Who we are
|
Our mission has started. We are starting our own battery cell production in Battery Valley in Salzgitter and ramping up our headquarters for global cell production. The CTO organization takes care of the battery cell development. Our responsibility includes research, predevelopment of materials and components, series development, prototyping, testing and analysis of battery cells.

Your role and key responsibilities
|
Large Language Models (LLMs) are transforming human-computer interaction. Their application in data‑analysis workflows holds tremendous potential, yet remains under‑explored. This PhD dissertation will investigate how LLMs can be efficiently integrated into daily engineering and development processes.
The overall objective of the PhD Thesis will be:
- How can an LLM‑based “battery expert” be trained so that its knowledge becomes effectively accessible to engineers in battery development?
Depending on your interests, the dissertation may address questions such as:
- Which architectural or adaptation patterns (Knowledge Graphs, RAG, Agents, Fine‑Tuning) are most effective in method development?
- How can the quality of LLM‑generated analyses be evaluated (e.g., hallucination detection)?
- How can LLM decision‑making be better understood, monitored, and controlled?
