PAT-Cell-Gas-HT
Battery test cell for heating the cell stack to 400°C and analyzing the produced reaction gases
The PAT-Cell-Gas-HT
The PAT-Cell-Gas-HT is an in-situ battery test cell designed to simulate thermal runaway by heating the cell stack to temperatures up to 400° Celsius while simultaneously analyzing the reaction gases produced.
The cell base is thermally decoupled from the measurement electronics, and the heating element is positioned directly beneath the cell stack. Temperature control is managed through EL-Software, allowing for easy script-controlled temperature changes and ramps.
The reaction gases generated are channeled from the cell base to the carrier gas system and mixed via a bypass/Laval nozzle. This setup ensures that the carrier gas does not come into contact with the cell stack, thereby preventing the cells from drying out. The carrier gas system connects to the cell using Swagelok quick-connect fittings.
Additionally, there is a closable septum port for sampling and injecting reactants into the cell base.
The cell stack inside the PAT-Cell-Gas-HT uses 18 mm electrodes and the PAT-HT-Core, a customised variant of the modular PAT-Core system. A reusable ceramic insulation sleeve is used here for operation at 400°C. The stainless steel plungers have also been modified to facilitate disassembly for post-mortem analysis of the cell components. These components are fully compatible with other PAT series test cells as well.
Please note: The PAT-Cell-Gas-HT is a development study, not a finished product. The shown specifications refer to the current development stage.
Gas Flow System
The illustration shows the addition of the reaction gases to the carrier gas system using a Laval nozzle. Separating the carrier gas flow from the cell base prevents the electrolyte from being carried away and the cell from drying out.
