Abstract

Two potential pathways for Li+ diffusion occur within graphitic carbon with typically in-plane diffusion dominating (similar to 10(-7) cm(2) s(-1)) over diffusion along the crystallite grain boundaries (similar to 10(-11) cm(2) s(-1)). Reducing the flake thickness of microcrystalline graphite powders via electrochemical exfoliation offers a method to overcome the latter, sluggish grain boundary Li+ diffusion, thereby increasing the overall rate capability of the graphite negative electrode in a the Li-ion battery. Six micron particulate graphite was electrochemically exfoliated to give flakes of which similar to 90% had a thickness of
