Dopant-controlled transition-metal ordering in high-voltage spinel cathodes

LZLi ZhangBMBeth E. MurdockXHXiao Hua

Key Points

  • To explore how Fe doping affects cation ordering and redox behavior in LiMn 1.5 Ni 0.5 O 4 spinel cathodes.
  • Conducted neutron PDF analysis
  • Examined site-selective cation redistribution
  • Analyzed redox behavior and performance metrics
  • Fe doping alters cation distribution across various scales
  • Tuning cation sites directly impacts redox behavior
  • Enhanced battery performance linked to controlled Fe doping

Abstract

Neutron PDF analysis reveals that Fe doping in high-voltage spinel LiMn 1.5 Ni 0.5 O 4 drives site-selective cation redistribution across length scales, directly tuning redox behaviour and battery performance.
