Materials for electrochemical capacitors
TL;DR: This work has shown that combination of pseudo-capacitive nanomaterials, including oxides, nitrides and polymers, with the latest generation of nanostructured lithium electrodes has brought the energy density of electrochemical capacitors closer to that of batteries.
Journal ArticleDOI
A review of electrode materials for electrochemical supercapacitors
TL;DR: Two important future research directions are indicated and summarized, based on results published in the literature: the development of composite and nanostructured ES materials to overcome the major challenge posed by the low energy density.
Journal ArticleDOI
Graphene-Based Ultracapacitors
TL;DR: CMG materials are made from 1-atom thick sheets of carbon, functionalized as needed, and here their performance in an ultracapacitor cell is demonstrated, illustrating the exciting potential for high performance, electrical energy storage devices based on this new class of carbon material.
Journal ArticleDOI
Pseudocapacitive oxide materials for high-rate electrochemical energy storage
TL;DR: In this article, the pseudocapacitance properties of transition metal oxides have been investigated and a review of the most relevant pseudo-capacitive materials in aqueous and non-aqueous electrolytes is presented.
Journal ArticleDOI
Carbon properties and their role in supercapacitors
TL;DR: Supercapacitors are able to store and deliver energy at relatively high rates (beyond those accessible with batteries) because the mechanism of energy storage is simple charge-separation (as in conventional capacitors) as discussed by the authors.

"Inner" and "outer" active surface of RuO2 electrodes
TL;DR: In this paper, the dependence of the voltammetric surface charge q* on solution pH and potential scan rate has been investigated using a set of RuO2 electrodes prepared by thermal decomposition of RuCl3 at temperatures in the range 300-500°C.

Stochastic Transport in a Disordered Solid. I. Theory
TL;DR: In this paper, a general theory of stochastic transport in disordered systems has been developed, based on a generalization of the Montroll-Weiss continuous-time random walk (CTRW) on a lattice.
