The ideal test cell for high-throughput battery testing.
Our electrochemical standard test cell for two and three-electrode testing.
The PAT-Cell is the test cell for high-throughput testing of battery materials. The PAT-Cell has no sockets for direct cable connections. It must therefore be used with a docking station such as the PAT-Stand-1 or PAT-Stand-16. This enables parallel battery tests to generate more reliable test results with less effort and in a shorter period of time.
The PAT-Cell and the PAT-Stand-16 are a solution for medium and large battery test laboratories with more than 10 test cells running in parallel. Moreover, the PAT-Cell increases the testing productivity through easy handling and it saves space in the lab.
Long term tests
The PAT-Core enables battery tests with a three-electrode setup of a duration of 1000 hours and more. The reason for this advantage is the new ring-shaped Li-reference electrode, which is far more time stable than point-type reference electrodes.
This makes the PAT-Core the perfect test system for aging studies.
Less cross contamination
The single-use concept of the PAT series helps to reduce cross-contamination between subsequent tests and corrosion issues. The PAT-Core consists of three single-use parts: insulation sleeve (PP), upper plunger (Cu as standard) and lower plunger (Al as standard). All these parts are assembled, packed and sealed under controlled atmosphere at the EL-CELL® factory. Moreover, it is not required to clean and dry the single-use parts, which avoids the risk of contamination with water and reduces effort in the lab.
Please note that upper and lower plungers are also available as reusable versions in stainless steel.
Half-cell impedance spectra
The results of half-cell impedance spectroscopy reach a new level with the new PAT-Cell. The ring-shaped Li-reference electrode allows half-cell impedance tests with minimal artifacts, due to the well-defined geometry of the insulation sleeve.
Easy electrolyte filling
The PAT-Cell can be filled easily with electrolyte during the assembly procedure. The user needs only an usual micro pipette for this purpose to drip a defined amount of electrolyte onto the separator, which is factory preinstalled in the insulation sleeve of the PAT-Core.
The amount of the electrolyte used is typically between 50 and 200 μL, depending on the thickness and porosity of the electrodes and separator used.
Tight test cells
The PAT-Cell is completely airtight. This is ensured by the special PE-Seal clamped between the double cutting rings of the cell lid and cell body. This sealing concept guarantees ultra-low leakage and enables the operation of the PAT-Cell outside of the glovebox.
The new PAT series improves the productivity of battery testing. The single-use concept avoids effort for cleaning and disassembling the PAT-Cores. When used with a PAT-Stand-16, it saves time for connecting the test cells with the potentiostat for every new battery test. Moreover, the PAT-Stand-16 saves space in the lab through the compact design for up to 16 PAT-Cells. All these features increase the battery testing productivity and facilitate high-throughput testing.
