Graphite is largely divided into natural and artificial graphite. Raw ores of natural graphite are yielded with graphite containing about 5-15% in graphite mines. In order for graphite to be used as an anode material for lithium secondary batteries, it must obtain the purity of at least 99.5% as a battery grade.
