Influence of Storage Conditions on Lithium-Metal Anode Quality

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
