▎ 摘　　要

NOVELTY - The preparation of lithium titanate/activated graphene nanosheet composite material involves adding graphene nanosheet and titanium dioxide in mass ratio of 1:(5-20), adding lithium hydroxide solution, stirring at room temperature, ultrasonically treating to completely disperse, transferring the mixed solution into high-pressure hydrothermal kettle, reacting at 140-220 degrees C for 0.5-24 hours, naturally cooling at room temperature, centrifuging and washing, blow drying to obtain black sample, adding dried sample into argon tube furnace, and calcining at 500-1000 degrees C for 1-10 hours. USE - Preparation of lithium titanate/activated graphene nanosheet composite material (claimed) used in lithium ion battery cathode. ADVANTAGE - The method enables preparation of lithium titanate/activated graphene nanosheet composite material with high electrochemical performance and high capacity retention rate, and avoids the use of organic titanium sources and organic solvents. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for lithium titanate/activated graphene nanosheet composite material.
