Staging Transitions In Li-Graphite: Phonon Spectra of Dilute Stage 1

MRS Online Proceedings Library volume 20, Article number: 265 (1982) Cite this article

Abstract

First-order transitions to dilute stage one from stages 2,3 and 4 and from mixed stage 1+2 are observed in Li-graphite as predicted by Safran. The upper phase boundary is asymmetric in concentration and is sharply peaked about x ∼ 0.4. The phonons in the dilute stage 1 have energies between those of LiC6 and graphite. Unlike the stage 2 compounds, the compressibility does not scale in a simple way with intercalant density.

    We also studied several other donor and acceptor intercalated graphite compounds ranging from stage two to stage seven in x-ray diffraction and failed to observe staging transitions at temperatures below which the compound decomposes or deintercalates.
