dc.description.abstractHigh quality vein graphite, containing 95-99% of pure carbon in Sri Lanka has been identified as promising candidate as anode material in lithium ion rechargeable battery. Purification and mild oxidation have been widely used to enhance the property of the vein graphite as anode material (Balasooriya et al., 2007; Amaraweera et al., 2013). However, alkali carbonates coating which are identified as cost effective and nontoxic approach for the surface modification have not been investigated for vein graphite in Sri Lanka (Komaba et al., 2008; Zhang et al., 2003). Therefore, present work is aimed to develop low cost anode material based on Li2CO3 coating of purified vein graphite. Methodology Purified vein graphite powder less than 53µm (<53 µm) was used for this study (Amaraweera et al., 2013). Graphite powder were added into an agate motor and milled for about 2 hours by adding aqueous Li2CO3to ensurethat the graphite was completely witted. Then the surrey was dried in vacuum at 100 C. The modification of the graphite mixture was characterized by FTIR Spectroscopy D.C conductivity of graphite powder and sheet conductivity of graphite electrode was measured by four-probe and VanderPauw, methods respectively.en_US
