Synergistic effect of amorphous carbon coverage and enlarged voltage window on the superior lithium storage performance of nanostructured mesoporous anatase TiO2: Emphasis on interfacial storage phenomena.

Highlights: [•] Interconnected agglomerates of nanoparticles are assembled into a porous network. [•] Both bulk insertion and interfacial storage contribute to the high capacity. [•] The enlarged voltage window of 0.01–3.0V is employed firstly. [•] An ultrathin carbon layer (1nm thick) helps to avoid the structure instability. [•] The obtained nanoparticles have a high capacity of 270mAhg− 1 at 300th cycle. [ABSTRACT FROM AUTHOR]
