Optimizing the rate performance and cycle life of Li 2 MTi 3 O 8 (M = Mn, Co, Zn)/CNTs for lithium-ion battery anodes by constructing a one-dimensional carbon-based hybrid structure.

One-dimensional nanohybrids Li 2 MTi 3 O 8 /CNTs (M = Mn, Co, Zn), i.e. , Li 2 MTi 3 O 8 nanoparticles embedded in carbon nanotubes, were synthesized by following a combination of methods involving sol-gels, solid phase grinding and calcination. As anodes for lithium-ion batteries, Li 2 MTi 3 O 8 /CNTs (especially Li 2 CoTi 3 O 8 /CNTs) exhibited superior electrochemical performance.
