Researcher Solid State Batteries
What you will do
Lithium-ion is the technology of choice for rechargeable battery applications as the Li-ion electrode chemistries provide the highest volumetric and gravimetric energy density known. Since its first introduction on the market by Sony in 1991, it took about 20 years to triple the energy density from 200Wh/L to 600Wh/L mainly by improvements in the electrode formulations. This evolution was primarily driven by the advent of portable electronics such as the smart phone. In the last few years, we have seen a push in energy density with the introduction of new electrode materials with higher intrinsic Li-ion storage capacity. State-of-the art cells today reach nearly 700Wh/L. This second wave in Li-ion technology developments is driven by the emerging electrical vehicle market. It is expected that further improvements can bring us to 800Wh/L in the first part of the 2020’s. For the next generation batteries, targeting 1000Wh/L, it is generally agreed that Li-metal anodes in combination with all-solid-state concepts will be needed. At imec, we are developing high conductivity solid nanocomposite electrolytes for solid-state Lithium and Li-ion batteries. For the integration of the first generations, we are using similar cathode and anode materials as currently used in wet batteries. In a next step, lithium metal anodes will be considered.
For these new technologies focus lays on interface control and engineering to enable safe and fast charging, and this throughout the entire cell lifetime. In the team, you will:
- Be scientifically responsible for the “Interface and interphase R&D platform” in which artificial interphase are being developed by means of thin-film deposition and characterization techniques
- Integrate these artificial interphases in real secondary Li-ion and lithium metal cells by (co-)developing a high-throughput atomic layer deposition (ALD) technique
- Be a project lead for existing bilateral and/or public funded projects in the team
- Assist in the writing of new project proposals together with the scientific/technical management of the team
What we do for you
We offer you the opportunity to join one of the world’s premier research centers in nanotechnology at its headquarters in Leuven, Belgium. With your talent, passion and expertise, you’ll become part of a team that makes the impossible possible. Together, we shape the technology that will determine the society of tomorrow.
We are proud of our open, multicultural, and informal working environment with ample possibilities to take initiative and show responsibility. We commit to supporting and guiding you in this process; not only with words but also with tangible actions. Through imec.academy, 'our corporate university', we actively invest in your development to further your technical and personal growth.
We are aware that your valuable contribution makes imec a top player in its field. Your energy and commitment are therefore appreciated by means of a competitive salary with many fringe benefits.
Who you are
- We are looking for candidates who have experience in thin-film deposition and characterization. Experience with Li-ion cell technology, nanoionics and electrochemistry is a plus. Furthermore, you are a self-motivated scientist or engineer, who seizes opportunities and is enthused by new challenges.
- You have a PhD degree in science or engineering and deep knowledge on ALD and preferably PVD (i.e. magnetron sputtering and thermal evaporation)
- You have experience in electrical and/or electrochemical characterization
- You have experience with project management and/or (public funded) project writing
- You take initiative and work independently, while being part of a team, you can guide and motivate team members in their work, you can plan the work of a team according to deadlines and deliverables
- You are creative and like to think with the team to solve problems
- You are result-driven and can meet stringent deadlines with quality output.
- You are flexible to accept new challenges in the future, and to evolve together with the changing R&D demands of our high-tech environment
- The imec environment requires a good team player with competent communication and reporting skills. Given the international character of imec an impeccable knowledge of English is mandatory.
