Abstract :
Many investigations have focused on application of natural graphite as the anode material in Lithiumion rechargeable batteries (LIB). Vein graphite is the highly crystalline and chemically purest form of natural graphite, other two are flake and amorphous. Already, flake graphite has been introduced to the anode application in LIB, however, through very costly and hazardous processes. Comparable to flake graphite, vein graphite possess a great potential with its excellent characteristics. Presently, Sri Lanka is the only commercial supplier of vein graphite in the world. However, in order to make them feasible for LIB application, our vein graphite have to be subjected to a thorough value addition. Therefore this study focused on the value addition to Sri Lankan vein graphite through purification and necessary surface modification, for the anode application of LIB. For that, raw graphite samples
