001020575 520__ $$aIn recent years, metal–air batteries have been gaining much attention as one crucial line of development as promising energy storage devices due to possessing high theoretical specific energies and energy densities while utilizing cost-effective, safe, and environmentally friendly electrode materials. Among various possible metal–air configurations, mostly Zn–, Fe–, and Al–air have been the research focus for many decades. Up to now, Ti has not been considered as an active anode material, although it is a light metal that can possibly transfer up to 4 electrons. The reason behind this is that the electrochemical behavior of Ti is known for its passivity in various media and, also, it is conceptually mistaken as an expensive metal (∼5 times cheaper than Li-hydroxide (as a Li source)).Herein, we report a novel non-aqueous primary Ti–air battery utilizing 1-ethyl-3-methylimidazolium oligofluorohydrogenate (EMIm(HF)2.3F) room temperature ionic liquid as electrolyte. Initially, the electrochemical behavior of Ti was studied by potentiodynamic polarization, which revealed the first insights into its electrochemical activity. Subsequently, the galvanostatic discharge experiments were conducted to evaluate the performance of Ti–air batteries in full-cells. The battery could successfully be operated under relatively high current densities (up to 0.75 mA/cm2) with an average cell voltage of 1–1.2 V, yielding up to a discharge capacity of 66 mAh/cm2. Post-mortem characterization of the electrode surfaces was performed by SEM in combination with EDS to analyze the potentially deposited discharge products. Furthermore, ICP-OES and FTIR techniques were employed for investigating the electrolytes to gain further insights into the possible mechanisms leading to cell discharge termination over time. Accordingly, the possible reaction mechanisms governing within the cell were proposed for such a novel Ti–air battery. Such a metal–air battery holds a unique potential to be the only metal with 4 electrons transfer during its discharge once its full potential is harvested.
