Advanced Cell Testing
What cell testing we offer
We partner with our clients to create customised testing projects that fit your needs. Our team works closely with you to ensure quality results, delivered rapidly. Contact us to learn more.
Characterisation & Performance testing
We focus on electrically cycling the cell under various conditions, enabling you to see the changes in cell behaviour as the cell age and degrade.
​
Conditions can include:
-
Thermal cycling via forced air convection or surface cooling
-
Drive cycle testing to mimic real world usage
-
Fixed gap or pressure cell compression​​​​​​
Storage testing
Storage testing enables you to analyse the changes in cell behaviour due to calendar ageing degradation mechanisms. Conditions can include:
-
Various states of charge
-
Air cooling/heating via forced air convection thermal chamber
-
Storage in compression fixtures to mimic pack conditions
-
Periodic voltage measurements to measure self discharge
Our equipment
Testing is done within our labs in forced air convection thermal chambers, ranging from -40 to 180°C. Cell cycler makes include Basytec, Ivium, Maccor & Neware.
All our equipment is regularly serviced and calibrated to ensure the data we provide you is top quality.

​
As standard, we supply:
-
Visualised dashboards for cell data
-
Customised data delivery formats
​
Data will be supplied in your preferred way, at times specified by your bespoke project plan (e.g. weekly).
Bespoke test fixtures
Our in-house engineering team and workshop can rapidly design and fabricate custom cell test fixtures.
Examples include:
-
4690 cylindrical cell testing up to 200A
-
1Ah pouch cell testing with and without compression
-
50Ah pouch & 100Ah prismatic cell testing with compression
-
Pouch cell archimedes principle expansion measurement
