What is your role in the team at the Institute of Science and Technology (ISTA) and how has it evolved during MeBattery? My role at ISTA has always been preparing and characterizing new materials, but at some point, I have also been partially assigned to do some basic electrochemical characterization to help out the team in studying the materials when more hands were needed. Now that we have established the general protocols for preparing the materials and since my colleague Mario Palacios Corella left ISTA to take a postdoctoral junior fellowship by “La Caixa Foundation” in Barcelona, I continue to do the remaining tasks in the project on my own.
Why is this field of research so exciting? I think it is so exciting since a lot of things are still not really clear when it comes to Prussian blue analogues (PBAs), especially for the anodic ones. This kind of search for the answers, which leads to revealing new knowledge, is always challenging and fascinating.
What are the advantages for young researchers working in an EU-funded project? Working in an EU-funded projects gives you the great advantage of having a wide and reliable network of collaborators with the same ultimate goal. I think that having a group of people at ISTA and in the project with huge knowledge in the field and with the same final objective really makes the difference in science.
What impact, do you think, will MeBattery have on the European energy sector? That is a very interesting question. For me, at this point, it is impossible to predict how good the final prototype of the battery developed in the project will be. But I think that the fundamental idea of the project, the use of abundant materials to which there is access in the EU and the aim of developing greener alternatives, will show the general guidelines to be followed by the sector in the future.

What is your role in the MeBattery team at UBU? What expertise did you acquire from your involvement in MeBattery? Within the MeBattery team at Universidad de Burgos, the principal task I am investigating in is the confinement of the solid booster in the external reservoir. As I started my PhD at the same time as the project started, I have acquired knowledge about energy storage especially about redox flow batteries at the same time as I also learned several advanced electrochemical techniques.
After almost two years of MeBattery, what would you consider your major achievements? After nearly two years with MeBattery, our major achievements lie in the successful confinement of booster materials, leading to significantly higher efficiency in battery performance. However, we are still working on optimizing some variables of the booster such as porosity and size. What does it mean to you to be part of the MeBattery project? Being part of MeBattery is an opportunity to contribute to advancements in stationary energy storage which is crucial for the transition to renewable energy sources. Moreover, being involved in a Pathfinder EU project is really useful for international collaboration and for building relationships with other research groups. How do you see the field of sustainable batteries evolving in the future? The ecological transition will increase the demand of batteries for various applications such as electric vehicles or stationary energy storage for renewable energy sources. For mobility applications lithium ion batteries will still be the best option, for a more sustainable approach recycling technologies will be developed. For stationary energy storage, redox flow batteries that are based on non-critical materials are mandatory if they are to be implemented at large-scale (MWh), including mediated redox flow batteries that are the ones proposed in MeBattery.

What is your research focus at IST Austria? At IST Austria we are developing new functional micro and nanomaterials that can be used as electroactive units in the battery. This work involves the chemical design and synthesis of the materials with a proper combination of organic ligands and metallic centers, but also the characterization of the material after its preparation to confirm the composition and purity.
Why is this field of research so exciting? The field is very exciting due to its intrinsic idea. The battery materials that we are developing for MeBattery are free of many toxic and critical elements like cobalt. In general, the use of such elements has a very important impact on the lives of the citizens. By getting rid of these elements, we aim to achieve more sustainable batteries that can compete with current technologies while lowering the environmental cost.
Is this your first experience working on an EU-funded project? What is your opinion about this programme? It’s not my first involvement in an EU-funded project, but it is my first involvement in a Pathfinder EU project. I think that the European Commission is doing a really good job by funding these innovative high-risk high-reward concepts that all in all aim to have a major impact in society.
How do you see the field of sustainable batteries evolving in the future? It is very hard to say as the field is very broad and divided into concepts that are different from each other each other. For example, there is a special interest in fully organic batteries that do not require the use of metals at all, and these are very exciting. But there’s also merit in the recent development of Zn-Air batteries, which have shown that can deliver a lot of power. Overall, the field should evolve in a direction where the economic and environmental costs are reduced to the minimum.
