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.
锡掺杂的二氧化钛纳米管被用作钠离子电池的阳极。在50 mA g(-1)的电流密度下循环50次后，电极表现出257 mA h g(-1)的高最大充电容量，具有良好的倍率性能，尤其是出色的循环稳定性，这主要归因于锡掺杂提高了电导率。
