摘要

Carbon-coated mesoporous spinel LiMn₂O₄ has been synthesized from a novel hydrated layered-spinel lithium manganate composite through a facile hydrothermal process and subsequent thermal treatment. Benefiting from the carbon coating and mesoporous structure, the LiMn₂O₄ material exhibits superior high-rate capability and long-life cycling stability, delivering the initial discharge capacity of 117.8 mA h g?1 at 30C with over 90% capacity retention after 1500 cycles. Moreover, the innovative employment of hydrated layered Li-deficient and spinel Li-rich intermediates might provide greater inspiration for other high-performance electrode materials with multiple layer architectures and optimized phase compositions.
