TL;DR: Using synchrotron X-ray microdiffraction, state-of-charge profiles in-plane and normal to the current collector were measured as mentioned in this paper, showing that the portion of a prismatic cell electrode closest to the collector tab had the highest state of charge due to electronic resistance in the composite electrode and supporting foil.

TL;DR: Micron sized, three dimensional (3D) nanoporous spherical LiFePO4/C synthesized by spray pyrolysis shows excellent cyclability and superior rate capability.

TL;DR: In this paper, spherical nanoporous LiCoPO4/C composite microparticles were synthesized from soluble precursors by spray pyrolysis and achieved a reversible capacity of 123 mAh g−1 at C/10 rate, and showed excellent cycling behavior and rate capability.

TL;DR: In this article, soft x-ray absorption spectroscopy of NMC532 electrodes, both pristine and those charged to 4.2, 4.35, or 4.5 V, was performed.

TL;DR: The combined experimental and theoretical studies show that the non-rigid electron state reshuffling guarantees the stability of oxygen during the redox reaction throughout the charge and discharge process of LiFePO4 electrodes, leading to the intrinsic safe performance of the electrodes.
