PAT-Cell-Force
Operando test cell to adjust and measure the mechanical force applied to the cell stack
Our PAT series test cell especially suitable for the investigation of solid state electrolytes
The PAT-Cell-Force is a special operando test cell of the PAT series for the adjustment and measurement of the mechanical force applied on the cell stack. Thanks to the wide force range, the cell is suitable for both aprotic Li-ion battery chemistries with liquid electrolytes and solid state setups. The force on the cell stack can be set to up to 1500 N when assembling the cell and then monitored during the electrochemical cycle. Additional sensors allow for the simultaneous monitoring of gas pressure and temperature.
The modular PAT-Core concept warrants easy and efficient handling and enables 3-electrode measurements with a ring-shaped reference electrode when using liquid electrolytes. The PAT-Cell-Force is to be operated with an EL-CELL potentiostat like the PAT-Tester-x. All sensor signals are recorded and displayed in EL-Software.
Its advanced sealing concept with welded-in sensors and glass-to-metal sealed electrode feedthroughs make the PAT-Cell-Force perfect for stable long-term measurements. The PAT-Cell-Force is equipped with an electronic cell tag (PAT-Button) for automatic recognition in EL-Software.

Cycling of NCM 111 vs Graphite in a PAT-Cell-Force
EL-CELL offers metal sealing rings for PAT series test cells for highest demands on cell tightness. This tool kit is designed to ensure the correct installation when using these metal seals. The handy assembly block holds the cell in place, while the torque wrench allows you to close the cell cover with the recommended amount of force.
Product details
Lid springs
The spring force applied to the cell stack is:
- 105 N ±10% if used with aluminum lid seal
- 115 N ±10% if used with PE lid seal.
These values apply to an upper electrode thickness ranging from 0 to 0.8 mm. Within this range, the electrode thickness has no significant influence on the force.
