Lithium titanium oxide (LTO)/carbon composite, preparation method for LTO/carbon composite, negative electrode material using LTO/carbon composite, and hybrid super capacitor using negative electrode material

A lithium titanium oxide (LTO)/carbon composite comprising:

• an LTO granule agglomerate composed of a plurality of LTO granules, the LTO granule agglomerate having a plurality of voids between neighboring LTO granules, the LTO granules being made of Li4Ti5O12, and having a particle diameter of 50 to 400 nm and a specific surface area of 10 to 300 m2/g;
• and
• a carbon-based additive inserted into the voids, the carbon-based additive comprising at least one selected from the group consisting of activated carbon, graphene and carbon aerogel.
