Abstract

A magnifying glass symbolizes the structural insights gained through X-ray diffraction and operando X-ray absorption spectroscopy, enabling detailed understanding of the structural evolution and redox mechanisms of the multicomponent spinel during cycling. These complementary techniques reveal how the multidoping approach suppresses Jahn-Teller distortion, preserves structural integrity, and enhances the reversibility of the Mn(III)/Mn(IV) and Mn(II)/Mn(III) redox couples, leading to improved structural stability.

封面：LiCrxFeyMn2−x−y−zTizO4尖晶石作为锂离子电池的阴极：一种抑制扬-泰勒扭曲的多掺杂方法（ChemElectroChem 7/2026）

放大镜象征着通过x射线衍射和operando x射线吸收光谱获得的结构见解，可以详细了解多组分尖晶石在循环过程中的结构演变和氧化还原机制。这些互补技术揭示了多掺杂方法如何抑制Jahn-Teller畸变，保持结构完整性，并增强Mn(III)/Mn（IV）和Mn(II)/Mn（III）氧化还原对的可逆性，从而提高结构稳定性。
