Abstract

Sn-doped TiO₂ nanotubes were employed as anodes for sodium ion batteries. The electrodes exhibit a high maximum charge capacity of 257 mA h g⁻¹ after 50 cycles at a current density of 50 mA g⁻¹ with good rate capability and especially excellent cycling stability, mainly due to the increase of electrical conductivity by Sn doping.
