Operando powder X-ray diffraction (PXRD) is a widely employed method for the investigation of structural evolution and phase transitions in electrodes for rechargeable batteries. Due to the advantages of high brilliance and high X-ray energies, the e

Lithium vanadium fluorophosphate, LiVPO4F, is a promising cathode material for Li-ion batteries because of its high intercalation potential (4.24 V vs Li/Li+) and high stability. However, recent studies show that as-synthesized LiVPO4F very often con

In the present study, three mass-produced commercial IrOx samples from different suppliers were studied to establish correlations between various properties and their OER activities. The structures of the electrocatalysts at different scales were exp

Iron(iii) hydroxide phosphate hydrate Fe1.13(PO4)(OH)0.39(H2O)0.61 is investigated for the first time as a Na-ion battery cathode, which reveals that the material exhibits similar storage capacities for Na-and Li-ions at relatively low current rates
