Product overview

Product description

Our pressure test cell for the PAT series

The PAT-Cell-Press is a pressure test cell for measuring gas evolution and drawing gas samples (option). Its advanced design includes a laser welded pressure sensor and glass-to-metal seals. The number of non-permanent seals is reduced to its minimum: a single PE seal between cell lid and base and a ferrule when the cell is ordered with the optional gas sample port.

In order to ensure best testing results, every PAT-Cell-Press is intensively tested for helium leaks.

Features

PAT-Core design with or without reference electrode

Laser welded pressure sensor, 0 to 3 bar abs

Electrode feedthroughs with glass-to-metal seals

Helium leak tested

Superior corrosion resistance against aqueous electrolytes (e.g. H₂SO₄, KOH). Also applicable to aprotic battery chemistries with special demands on corrosion resistance

Optional gas sample port (PAT-Cell-Press S)

Optional upper plunger for gas diffusion electrodes

Optional high volume lid for increased inside gas volume

Analog outputs for pressure and temperature (+-10V) for seamless integration with other instruments

Optimzied lid for use with metal seal

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)

Frequently asked questions

PAT-Cell-Press

Which cell is right? PAT-Cell-Press or PAT-Cell-Gas?

The PAT-Cell-Gas is most appropriate for experimental set-ups with continuous gas flow. If only the pressure change of the inside gas volume is to be monitored over time without continuous gas supply, the PAT-Cell-Press is the easiest choice.

	PAT-Cell-Press	PAT-Cell-Gas (P, S, SP)
Cell is dedicated to:	The quantitative (cumulative) measurement of the gas evolved / consumed during the electrochemical cycle by measurement of the gas pressure	Time resolved analysis of the gas evolved / consumed during the electrochemical cycle in combination with a mass spectrometer and controlled gas supply
Preferred operation mode:	Pressurized cell without gas flow	Flow-through with gas analysis at outlet and mass flow controller at the inlet
Plug flow:	not available	Almost perfect when using the lower plunger with flow field; significant back-mixing when using the lower plunger with perforated plate
Applicable to:	• Aprotic chemistries such as Li-ion, Li-air, super cap • Some aqueous chemistries may work, but compatibility must be checked by the user	• Aprotic chemistries such as Li-ion, Li-air, super cap • Some aqueous chemistries may work, but compatibility must be checked by the user
Upper electrode:	Any compatible electrode, either self-standing or with metal foil current collector; standard upper plunger or perforated upper plunger	Any compatible electrode; often Li metal or LFP are used here as a Li ion source; preferably there is no gas evolution or consumption at this electrode
Lower electrode:	Any compatible electrode, either self-standing or with metal foil current collector; standard lower plunger or perforated lower plunger	The lower electrode is seated on a plunger with flow field and must therefore be gas permeable, either self-standing or on current collector mesh. The gas evolution / consumption at the lower electrode is subject of the measurement.

Our pressure test cell for the PAT series

In order to ensure best testing results, every PAT-Cell-Press is intensively tested for helium leaks. It is used with the PAT-Stand-1 docking station or in multi-channel configuration in the PAT-Chamber-16.

PAT-Press package

The PAT-Press is a complete single cell package for recording the pressure rise during battery formation and cycling, and for drawing gas samples from the headspace of the test cell. For testing with multiple PAT-Cell-Press test cells we recommend using the PAT-Chamber-16 or PAT-Tester-i-16.

Accessories

Metal seal mounting kit, (Order no.: ECC1-02-0040-A)

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.
