Solids that simultaneously conduct electrons and ions are key elements for the mass transfer and storage required in battery electrodes. Single-phase materials with a high electronic and high ionic conductivity at room temperature are hard to come by, and therefore multiphase systems with separate ion and electron channels have been put forward instead. Here we report on bilayer graphene as a single-phase mixed conductor that demonstrates Li diffusion faster than in graphite and even surpassing…

Adsorption and ultrafast diffusion of lithium in bilayer graphene: Ab initio and kinetic Monte Carlo simulation study

In this work, we adopt first-principle calculations based on density functional theory and Kinetic Monte Carlo simulations to investigate the adsorption and diffusion of lithium in bilayer graphene

Lithium intercalation into bilayer graphene

It is clarified that lithium atoms can be stored only in the graphene interlayer and the first ever planar lithium-intercalation model for graphenic carbons is proposed, which will guide the development of graphene materials in lithium ion batteries.

Kinetic Ionic Permeation and Interfacial Doping of Supported Graphene

Terahertz spectroscopy is employed as a contact-free means to investigate the impact of ubiquitous cations in aqueous solution on the electronic properties of SiO2-supported graphene and shows that the ion-induced Fermi level shift of graphene involves cationic permeation through graphene.

Reversible superdense ordering of lithium between two graphene sheets

Using a double-aberration-corrected transmission electron microscope, intercalation of lithium between two graphene sheets is found to produce a dense, multilayer lithium phase, rather than the expected single layer.

Ultrafast Lithium Diffusion in Bilayer Buckled Graphene: A Comparative Study of Li and Na

The effect of the curvature of bilayer graphene on the interlayer diffusion of Li atoms is investigated using molecular dynamics simulations. A spectacular enhancement of the diffusion constant

Atomic-scale ion transistor with ultrahigh diffusivity

In situ optical measurements suggest that ultrafast ion transport likely originates from highly dense packing of ions and their concerted movement inside the graphene channels, and shows a threshold behavior due to the critical energy barrier for hydrated ion insertion.



Synergistic, ultrafast mass storage and removal in artificial mixed conductors

It is shown, using electrochemical and chemical methods, that a melt-processed composite of the ‘super-ionic’ conductor RbAg4I5 and the electronic conductor graphite exhibits both a remarkable silver excess and a silver deficiency, similar to those found in single-phase mixed conductors, even though such behaviour is not possible in the individual phases.

A high-mobility electronic system at an electrolyte-gated oxide surface

This work demonstrates that limitations of electrolyte gating can be overcome by protecting the sample with a chemically inert, atomically smooth sheet of hexagonal boron nitride, which should enable future studies where high carrier density modulation is required but electrochemical reactions and surface disorder must be minimized.

Suppression of Metal-Insulator Transition in VO2 by Electric Field–Induced Oxygen Vacancy Formation

It is found that electrolyte gating of epitaxial thin films of VO2 suppresses the metal-to-insulator transition and stabilizes the metallic phase to temperatures below 5 kelvin, even after the ionic liquid is completely removed.
