Fully Quantify the Thermal Runaway Behaviour of a Single Cell

Our proprietary test method quantifies the thermal runaway event of a cell. Each experiment determines the relevant properties that characterise the cell behaviour.

    • Total energy released in the thermal runaway event

    • Energy fraction remaining in the cell

    • Energy fraction released with the ejected gas and solid particles

    • Total amount of gas produced by the thermal runaway reaction

    • Vent gas temperature

    • Amount of solids ejeted from the cell and size distribution

    • Vent gas release rate during the thermal event, both average and peak rate

    • Solids release rate, both average and peak rate

    • Thermal power of the energy release

Understand Safety-Critical Edge Cases

Lithium
Plating

By comparing the DATRC results of pristine and lithium-plated cells, the effects on safety can be understood early in development.

Cell Ageing
& SOH

By comparing the energy and gas released of pristine and aged cells, expensive safety testing on module/pack level can be avoided.

Vent Gas
Combustion 

By executing DATRC tests in both air and inert gas, the effect of vent gas combustion with atmospheric oxygen can be determined empirically.
