Toward a Better Understanding and Optimization of the Electrochemical Activity of Na-Ion TiO₂ Anatase Anodes Using Uniform Nanostructures and Ionic Liquid Electrolytes.

ABSTRACT: TiO₂ anatase has emerged as a promising anode for Na-ion batteries (SIBs). However, widespread use of this anode is severely limited by a series of factors that need to be identified and understood to further improve their electrochemical response. Here, we have taken benefit from the versatility of a self-assembly seeding-assisted method to obtain a variety of uniform high-surface-area undoped TiO₂ anatase nanostructures. Electrodes built from these uniform nanostructures in combination with a safe ionic liquid electrolyte have allowed a systematic study on some of the factors that determine the electrochemical activity of Na-ion anatase anodes. Interestingly, the inherent low penetrability of the ionic liquid electrolyte has resulted in an unexpected asset to clarif
