Abstract Hard carbon (HC) is the most promising anode for commercialization of sodium‐ion batteries (NIBs); however, a general mechanism sodium storage in HC remains unclear, obstructing development highly efficient anodes NIBs. To elucidate pores, operando synchrotron small‐angle X‐ray scattering, wide‐angle absorption near edge structure, Raman spectroscopy, and galvanostatic measurements are combined. The multimodal approach provides mechanistic insights into pore‐filling process...
Aqueous zinc-ion batteries (ZIBs) employing zinc metal anodes are gaining traction as for moderate to long duration energy storage at scale. However, corrosion of the anode through reaction with water limits battery efficiency. Much research in past few years has focused on additives that decrease hydrogen evolution, but precise mechanisms by which this takes place often understudied and remain unclear. In work, we study role an acetonitrile antisolvent additive improving performance aqueous...
Hard carbon (HC) is a leading anode material for sodium-ion batteries, but its complex microstructure complicates understanding of sodium storage mechanisms. Using X-ray total scattering and density functional theory calculations, this study clarifies how HC’s microstructural variations influence across the slope (high potential) plateau (low regions potential-capacity curve. In region, initially adsorbs at high-binding energy defect sites subsequently intercalates between graphene layers,...
Aminopolycarboxylate chelates are emerging as a promising class of electrolyte materials for aqueous redox flow batteries, offering tunable potentials, solubility, and pH stability through careful selection ligands transition metal ions. Despite their potential, the impact molecular structure modifications on electronic electrochemical properties these remains underexplored. Here, we examine how introducing hydroxyl group, often employed its solubilizing properties, to backbone CrPDTA,...
