To unlock the potential of Mn-based cathode materials, the fast capacity fading process has to be first understood. Here the authors utilize advanced characterization techniques to look at a spinel LiMn2O4 system, revealing that a combination of irreversible structural transformations and Mn dissolution takes responsibility.
