"Electrode composition and process definition for evaluation of novel ion conductor – material composites for electrochemical energy storage"

Pedro López-Aranguren / Experienced Researcher at SAFT in Bordeaux, France

Working title

Electrode composition and process definition for evaluation of novel ion conductor – material composites for electrochemical energy storage.

Objectives

Lithium batteries commonly used involve the use of a flammable organic liquid electrolyte which can be too hazardous for applications where the battery size is large. In this context, the substitution of liquid electrolyte by an inorganic solid electrolyte is considered as the best solution to overcome the already mentioned problem.

The work on this topic can be summarized into four main objectives: i) the definition of electrode composition, ii) the design of a process compatible with solid electrolyte, iii) the study of the reactivity of the new materials and the low production cost and iv) the techno-economical evaluation of electrochemical performance.

Tasks and methodology

The solid electrolyte and electrode materials will be integrated into battery half cells. The synthesis of the electrolyte and electrode mechanical will be performed by methods such as ball milling and reactive ball milling. The synthesized materials will be characterized using solid state tools such as XRD, DSC, TGA, spectroscopic tools (i.e.,FTIR, Raman Spectroscopy), etc. Performance of the assembled batteries will be studied using a wide range of electrochemical techniques.

Short CV

My name is Pedro López-Aranguren and I was born in Madrid on 1986. I studied Chemistry at the Faculty of Science at the Universidad Autónoma de Madrid. After obtaining my degree I moved to Barcelona to start a PhD at the Instituto de Ciencia de Materiales de Barcelona (ICMAB-CSIC). My PhD was focused on the use of Supercritical Fluids to develop advanced organic-inorganic hybrid materials for adsorption applications. In November 2014 I finished my thesis entitled “Functionalized Adsorbent Materials Using Supercritical CO2”. Results from my work in materials science have been published in a number of journals https://www.researchgate.net/profile/P_Lopez-Aranguren.

I enjoy very much working in the field of materials science because it is always a challenge that requires the combination of knowledge and creativity to develop materials with new properties for practical applications. During my free time I enjoy very much going to the mountains, doing photography and cooking.
