Key Points

The research aims to enhance the durability of LiCoO2 cathodes during fast charging by modifying lattice structures.
Modifying the lattice oxygen and surface structure of LiCoO2 to improve stability during fast charging.
Assessing structural integrity, lattice strain, and microcrack formation during high-voltage operation.
Reduced lattice strain and enhanced structural stability during fast charging.
Minimized gas release and microcrack formation at elevated voltages.

Abstract

. Our strategy suppresses lattice strain, structural degradation, and microcracks, and alleviates gas release during fast charging at high voltage, revealing the potential of lattice engineering to meet the demands of high-voltage batteries.
