AlCl 3 -graphite intercalation compounds (AlCl -GICs) with a wide interlayer spacing benefit faster Li + diffusion. The low molecular weight and conversion reaction of the pillar further enhance specific capacity per mass.

2014 The tight binding calculation of the orbital magnetic susceptibility in Graphite Intercalation Compounds is reexamined to account for the different behaviour of Donor and Acceptor Compounds. The two dimensional tight binding model for 03C0 electrons treating symmetrically valence and conduction bands cannot explain experimental data. The inclusion of the second neighbour in-plane interacti...

Batteries that shuttle multivalent ions such as Mg and Ca ions are promising candidates for achieving higher energy density than available with current Li-ion technology. Finding electrode materials that reversibly store and release these multivalent cations is considered a major challenge for enabling such multivalent battery technology. In this paper, we use recent advances in high-throughput...

The temperature dependence of the open-circuit potential of lithium half-cells was measured for electrodes of carbon materials having different amounts of structural disorder. The entropy of lithium intercalation, DS , and enthalpy of intercalation, DH , were determined over a broad range of lithium concentrations. For the disordered carbons, DS is small. For graphite, an initially large DS dec...

Ultrasonic exfoliation of expanded graphite compound obtained by cold expansion of graphite intercalated with peroxodisulfuric acid was shown to allow the creation of graphene nanoplatelets with thickness of about 5-10 nm. The resulting graphene material contained surface oxide groups. The expanded graphite intercalation compound was exfoliated by ultrasound much easier than thermally expanded ...
