Synthesis of Ordered Mesoporous Li–Mn–O Spinel as a Positive Electrode for Rechargeable Lithium Batteries

Abstract

Sturdy spinel: A mesoporous Li–Mn–O spinel (Li1.12Mn1.88O4) with superior rate capability at ambient temperature is synthesized. Comparable stability to the bulk material at elevated temperatures is also observed, despite a surface area of 90 m2 g−1 for the mesopore, suggesting that the internal mesopore surfaces are more stable than the external surface.
