Test equipment makes the difference

The possibility to control independently temperature and pressure on a pouch cell while cycling it is something unique in the research field and on the market. With our equipment we are able to measure phenomena and their dependency from temperature and pressure that were only theorized in literature.

Investigation of the piezoelectrochemical transducer effect with respect to temperature

The application of a mechanical pressure on a Li-ion battery leads to a variation of the open circuit voltage. The effect is similar to the one of piezoelectric materials. However, the amplitude of this effect and its dependency from the pressure level and temperature is still not exaustively quantified in literature.

Calibration of a phenomenological thermo-electro-mechanical model based on a variation of the HPPC test

Building a digital twin of a battery can be challenging when coupled models are calibrated from different test setups. With our system we can define a single sensitivity study with a HPPC test protocol and model the thermo-electro-mechanical behavior of the cell.

Analysis of the breathing phenomenon with respect to temperature and pressure

The breathing phenomenon is a well known process that leads to reversible expansion of a Li-ion cell due to intercalation and de-intercalation of Li-ions in the anode structure. In order to quantify the amount of expansion and its dependency from temperature and average pressure level, a phenomenological study must be conducted.

Sensitivity study of electrical performaces with respect to pressure and temperature

The electrical performances of a pouch Li-ion battery were investigated under different conditions of temperature and pressure. This study has been successfully published in a peer review journal.

Analysis of the swelling phenomenon with respect to temperature and pressure

The irreversible expansion of Li-ion cells during their life, known as swelling, must be investigated with respect to the working temperature and the average applied pressure.

Influence of pressure and temperature on the open circuit voltage curve

The open circuit voltage curve of a Li-ion cell varies if the temperature of the cell changes, this is a well known phenomenon in literature. However, how this voltage variation changes in its amplitude together with the pressure, has not yet been investigated.
