Description of PhD project
The main focus of the project is to evaluate the commercial potential of TiO2 as an alternative anode material in Li-ion batteries. TiO2 nanoparticles are synthesized in different polymorphs, sizes and morphologies, and characterized by a range of techniques. Their structural properties are related to the synthesis methods and electrochemical performance in half- and full-cells. Furthermore, structural and mechanical properties during charging and discharging is investigated. The performance is benchmarked against commercial carbonaceous and Li4Ti5O12-based anode materials.
Biography
Martin Søndergaard obtained his Master and Ph.d. degrees in materials chemistry from Aarhus University in 2009 and 2013, respectively, under the supervision of Professor Bo Brummerstedt Iversen.
His main research focus has been synthesis and characterization of inorganic thermoelectric materials. He is currently employed at Aarhus University as an industrial postdoc in a collaboration with Haldor Topsøe A/S. In this project the main work consists of synthesizing electrode materials for Li-ion batteries and relating the synthesis method to the structural and electrochemical properties.
