Bulk degradation processes are examined in the LiNiO₂ cathode using high resolution solid-state NMR, combined with magnetometry and X-ray diffraction. Capacity decay is correlated with bulk heterogeneity, whereby multiple structural domains coexist in the charged state, and the Li content and electrochemical activity of these domains is unraveled for the first time.

通过高分辨率顺磁核磁共振光谱对 LiNiO2 阴极老化的新见解

使用高分辨率固态核磁共振并结合磁力测定和 X 射线衍射来检查 LiNiO ₂阴极的整体降解过程。容量衰减与体异质性相关，多个结构域在带电状态下共存，并且这些域的锂含量和电化学活性首次被揭示。
