石墨被广泛用作几乎所有锂离子电池的负极材料。Li很容易被吸附到石墨的层状结构中，在LiC6和C之间形成锂碳插层化合物LixC。然而，虽然它们是简单的二元化合物，但它们的结构长期以来一直没有被阐明，特别是LiC12和C之间的化合物。这可能是因为Li的浓度太低，不能使这些Li插层石墨与纯石墨的衍射图有很大的差别。然而，众所周知，它们具有堆积的层结构，这强烈地表明它们很可能形成调制结构。基于调制结构模型成功地进行了这些化合物的结构分析，全面阐明了LiC6和C之间的所有LixC结构。
Graphite is widely used as an anode material in almost all Lithium (Li)-ion batteries. Li is easily absorbed into the layer structure of graphite, forming lithium-carbon intercalation compounds LixC between LiC6and C. However, although they are simple binary compounds, their structures have been left unelucidated for a long time, especially for the compounds between LiC12and C. This is probably because the Li concentrations are too low to make a big difference in diffraction pattern between these Li-intercalated graphites and pure graphite. It has been known, however, that they have stacked layer structures, which strongly suggests that they are very likely to form modulated structures. Structural analyses of these compounds based on the modulated structure model were successfully performed, comprehensively elucidating all the LixC structures lying between LiC6and C.
