Reshape the Future of Energy. With Us.
At Skellium, we’re not just building better batteries — we’re redefining what’s possible for electric mobility. Based in Aachen and backed by the EXIST Research Transfer programme, we’ve developed a breakthrough manufacturing process for ultrathin lithium-metal anodes that makes next-generation solid-state batteries safer, more efficient, and ready for scale. Think: EVs with 1,000+ km range. That’s the world we’re building.
We’re a small, ambitious team at the very beginning of something big — and we’re looking for a Bachelor’s or Master’s student who wants to be part of it.
Bachelor’s / Master’s Thesis | Influence of Storage Conditions on Lithium-Metal Anode Quality
Your Mission
Lithium-metal anodes are a key technology for future high-energy batteries. Their high reactivity with oxygen, moisture, and nitrogen, however, makes safe and reliable storage a major challenge. You will systematically investigate how storage atmosphere, temperature, and duration affect the surface chemistry, interfacial resistance, and electrochemical performance of Skellium’s ultrathin lithium-metal anodes.
Your work will help establish clear acceptance criteria and practical storage recommendations for our production process.
What You’ll Work On
- Design and conduct a systematic aging study under defined storage conditions
- Store lithium-metal anodes in an argon glovebox, dry room, and at elevated temperatures over different periods
- Characterise the samples using electrochemical methods such as EIS, stripping/plating, and full-cell testing
- Investigate surface properties using analytical methods such as XPS and SEM
- Correlate storage parameters with surface chemistry, interfacial resistance, and electrochemical performance
- Derive acceptance criteria and actionable recommendations for Skellium’s production and storage processes
Who You Are
- Currently enrolled in Mechanical Engineering, Materials Engineering, Chemistry, Electrochemistry, or a comparable programme
- Interested in hands-on experimental laboratory work
- Structured, independent, and reliable in the way you approach technical problems
- Curious about complex challenges and excited to work at the frontier of battery technology
- A team player who communicates openly and contributes to a collaborative start-up environment
What You Get
- Real responsibility from day one in an early-stage deep-tech start-up
- A clearly scoped thesis with flexible implementation
- Professional academic and technical supervision
- Hands-on experience with advanced lithium-metal anodes and analytical methods
- The opportunity to turn your results into concrete production recommendations
- Direct insight into building and scaling a battery-technology company
