The Synthesis Effects on the Performance of P2‐Na0.6Li0.27Mn0.73O2 Cathode Material for Sodium‐Ion Batteries

open access: yesBattery Energy, Volume 4, Issue 2, March 2025.
The effect of reagents on the structure and performance of sodium‐layered oxides has not yet been thoroughly studied. This work explored this factor systematically through in situ high‐temperature XRD. The samples synthesized via MnCO3‐based precursors form the Li2MnO3 phase at evaluated temperature and perform better than those through MnO2‐based ...
