Luleå University of Technology is involved in several of these cutting-edge research projects and in the societal transformation that they entail. We offer a broad range of courses and study programmes to match the skills in demand. We hope that you will help us to build the sustainable companies and societies of the future.The Division of Chemical Engineering is searching for a researcher within the research subject Chemistry of Interfaces with a research focus on synthesis and characterization of halogen-free and non-flammable electrolytes for batteries.

Subject description
Chemistry of Interfaces deals with both experimental and theoretical aspects of the heterogeneous processes that occur at interfaces between liquid, solid and gas phases, as well as with the development of novel surface-sensitive analytical techniques for studying these processes at the molecular level.

Project description
Conventional electrolytes are solutions of fluorinated lithium salts dissolved in organic solvents. Such electrolytes have a number of drawbacks including toxicity, high flammability, high vapour pressure, and low thermal and electrochemical stabilities. There is therefore an urgent need to replace these electrolytes with non-flammable and halogen-free alternatives in order to improve both safety and performance. Ionic liquids are salts that are liquids at or below 100 °C and possess a number of unique properties such as non-volatility, non-flammability, high thermal stability, high ionic conductivity, high chemical and electrochemical stability and functional designability. Due to this, ionic liquids are considered as a suitable component for future electrolytes. However, most of the commercially available ionic liquids and salts contain fluorinated anions making them less environmentally benign, expensive and cumbersome to produce and also problematic in the recycling stage. Therefore, development of new non-flammable and high performant electrolytes is highly desirable.

Duties
As a researcher you are expected to perform both experimental and theoretical work within your research studies as well as communicate your results at national and international conferences and in scientific journals. Most of your working time will be devoted to your own research studies. As a researcher, you work as a neutral party in many contexts, which provides a great opportunity to be involved in challenging development projects.

The main focus here is to design, synthesize and characterize halogen-free and non-flammable electrolytes. The target is to start from readily available, economic and green materials using benign synthetic procedures. The resulting electrolytes will be characterized using multinuclear NMR, FTIR, and Raman spectroscopic techniques. In addition, physicochemical properties such as density, viscosity, thermal behavior, and ionic conductivity, together with electrochemical stability and battery performance will be measured.

Qualifications
In order to be eligible, you must have a PhD degree in chemistry and a good knowledge of and experience in organic synthesis and physicochemical characterization. You as a researcher should be very good in written and spoken English. Experience in synthesis of electrolytes, and physical and electrochemical characterization is considered as an advantage.

Further information
Employment as a researcher is limited to 6 months. Placement: Luleå. Starting: upon agreement.
