| dc.description.abstract | Modification of natural graphite has recently moved into the focus of the preparation of anode materials for lithium ion batteries. It has been reported that, modification of natural graphite by coating Li2CO3 formed stable SEI at elevated temperature. The Li2CO3 coated graphite shows lower self-delithiation in storage and better capacity retention in long-term cycling. Recent studies on Sri Lankan natural vein graphite indicate that it has sufficient electrical conductivity to use as potential candidate for Lithium ion rechargeable batteries [7]. Li2CO3coating increases the capacity of natural vein graphite. The study aims to Li2CO3coating of natural vein graphite to improve its surface structure. Different structural varieties of natural vein graphite powder were coated with Li2CO3 to improve its surface structure. This coating Li2CO3 is uniformly distributed throughout the graphite surface. According to the FTIR data, absorption peaks corresponding to the Li2CO3 cleanly appear after the coating. Moreover, Li2CO3 precipitate of active sites such as the catalytic site and edge plane. Consequently, the electrical conductivity of the graphite was in same range after the modification. Key Words: Surface Modification, Li2CO3 coating, Solid Electrolyte Interphase | en_US |
