Synthesis of ternary and quaternary graphite intercalation compounds containing alkali metal cations and diamines.
A series of ternary graphite intercalation compounds (GICs) of alkali metal cations (M = Li, Na, K) and diamines [EN (ethylenediamine), 12DAP (1,2-diaminopropane), and DMEDA (N,N-dimethylethylenediamine)] are reported. These include stage 1 and 2 M-EN-GIC (M = Li, d(i) = 0.68-0.84 nm; M = Na, d(i) = 0.68 nm), stage 2 Li-12DAP-GIC (d(i) = 0.83 nm), and stage 1 and 2 Li-DMEDA-GIC (d(i) = 0.91 nm)...

متن کاملStage-l Alkali Metal Graphite Intercalation Compounds: A First Principles Study
Using ab initio Density Functional Theory, we determine changes of the equilibrium structure of graphite due to charge transfer between the alkali intercalant atoms and the host layers. From our self-consistent calculations, we show for stage-l Li and K graphite intercalation compounds that there is a deviation from a universal relationship between charge transfer and the C-C bond length. We fi...
متن کاملNanotribological Properties of Graphite Intercalation Compounds: AFM Studies
Tetraalkylammonium salts have larger ions than metal ions, which can greatly change the interlayer space and energy, and then potentially tune the properties of graphite. In this work, various graphite intercalation compounds (GICs) have been synthesized by intercalating tetraoctylammonium bromide (TOAB) ions into graphite through electrochemical interactions under different reduction potential...
متن کاملVan der Waals density functional study of the energetics of alkali metal intercalation in graphite
We report on the energetics of intercalation of lithium, sodium and potassium in graphite by density functional theory using recently developed van der Waals (vdW) density functionals. First stage intercalation compounds are well described by conventional functionals like GGA, but van der Waals functionals are crucial for higher stage intercalation compounds and graphite, where van der Waals in...
