Key Points

The ordered-phase LNMO cathode achieves a capacity of 75.4% after 200 cycles at 1C, indicating significant stability.
An energy density of 451.67 Wh kg−1 was recorded, showcasing the effectiveness of the spinel-type design in high-voltage applications.
Synthesis focuses on phase-purity-engineering strategies to suppress Mn dissolution and maintain a stable 4.0 V plateau.
The findings suggest potential implications for the development of stable high-voltage batteries in energy storage.

Implication

This research develops a novel cathode with improved energy density and capacity, indicating enhanced electrochemical stability.
