METHOD FOR PREPARATION OF COMPLEX OF LITHIUM TITANATE AND CARBON NANOTUBE

摘要

PURPOSE: A method for manufacturing a lithium titanium oxide-carbon nano-tube composite material is provided to stably form lithium titanium oxide on carbon nano-tubes of low electric resistance and a specific pore structure. CONSTITUTION: A method for manufacturing a lithium titanium oxide-carbon nano-tube composite material includes the following: Lithium salt is dissolved in a solvent at the weight ratio of 1:80 to 120 to obtain a first solution. Tetra titanium iso-propoxide is dissolved in the solvent at the weight ratio of 1:40-60 to obtain a second solution. The first solution and the second solution are mixed to obtain a third solution. Carbon nano-tubes are dissolved in the solvent at the weight ratio of 1:40-100 to obtain a fourth solution. The third solution and the fourth solution are mixed to obtain a fifth solution. Polyvinyl pyrrolidone is added into the fifth solution to obtain a sixth solution. Ultrasound wave is applied to the sixth solution to disperse the carbon nano-tubes. The solvent is eliminated from the sixth solution with dispersed carbon nano-tubes. A plasticizing process is implemented under nitrogen atmosphere.
