▎ 摘　　要

NOVELTY - Preparation of titania/three-dimensional graphene composite electrode material, involves ultrasonically treating the graphene oxide with glycolic acid and titanyl sulfate to obtain a mixed solution, heating the mixed solution to 180 degrees C, hydrothermally reacting for 12 hours, solid-liquid separating, washing and drying the solid, and calcining for 4 hours at 450-700 degrees C. USE - Preparation of titania/three-dimensional graphene composite electrode material for battery (all claimed) e.g. lithium ion battery. ADVANTAGE - The method enables simple preparation of composite electrode material, which improves the discharge specific capacity and cycle stability of batteries.
