is the 500 th cycle. The lowest capacity is obtained in only 0.15 mAh/g of 0.2 Volts, that is in cycle 1st.
