▎ 摘  要

A Li-4 Ti-5 O-12 (LTO) -graphene (G) hybrid with a flaky structure was fabricated by solvothermal treatment of a suspension of graphene oxide (GO), lithium hydroxide and tetrabutyltitanate in 1-methyl-2-pyrrolidinone, followed by calcination of the solid product at 700 degrees C for 1 h. GO as the precursor of graphene is amphiphilic and acts as an anionic surfactant and template for the growth of LTO under alkaline conditions to form the flaky LTO-G hybrid with a high crystallinity. Compared with the material without GO, the LTO-G has a typical flaky morphology and exhibits a much higher capacity and betterrate capability.
