Plasma-enhanced low-temperature solid-state synthesis of spinel LiMn ₂ O ₄ with superior performance for lithium-ion batteries

In this work, for the first time, we develop a plasma-enhanced low-temperature solid-state strategy to prepare LiMn ₂ O ₄ with low energy consumption and superior performance for Li-ion batteries. The as-prepared LiMn ₂ O ₄ shows a narrow particle size distribution in the range of 400–450 nm and smaller mean particle size.
