Product Description
Introducing the PAT-Cell-Press II, an innovative 3-electrode battery test cell designed to measure the expansion of reaction gases during electrochemical cycles!
This test cell is equipped with advanced digital pressure and temperature sensors that transmit data via a reliable I²C interface to the EL-Software, allowing for real-time data plotting. The PAT-Cell-Press II S variant also features a septum connection for drawing gas samples for further analysis. Its wireless connection to the potentiostat reduces interference signal and minimizes setup time.
With laser-welded sensors, glass-to-metal electrode feedthroughs, and metal seals, the PAT-Cell-Press II ensures maximum cell tightness against the ambient atmosphere. It utilizes the modular PAT-Core system, providing flexible and time-saving cell stack configurations suitable for both aprotic and aqueous electrochemistry.
The PAT-Cell-Press II replaces the previous PAT-Cell-Press. It is designed for use with EL-CELL potentiostats to take full advantage of all sensor functions.

Frequently Asked Questions
Which cell is right? PAT-Cell-Press or PAT-Cell-Gas?
How can I identify whether my PAT-Cell is suitable for use with metal seals?
Many test cells in the PAT series are already supplied with a metal seal lid (Item name: Screw cap insulated (PAT)) as standard. If you still have an older cell, you can use the following features to determine whether the existing cover is suitable for metal seals.
The compatible cell lid for use with metal seals has two holes on the top and a white or black inset made of PPS in the lid, which serves as insulation.
As the two holes can also be found on older cell lids without insulation, you should always check whether the inset is present. Non-compatible cell lids have no inset at all.
Do you need a PAT-Press-Box to operate the PAT-Cell-Press II?
The PAT-Cell-Press II transmits its signal data via the digital I²C bus and therefore does not require any additional devices. Please note that an EL-Cell potentiostat is required to read out the pressure and temperature sensor signals.

Frequently asked questions
How can I identify whether my PAT-Cell is suitable for use with metal seals?
The compatible cell lid for metal seals (Item name: Screw cap insulated (PAT)) can be recognized by two features. It has two holes on the top and a white or black inset made of PPS in the lid, which serves as insulation.
As the two holes can also be found on older cell lids without insulation, you should always check whether the inset is present. Non-compatible cell lids have no inset at all.
Do you always need a PAT-Press-Box to operate the PAT-Cell-Press?
The PAT-Press-Box is required to read and record the analog pressure signal of a PAT series test cell.
It is required in the following docking stations:
The following devices provide the necessary functions themselves, therefore no PAT-Press-Box is required:

This tool kit is designed to ensure the correct installation when using metal lid seals.
Compression spring , FED 9079
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 *.
Compression spring , FED 9052
The spring force applied to the cell stack is 7 N ± 30% *.
*Spring force 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.

Aqueous electrolytes
The PAT-Cell-Press withstands all common aqueous electrolytes such as sulfuric acid and potassium hydroxide solution. Due to its excellent corrosion resistance, the PAT-Cell-Press can also be used for aprotic systems beyond Li-ion. We recommend using PEEK current collectors for these applications as shown below:
Specialized PAT-Core with reusable plunger made of PEEK polymer and gold current collectors (optionally other metals such as Pt, Ni)
