Understand Cell Safety in Unprecedented Detail
Our proprietary DATRC enables you to fully capture your battery cell thermal runaway, enabling you to identify risks early.
Fully Quantify the Thermal Runaway Behaviour of a Single Cell
Our proprietary test method quantifies the following parameters with a single test.
-
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 gas produced in the thermal runaway
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
Interactive Example: Similar Cells, Different Safety Behaviour
Average data for three 2170 cell types, 4.9 Ah each, triggered by overheating (10 °C/min). Average values for three repeats per type.
Significant differences in the amount of energy remaining in the cell after thermal runaway are observed. Similarly, the amount of released gas, as well as the release rates vary significantly.

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.
