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 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 Master’s student who wants to be part of it.
Master’s Thesis | Passivation Layer — Lithium-Metal Anodes
Your Mission
Lithium-metal anodes are among the most promising — and most challenging — materials in next-generation battery technology. Highly reactive by nature, their performance and safety hinge on what happens at the surface. You will tackle this challenge head-on by systematically investigating how targeted passivation layers can be formed, controlled, and optimised on lithium-metal anodes — and translate your findings directly into Skellium’s production process.
What You’ll Work On
- Experimentally implement and compare different passivation approaches, including CO₂ atmospheres (Li₂CO₃) and fluorine-containing additives (LiF)
- Characterise the resulting surface layers using SEM, XPS, and optical microscopy
- Evaluate electrochemical stability and performance for each passivation method
- Draw direct comparisons between approaches to identify the most promising routes
- Develop concrete recommendations for targeted surface passivation in the context of Skellium’s anode production
Who You Are
- Currently enrolled in an Engineering programme (Industrial Engineering preferred) at a top European university
- Solid understanding of the battery market and its key dynamics
- Structured and self-driven — you take ownership and follow through
- Curious about complex problems and energised by the idea of working at the frontier of deep tech
- A team player who communicates openly and contributes to a collaborative culture
- Proficient in PowerPoint, Word, and Excel
What You Get
- Real responsibility from day one in an early-stage deep tech start-up
- Direct access to founders and industry experts
- Flexible working arrangements and clearly scoped tasks
- The chance to shape Skellium’s strategy — your thesis won’t sit in a drawer
- A front-row seat to building a company from the ground up
