Computational predictions of energy materials using density functional theory [PDF]
, 2016 In the search for new functional materials, quantum mechanics is an exciting starting point. The fundamental laws that govern the behaviour of electrons have the possibility, at the other end of the scale, to predict the performance of a material for a ...

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes
Advanced Materials, EarlyView.Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

Advanced Materials, EarlyView.The novel gradient‐modified LRMO has been synthesized via a one‐step mechano‐fusion process, with simultaneous S and Zr co‐doping in the near‐surface region and an amorphous coating. The synergistic co‐functionalization stabilizes the oxygen framework, enhances charge transport, and suppresses oxygen dimerization under high potential, which enable ...
