Because of the nondirectional property of ionic bond and the fully delocalized property of pi electrons on carbon layers, translation will not change the electronic structure of carbon layers, resulting in that A-GIC and AE-GIC hare quite good lubrication as well. The electrons come from metals mainly transfer to the delocalized pi orbitals of carbon layers, and the increase of delocalized electrons will make metal graphite intercalation compound more electro-conductive than graphite itself. Because ionic bond between metals and carbon layers is weaker and its lattice energy is much less than that of typical NaCl crystal, so metals could be left from interlayers. The Mulliken populations of C-C in intercalation compounds are smaller than that of graphite, and the HOMO energy level of GIC is higher than that of graphite too. These Lead to that GIC will easier be oxidized.
由于离子键没有方向性,又由于碳层中的π电子是充分离域的,所以碳层不会由于平移而改变其电子结构,金属石墨层间化合物仍具有很好的润滑性;金属失去的电子主要转移到碳层的离域π轨道中,碳层离域电子增多使金属石墨层间化合物的导电性比石墨增强;金属与碳层间的离子键强度比较弱,其晶格能远小于典型的离子晶体,因而金属易从石墨层中脱出;金属石墨层间化合物中的C-C间Mulliken布居值小于石墨中C-C间的值,且金属石墨层间化合物的HOMO能级也高于石墨的HOMO能级,所以石墨层间化合物中的碳原子较石墨更易被氧化。
