摘要:
The diffusion coefficient of lithium in graphite is an important parameter for the use of graphite because it relates to the ability of charge and discharge rate of lithium battery. It remains a problem that there are often obvious differences among the diffusion coefficients obtained using different methods, even in one paper[1,2]. This difference may attribute to the complicate properties of intercalation process, as well as some uncertain parameters of the porous structure electrode. In order to measure the diffusion coefficient of lithium in carbon more precisely, a well crystallized material Highly Oriented Pyrolytic Graphite (HOPG) was used as the material of working electrode in this study.
