Ball-milling assisted solid-state reaction synthesis of mesoporous Li4Ti5O12 for lithium-ion batteries anode

► Mesoporous Li4Ti5O12 is prepared via ball-milling assisted solid-state reaction. ► Li4Ti5O12 consists of ultrafine nanoparticles and well-defined mesopores. ► The as-prepared sample shows good high-rate and cycle performance. ► The route could be practical for the mass synthesis of Li4Ti5O12 anodes.
