Abstract

A process for purifying and producing coated high purity particulate graphite materials suitable for use in lithium-ion batteries (LiBs) is described herein. More specifically, the process comprises agglomerating a graphite feed or treating a graphite feed with an agglomerating agent to produce an agglomerated particulate graphite feed; and reacting the agglomerated particulate graphite feed in the presence of a chlorine-containing gas to produce a mixture comprising a purified agglomerated particulate graphite material and a chlorine-containing gas laden with chlorinated impurities. The process may further comprise an alkaline leaching step. A coated particulate graphite material comprising a purity in excess of 99.95 wt. % C. and its use as anode material in rechargeable LiBs is also disclosed.
