Cell Development and Testing
Institute for Applied Materials – Energy Storage Systems (IAM-ESS)
In the field of cell development, the construction of highquality
lithium-ion pouch cells are in focus in the laboratory and
industry-related large format.
Cell Assembly
Semi-automatic line for manual manufacture of pouch cells in
the dry room:
- Analysis of failure mechanisms with forced cell failures
- Performance analysis of cell components, such as separator, electrodes, conductor foils
- Tests of new electrolytes and additives
- Tests of new active materials
- Tests of new cell formats
Cell Tests
Electrochemical characterization of cells of any format
(hard case, pouch and round cells):
- Rate capability and internal resistance
- Endurance tests and application of load profiles
- Calendar aging tests
- Electrochemical impedance spectroscopy
Post-mortem Analysis
Investigation of aging phenomena or cause and effect
relationships:
- Light and electron microscopy
- HPLC and GC measurements of electrolyte constituents
- (at IAM-ESS: X-ray analysis, XPS, etc.)
