Description
Summary:Anatase TiO 2 nanocrystals were successfully employed as anodes for rechargeable Na-ion batteries for the first time. The mesoporous electrodes exhibited a highly stable reversible charge storage capacity of ∼150 mA h g −1 over 100 cycles, and were able to withstand high rate cycling, fully recovering this capacity after being cycled at rates as high as 2 A g −1 . Anatase TiO 2 nanocrystals were successfully employed as anodes for rechargeable Na-ion batteries for the first time.
