Preparation of Li4Ti5O12 Nanorods as Anode Materials for Lithium-Ion Batteries

摘要: Li 4 Ti 5 O 12 nanorods are fabricated after calcination of the hydrated lithium titanate precursor, which is prepared from hydrothermal treatment in aqueous LiOH based on nanorod reactivity. The morphology, composition, and phase transformation calcined samples at different temperatures were characterized by X-ray diffraction, scanning electron microscopy, transmission microscopy. Titanate as starting materials exhibit higher chemical reactivity, regarded a structure template for retaining one-dimensional final products calcination. formation related to ion-exchange reaction Ostwald ripening process due high reactivity nanorods. galvanostatic charge/discharge tests conducted measure electrochemical performance It demonstrated that 800°C have excellent rate discharge capability good cycle stability during insertion extraction processes, owing crystallinity, unique structure, short diffusion distances originated morphology.
