Charge‐Discharge Mechanism of Graphitized Mesocarbon Microbeads

Abstract

The charge‐discharge reaction mechanism of the graphitized mesocarbon microbead (MCMB) anode was investigated with cyclic voltammetry and x‐ray diffractometry. It is concluded that the charge‐discharge reaction of graphitized MCMB involves intercalation of lithium, which is essentially similar to that for graphite. However, the in‐plane ordering of the stage 1 and 2 Li‐GICs obtained from the graphitized MCMB is not like graphite, but is close to , according to the results of both x‐ray diffractometry and cyclic voltammetry.
