SLShiqi LiuBeijing University of TechnologyBWBoya WangYanshan UniversitySTShaoze TianNorth China Electric Power University

Key Points

  • The research aims to improve lithium-ion diffusion in manganese-based composite cathodes for better battery efficiency.
  • Engineering composite structures with dual defects to optimize Li+ movement.
  • Testing the electrochemical performance of the modified cathodes.
  • Analyzing the stability and lifespan under practical battery conditions.
  • Engineered cathodes show significantly improved Li+ diffusion rates.
  • Reduced voltage fade and enhanced structural stability were observed.
  • The modified materials demonstrated better longevity compared to conventional cathodes.

Abstract

Manganese-rich layered oxides are promising cathodes for next-generation lithium-ion batteries, yet their practical deployment is hindered by sluggish Li+ diffusion, voltage fade, and Mn dissolution triggered by lattice instability. To...
