Cell Analysis Capabilities at FEV’s European Sites

At multiple facilities in Europe, FEV has highly specialized battery cell capabilities and infrastructure.

The FEV Battery Cell Lab in Aachen has the capability to benchmark battery cells in terms of their performance, safety, and design.

FEV’s battery cell lab for benchmarking and analysis based on cell opening and teardown as well as the fabrication and testing of prototype cells.

FEV’s battery cell lab enables in-depth analysis based on electrical and safety testing as well as cell opening and teardown procedures.

Overview of the FEV’s Battery Cell Laboratory

FEV Aachen has advanced capabilities in the field of battery abuse testing for battery cells, especially ARC.

Exemplary Analysis

A cross sectional EDS analysis of the anode reveals that it consists of a composite of graphite and SiOx.

A high capacity 169 Ah NMC prismatic cell was tested with two different trigger methods to measure absolute gas volume generation and gas flow.

A 169 Ah NMC prismatic cell was destroyed to measure absolute gas volume generation and gas flow (“Nail Penetration” Test) as input for simulation.
