 Can you hear me? Okay. Hello everyone, I'm Lorenzo Grande from ID TechX and I'm here with Dr. Elia, who is a senior researcher at the Technical University of Berlin, and he focuses on unconventional battery chemistry. Is that right? Yeah. We actually are focusing on the development of an aluminum battery system and trying to find a way to overcome the issue of the possibility of the limitation of the lithium resource. In fact, considering the chance to have a complete electric fulfillment of the market by electric vehicles, there are some prospective that say that the lithium will be not enough. So we have the problem to find the alternative electrochemical system using much more abundant elements and that can be sodium, magnesium, potassium and aluminum. In particular, our activities focus on aluminum since it's the most abundant metal on the earth crust due to its three valencies characterized by the really elevated energy density and it has a volumetric energy density that exceeds four times the one of lithium system. Wow, that's amazing. That will be a great advantage. Clearly, the system is still in this infancy. The real development of such system starts more or less one years and a half ago. So we are really, really at the beginning, but there are a lot of space to make improvement and to try develop some good systems. Yes, and your lab was one of the first in the world to start working on this chemistry. Yeah, actually the first research comes from the very famous Stanford paper in nature about the aluminum battery system. They clearly demonstrated that it's possible to make a battery out of aluminum that is unbelievable because it's a really stable metal. We use it to pack the food and use it in a battery to make a reversible electrochemical process. It's something that is really particular and but now we found the condition to make it possible and we need to improve it to make it bring it to the real market. Do you have one? Great. Not yet. Not yet. Not yet. In three years, four years, maybe. Okay, and in terms of energy density and average voltage, what numbers do you disclose? The point is that clearly the voltage of the aluminum system is much lower and it's a 2.5 volt lower respect of lithium. Basically we cannot believe to beat lithium in terms of energy density. Okay. There are some space to try to reach lithium in terms of volumetric energy density since we can one of the main advantages that for this system you can use directly aluminum metal. That is not possible for a lithium system. So in the development of a real battery pack this will be a great advantage because we'll be enough a few microns of aluminum foil to sustain the capacity of cathode material. The problem is the cathode material that the only one that is suitable until now is the graphite with a limited capacity that is one-third of the conventional lithium-ion system that leads to the actual aluminum battery system that can be developed. It has an energy density in the range of the nickel metal hydride batteries. Okay, and you will be talking about your research this afternoon in the Track 7. Yeah, actually I'm involved in a European funded project. It's a lion with the work that involves several industrial partner research institutes and we are trying we are we have some collaboration also with the Helmholtz Institute in Berlin to make some more research on this topic. So we are quite confident that in the following years we will be able to find something that is good. Wow, this is great. And are you enjoying the ID TechLex show so far? Yes, the first time and it's really great, really huge. The exposition is really impressive. Also they talk as well. And the food is really good. Okay, we're very glad to have you here. Okay, thanks a lot.
