西班牙圣帕布洛大学化学方向博士后职位

CEU San Pablo University (CEU) was founded in Madrid in 1993 and it is ranked as the second private university in Spain in research effort. CEU counts with 7 Research Centers, 40 research units and 11 research support services. Currently CEU is developing more than 50 research projects, with a budget that exceeds € 4 million. The University has an increasing history of collaboration with Industry, meaning around 65% of its R&D funding. CEU is looking for a highly motivated candidate to apply for a Marie Skłodowska-Curie Individual Fellowship - Postdoc position. Together with the selected candidate a MSCA IF proposal will be written and submitted. The involvement of the selected candidate in the proposal writing process will provide ample opportunity to tailor the proposal to his / her research interests. A successful application will result in a two-year appointment.
 

Description

The hosting Group is the Solid State Chemistry and Materials Research Group of CEU, working on intercalation materials for lithium ion batteries since 1995 and more recently on sodium ion batteries. The Group has a very complete laboratory for carrying out those research tasks covering the whole process from the synthesis of active materials to prototyping of pouch cell up to 2 Ah. Our Group collaborates with several Spanish research Groups through National Integrated Projects and also with international Groups in USA, UK, Germany, France, India and Japan. Through these collaborations we largely extent the available characterization techniques to those needed in some cases for a full understanding of the electrochemical behavior of target materials. We also collaborate with Industry regarding mainly, but no only, the prototyping of lithium ion cells for aeronautics. The activities of the Marie S. Curie Fellow will focus on the search of new titanates as anode materials for safer batteries with improved capacity and cyclability. Safety is perhaps one of the most important issues for electrical vehicles and aeronautical applications, among others. The use of titanates in lithium batteries eliminates the risks of metallic lithium dendrite formation. Besides voltage operation of titanates is within the stability window of common electrolytes. Thus, titanium oxides and lithium titanates provide a wide selection of safe and long life anodes for lithium ion batteries. The work will comprise the synthesis, structural characterization by XRD, NPD, SXRD, TEM, etc., processing optimization and electrochemical characterization to determine specific capacity, specific energy, cyclability, etc. of electrodes. Selected materials will be used to build lithium ion prototypes of up to 2 Ah using a standard cathode material. Fabrication of several units will be completed in order to assemble battery packs to be integrated in aerial platforms in collaboration with an aeronautical Research Centre. Alternatively to the standard positive electrode to be combined with titanates, new high voltage positive electrode materials will be explored among the less investigated and still interesting transition metal oxyfluorides. In this case, new synthetic methods avoiding the use of the toxic hydrofluoric acid will be applied and the full characterization from structural to electrochemical accomplished.
