Schematic of the Experiment (IMAGE) Diamond Light Source Caption New paper in Nature Energy, reveals how researchers fully identified the nature of oxidised oxygen in the important battery material - Li-rich NMC - using RIXS (Resonant Inelastic X-ray Scattering) at Diamond Light Source. This compound is being closely considered for implementation in next generation Li-ion batteries because it delivers higher energy density than current materials, and could translate to longer driving ranges for electric vehicles and enable scientists to tackle issues like battery longevity and voltage fade Credit Diamond Light Source & University of Oxford Usage Restrictions None License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
