Energy StorageOn page 3522, Y. Yu and co-workers fabricate nitrogen-doped ordered mesoporous TiO 2 nanofi bers (denoted as N-MTO) by electrospinning and subsequent nitridation treatment.Nitrogen atoms are successfully doped into the TiO 2 lattice, accompanied by the formation of Ti 3+ and oxygen vacancies, contributing to the improvement of electronic conductivity of TiO 2 .When used as an anode for a sodium-ion battery, the N-MTO demonstrates excellent rate capability and superior long cycling performance.
