Researchers have used in situ NMR combined with density-functional theory calculations to resolve the mystery of what happens inside batteries
Using these combined techniques, the researchers were able to develop a ‘map’ of how silicon transforms when it is put into contact with lithium in a battery. The insights opened up by the technology will boost further developments of silicon batteries, as it will be easier for engineers to control their properties.
Dr Andrew Morris, a Winton Advanced Research Fellow, performed the DFT calculations, with the experimental work led by Dr Ken Ogata with collaborators in the departments of Engineering, Chemistry and Material Science and Metallurgy. The results are reported in the 3 February edition of the journal Nature Communications.
