In this combined theory and experimental work published in Energy and Environmental science we show the dual behaviour of alumina coatings in protecting high-capacity Ni rich NMC cathodes for Li-ion batteries. A plethora of experimental techniques like solid state NMR, XAS, OEMS combined with DFT+U calculations show the chemical effect...
The Faraday Discussion 255: NMR Crystallography is now available online. We thank all the participants who made this discussion a fruitful one.
In this combined theory and experimental chem mater publication we show the efficacy of different DFT functionals based on their localisation in capturing the characteristics of O K edge XAS obtained experimentally for Li-ion battery cathodes. Our work focussing on the pre-edge and edge features show that hybridization, structural distortions,...
