We review oxygen K-edge X-ray absorption spectra of both molecules and solids. We start
with an overview of the main experimental aspects of oxygen K-edge X-ray absorption …

Safety is essential to battery sustainability, particularly considering that flammable organic
molecules still dominate the electrolyte formulation. For a single electrolyte chemistry …

Hard carbons have shown considerable promise as anodes for emerging sodium-ion battery
technologies. Current understanding of sodium-storage behaviour in hard carbons attributes …

Abstract Electrochemical Performance of aqueous Zn‐ion batteries (AZIBs) is prominently
constrained by poor stability of zinc‐metal anodes. However, the use of conventional …

Cryogenic transmission electron microscopy (cryo-TEM) is a valuable tool recently proposed
to investigate battery electrodes. Despite being employed for Li-based battery materials …

Two-dimensional (2D) metal–organic framework (MOF) nanosheets have been recently
regarded as the model electrocatalysts due to their porous structure, fast mass and ion …

Carbon nanofibers films are typical flexible electrode in the field of energy storage, but their
application in Zinc-ion hybrid capacitors (ZIHCs) is limited by the low energy density due to …

Inspired by dative boron‐nitrogen (B← N) bonds proven to be the promising dynamic
linkage for the construction of crystalline covalent organic polymers/frameworks …

Rechargeable magnesium and calcium metal batteries (RMBs and RCBs) are promising
alternatives to lithium-ion batteries because of the high crustal abundance and capacity of …

O3-type layered oxide materials are considered to be a highly suitable cathode for sodium-
ion batteries (NIBs) due to their appreciable specific capacity and energy density. However …
