GERMANY - Teams with Israel on Titanium-Air Battery

Arno Froese

Metal-air batteries are particularly suitable for applications in which a compact size is important or in large-scale stationary storage systems that use low-cost, common and nontoxic materials. Titanium-air batteries theoretically have two to three times the energy density of zinc-air batteries, which are used today as standard button cells in hearing aids, control modules and sensors.

The development of the new battery concept was carried out in close cooperation between Dr. Yasin Emre Durmus, from the Jülich Institute for Energy and Climate Research (IEK-9), which is headed by Prof. Rüdiger-A. Eichel, and Prof. Yair Ein-Eli, from the Technion-Israel Institute of Technology in Haifa, who spent a seven-month sabbatical at IEK-9 as part of the Umbrella Cooperation of Forschungszentrum Jülich in Germany, the Technion and RWTH Aachen University (the largest technical university in Germany).

Titanium is known as a passive, stable material. The researchers succeeded in using its electrochemical potential for the storage of electrical energy by applying an ionic liquid called EMIm(HF)2.3F. Ionic liquids consist of salts with an atypical, very low melting point that are used in a variety of applications due to their special electrical and material properties.

In metal-air batteries, the contained metal reacts with the oxygen in the air to release electrical energy. This type of battery thus occupies a special position among batteries because one of the two reaction partners, oxygen, is obtained from the ambient air via a special electrode and does not have to be kept in the battery. As a result, much higher energy densities can be achieved with these systems than with common battery types, at least in theory.

The team published their findings in the Chemical Engineering Journal under the title “Exempli gratia non-aqueous Ti–air battery.”, 29 March 2023

Arno's Commentary

The goal is energy storage, and energy is something the world needs exponentially. According to, the percentage of energy is divided as follows: oil, 33.1%; coal, 27%; gas, 24.3%; renewable sources, 11.4%. One of the hurdles to maintaining a reliable supply of energy is one word: storage. Here Professor Durmus, a Turkish Muslim, teams up with Professor Yair Ein-Eli, an Israeli Jew, to solve or at least contribute to having a stable energy solution. 

The ultimate source of power lies in the Creator. Proverbs 8:14 proclaims: “Counsel is mine, and sound wisdom: I am understanding; I have strength.”
