Abstract

Batteries are ubiquitous in daily life. Sodium-ion batteries have the potential to become inexpensive alternatives to the current market products such as Lithium-ion batteries. TiO₂ nanotubes have proven potential as an anode for Na-ion batteries. Electrolytes made by NaClO₄ salt and carbonate-based solvents make up commonly used electrolytes in sodium ion battery research. We used electrochemical and physical characterization tests to evaluate the optimum electrolyte for this anode material in the Na system. We determined that the ClO₄^- ion decomposes at the TiO₂ surface and promotes the formation of an unstable solid electrolyte interphase. A salt more stable than NaClO₄ needs to be researched in the electrolyte for future use with TiO₂ anodes in sodium-ion batteries.
