Electrochemical performance of porous TiO₂ microspheres coated with nitrogen-doped carbon as an anode material for lithium-ion batteries.

ABSTRACT: TiO₂ has a robust structure and low cost and is non-toxic. However, its low electronic conductivity and lithium-ion diffusivity impede its practical application in LIBs. To improve the conductivity and lithium-ion dynamics of titanium dioxide (TiO₂), we synthesized porous TiO₂ microspheres coated with nitrogen-doped carbon (TiO₂@C-N) through a solvothermal method combined with pyrolysis and carbonization technology. The nitrogen-doped carbon coating was prepared using a one-pot sealed carbonization method with pyrrole as the source of carbon and nitrogen. The porous TiO₂ matrix in the TiO₂@C-N composites provided numerous open transport pathways and storage sites for Li ions, while the nitrogen-doped carbon coating promoted
