Product Description
The PAT-Cell-Force is a specialized operando test cell that enables adjustment and measurement of the mechanical force applied to the cell stack. With a wide force range of up to 1700 N, a pressure of up to 60 MPa can be applied on the cell stack, depending on the electrode diameter. This makes the PAT-Cell-Force ideal for characterizing solid-state batteries, but it can also be used for other aprotic lithium-ion battery chemistries with liquid electrolytes.
The PAT-Cell-Force uses the patented PAT-Core system to build perfectly aligned cell stacks. For liquid electrolytes, PAT-Core components with 18 mm electrode diameter are available for performing 2- and 3-electrode measurements. Please note that the PAT-Cell-Force uses a special variant of the upper plunger.
For solid-state electrolytes, a new variant of the PAT-Core, the PAT-Solid-Core, is available. This variant is specifically designed for measurements on solid-state batteries and features carbide plungers and PPS insulation sleeves. In conjunction with the new Solid-State Pressing Device, the solid-state test specimen can be pressed directly in the PAT-Solid-Core.
The PAT-Solid-Core is available in various electrode diameters (6 and 10 mm). If used inside the PAT-Cell-Force, this allows a load of up to 60 MPa to be applied to the cell stack during assembly and monitored throughout the entire electrochemical cycle. In addition, built-in sensors enable simultaneous monitoring of gas pressure and temperature.
An EL-CELL potentiostat, such as the PAT-Tester-x-8 or PAT-Tester-i-16, is required to cycle the PAT-Cell-Force. The use of the PAT-Terminal-1 is recommended for precise force adjustment before each experiment. All sensor signals are recorded and transmitted digitally in real-time for plotting in EL-Software.
The PAT-Cell-Force is directly connected to the EL-CELL potentiostat or docking station via a cable-free connection. This accelerates experiment setup and reduces signal noise. Thanks to its advanced sealing design, the PAT-Cell-Force is ideal for stable long-term measurements. In addition, the device is equipped with an electronic cell tag (PAT-Button) for automatic recognition in the EL-Software.
