Morphology Controls and Lithium Battery Performances of Titanate Nanostructures Synthesized by Hydrothermal Process

Abstract

Titanate nanostructures were prepared from alkaline hydrothermal process with mechanical milling and sonication treatments. By the post-treatments, the morphologies of titanate nanostructure were controlled and the contributable sites for Li-ion absorptions were increased. The effects of post-treatment was confirmed by X-ray diffraction, HR-TEM and BET surface area analyzer. The nanostructures were fabricated to the coin cell 2032 and the battery performances were investigated.
