The spinel Li4Ti5O12/rutile-TiO2@carbon (LTO-RTO@C) composites were fabricated via a hydrothermal method combined with calcination treatment employing glucose as carbon source. coating layer and the in situ formed rutile-TiO2 can effectively enhance electric conductivity provide quick Li+ diffusion pathways for Li4Ti5O12. When used an anode material lithium-ion batteries, rate capability cycling stability of LTO-RTO@C improved comparison those pure Li4Ti5O12 or Li4Ti5O12/rutile-TiO2. Moreover, potential approximately 1.8 V rechargeable full batteries has been achieved by utilizing LiFePO4@N-doped cathode.
