1. A method for making a carbon nanotube-transition metal oxide composite, comprising:
step 1, providing at least one carbon nanotube obtained from a super-aligned carbon nanotube array;
step 2, pre-oxidizing the at least one carbon nanotube;
step 3, dispersing the at least one carbon nanotube in a solvent to form a first suspension;
step 4, dispersing a material containing transition metal oxyacid radicals in the first suspension to form a second suspension; and
step 5, removing the solvent from the second suspension and drying the second suspension to form the carbon nanotube-transition metal oxide comprising the at least one carbon nanotube and a plurality of transition metal oxide nanoparticles, wherein the plurality of transition metal oxide nanoparticles are chemically bonded to the at least one carbon nanotube through carbon-oxygen-metal linkages, wherein the metal is a transition metal element.
