摘要
本文利用间歇电量滴定法(GITT)研究了锂在苯碳黑和树脂裂解碳等碳素材料中嵌入时的扩散过程,结果表明,锂在不同碳素材料的石墨微晶区中的扩散过程基本相似,扩散系数在10^(-9)cm^2/s数量级,而在碳素材料的非石墨化区中的扩散则与碳素材料的结构有很大关系.
The galvanostatic intermittent titration technique(GITT) was employed to investigate the diffusion processes of lithium in carbon materials. The results showed that the diffusion coefficients of lithium in the graphite region of carbon materials are all similar,while in the non-graphitic region they vary with the structure of the carbon materials.
