Porous yet densely packed carbon electrodes with high ion-accessible surface area and low ion transport resistance are crucial to the realization of high-density electrochemical capacitive energy storage but have proved be very challenging produce. Taking advantage chemically converted graphene's intrinsic microcorrugated two-dimensional configuration self-assembly behavior, we show that such materials can readily formed by capillary compression adaptive graphene gel films in presence a...
A simple, bioinspired approach to effectively prevent the restacking of chemically converted graphene sheets in multilayered films is presented. The method enables creation a new generation supercapacitors that combine high energy density, power and operation rates. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
The intrinsic catalytic activity at 10 mA cm-2 for oxygen evolution reaction (OER) is currently working out overpotentials higher than 320 mV. A highly efficient electrocatalyst should possess both active sites and high conductivity; however, the loading of powder catalysts on electrodes may often suffer from large resistance between current collectors. This work reports a class bulk amorphous NiFeP materials with metallic bonds viewpoint electrode design. reported here perfectly combine...

However, effect surface structure on inherent nucleation and deposition Zn not yet well understood. Here, a anode reconstructed Sn‐crystal textures via facile chemical displacement reaction. Compared bare Zn, high‐affinity binding sites Sn afford lower energy barrier, which promotes kinetics. What more, Sn‐textured moderate affinity but high average...
Abstract High‐performance, breathable, conductive, and flexible polypyrrole (PPy) coated paper electrodes are prepared by an interfacial polymerization method using air‐laid as a substrate. Owing to the synergistic effect of superior electrical conductivity, high wettability, porous architecture, electrode not only shows outstanding specific capacitance rate abilities (3100 2579 mF cm −2 at 1 20 mA for PPy electrode), but also exhibits excellent flexibility, wearability, breathability.

Metallic magnesium batteries are promising candidates beyond lithium-ion batteries; however, a passive interfacial layer because of the electro-reduction solvents on Mg surfaces usually leads to ultrahigh overpotential for reversible chemistry. Inspired by excellent separation effect permselective metal-organic framework (MOF) at angstrom scale, large-area and defect-free MOF membrane directly is here constructed. In this process, electrochemical deprotonation ligand can be facilitated...

Rechargeable magnesium (Mg) batteries based on conventional electrolytes are seriously plagued by the formation of ion-blocking passivation layer Mg metal anode. By tracking Mg2+ solvation sheath, this work links components to -solvents (1,2-dimethoxyethane, DME) coordination and consequent thermodynamically unstable DME molecules. On basis, we propose a methodology tailor introducing additive solvent with extreme electron richness. Oxygen atoms in phosphorus-oxygen groups compete that...
Mg anodes are hindered by a huge overpotential and limited cycling life, stemming primarily from the unstable interphase between electrolyte. An effective approach lies in establishing an anion-derived, inorganic-rich solid–electrolyte (SEI) that mitigates continuous reduction of Nevertheless, high charge density divalent cations poses significant challenge balancing coordination dissociation anions within Mg2+ solvation sheath. Herein, selecting small-sized OTf–, diglyme solvent, trimethyl...
