Analysis of gases emitted by batteries
Identify and quantify gaseous emissions from your batteries under normal or abusive conditions
The Emitech Group offers a comprehensive service for analysing the gases emitted by batteries, modules or cells, as part of functional, abuse or ageing tests.These analyses are used to characterise the nature, quantity and hazardousness of the gases released during normal operation, thermal runaway or electrical or mechanical failure.

Why analyse the gases emitted by batteries?
In the event of overheating, overcharging or damage, lithium-ion batteries or other technologies may release :
- Flammable gases (H2, CH4, C2H6, etc.),
- Toxic compounds (CO, HF, HCN, volatile hydrocarbons),
- Corrosive agents (HF, SO2, NOx),
- Organic vapours with an irritant or environmental effect.
- Assess the health and environmental risk,
- Qualify the materials and internal components,
- Plan ventilation, containment or neutralisation systems,
- Meet standards requirements (R100.3, UL, ISO, etc.).
What are the applications?
Electric and hybrid vehicles.
Stationary and industrial storage.
Aerospace, naval and military applications.
Fleets of batteries for urban, rail or agricultural mobility.
The analysis methodology used in the Emitech Group laboratories
Test conditions
- Functional tests, severe cycling, overload, short-circuit, thermal runaway.
- Tests in confined enclosures with automatic sampling system.
- Gas detection during emission and post-test.
Analytical resources available
- GC-MS (gas chromatography-mass spectrometry): identification of volatile organic compounds (VOCs).
- FTIR (Fourier Transform Infrared Spectroscopy): continuous measurement of gas composition (CO2, CO, HF, HCl, NOx, etc.).
- Electrochemical and optical sensors: real-time monitoring (H2, CO, O2, temperature, pressure).
- Gravimetric analysis: mass of gas emitted, loss of matter, relative concentration.
Deliverables: Summaries and test results
- Emission curves by component.
- Quantification in ppm, mg/m3 or g/cycle.
- Time profile of off-gases.
- Comparison with regulatory or industrial thresholds.
