英文摘要	Graphene-encapsulated Li2MnTi3O8 nanoparticles were synthesized via a modified sol-gel process using graphene oxide as the template. The prepared Li2MnTi3O8 material has a complex spinel structure in the P4(3)32 space group. The morphology of the graphene-encapsulated Li2MnTi3O8 composite indicates that the Li2MnTi3O8 particles can be uniformly scattered on a graphene substrate, and these particles have a size of 10-20 nm. The electrochemical properties indicate that the graphene-encapsulated Li2MnTi3O8 material possesses a stable reversible discharge capacity of similar to 220mAh g(-1) after 50 cycles at 0.1 C. In addition, the reversible capacity at 2 C improved by 70% after graphene-encapsulation, which indicates the excellent high rate capability. (C) 2014 Elsevier Ltd.
