▎ 摘　　要

NOVELTY - The method involves adding graphite oxide in water and mix solvent of ethanol to obtain oxidized graphene suspension. Rear graphene oxide suspension liquid is added in a lithium titanate nano-granule. Mass ratio of a lithium titanate oxide graphene-carbon nano-tube is 15-120: 120: 5-60. Temperature of the lithium titanate oxide graphene-carbon nano-tube is heated upto 90-130 degrees Celsius in reducing agent. A solid product is obtained by a reaction system for reducing graphene oxide. A rear part of a lithium titanate graphene-carbon nano-tube composite material is dried. USE - Method for manufacturing a lithium titanate-graphene-carbon nano-tube composite material of a lithium ion battery (all claimed). ADVANTAGE - The method enables improving conductivity of a lithium titanate oxide graphene-carbon nano-tube so as to reduce diameter of the lithium titanate oxide graphene-carbon nano-tube. The method enables improving circulation property and multiplying power property of the lithium titanate graphene-carbon nano-tube composite material, so that energy storage electric potential can be improved. The method enables improving circulation and stability of a lithium ion battery.
