Angewandte Chemie International Edition, Volume 65, Issue 9, 23 February 2026.In situ high‐temperature X‐ray diffraction (XRD) and absorption spectroscopy (XAS) reveal state dependent thermal evolution of Li1.2Ni0.2Mn0.6O2. Pristine electrodes transform from layered‐to‐spinel, while cycled electrodes convert directly to Li‐containing rock‐salt. The onset temperature drops with delithiation and partly recovers after relithiation.

Battery Energy, Volume 5, Issue 1, January 2026.Niobium (Nb) incorporation into spinel LiMn2O4 achieves simultaneous enhancement of ionic diffusion kinetics and particle size. After Nb doping, the overall surface energy decreases, promoting particle growth. Despite the increased particle size, the introduction of niobium significantly improves the rate capability and effectively mitigates ...
