摘要

A mixed solvent is prepared by dissolving acetic acid and lithium acetate in a mixture of isopropanol and water. This mixed solvent together with titanium alkoxide and carbon nanofiber (CNF) were introduced into a rotary reactor, the inner tube was rotated at a centrifugal force of 66,000 N (kgms -2 ) for 5 minutes to form a thin film of the reactant on the inner wall of the outer tube, and sheer stress and centrifugal force were applied to the reactant to allow promotion of chemical reaction, yielding CNF on which highly dispersed lithium titanate nanoparticle precursors are supported. The obtained composite powder was heated under nitrogen atmosphere at 900°C for 3 minutes, yielding a composite powder in which highly dispersed lithium titanate nanoparticles are supported on CNF, wherein crystallization of lithium titanate was allowed to progress.
