A Scaling Model for Electrolyte Filling of Lithium-Ion Batteries

Electrolyte filling is a key and time-critical step in lithium-ion battery cell manufacturing. This dissertation investigates the wetting behavior of porous electrode and separator materials and develops a scalable simulation model based on experimental characterization.

The study focuses on material-dependent and process-relevant factors influencing wetting. It demonstrates how these influences can be systematically described and transferred to larger cell formats.

By combining physical process understanding, experimental characterization and application-oriented process simulation, the dissertation provides approaches for the efficient design and optimization of industrial electrolyte filling processes.
