PAT-Cell-Press-Aqu
Pressure test cell for aqueous electrolytes and non-lithium battery systems
The PAT series pressure test cell for special demands on corrosion stability
The PAT-Cell-Press-Aqu is the aqueous version of the PAT-Cell-Press. The special design can withstand all common aqueous electrolytes such as sulfuric acid and potassium hydroxide solution.
By default, current collectors are made of gold. Other metals such as Pt and Ni are available as an option. Due to its excellent corrosion resistance, the PAT-Cell-Press-Aqu can also be used for aprotic systems beyond Li-ion.

PAT-Press-Aqu Package
The PAT-Press-Aqu 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-Aqu test cells we recommend using the PAT-Chamber-16 or PAT-Tester-i-16.
