PAT Series Overview

Our modular system for testing of battery materials

Our modular system for testing of battery materials

The PAT series contains battery test cells, docking stations and battery testers with integrated temperature chambers and a sophisticated testing software, in short all devices needed to perform efficient research of battery materials.

The equipment is easy to use and still flexible enough to easily adapt it to unique test requirements. The main purpose of the PAT system is to improve the workflow from experiment design to results analysis. Recurring work, such as converting test set-ups, rewiring test cells, and programming test procedures, is kept to a bare minimum, which significantly reduces the risk of user errors. This in turn frees up more time for the user to fully focus on the experiment.

We strongly believe that reliable and simple 3-electrode measurements are the most efficient way to develop new battery materials. As a consequence, all PAT test cells are designed for long-term measurements with three electrodes. You can record the electrical properties of the full cell and both half cells simultaneously with just one test run. These features significantly reduce the time and effort involved in testing compared to 2-electrode cells, such as commercially available coin cells.

The PAT system offers prefabricated single-use components for high-throughput testing as well as reusable components for smaller tests and tests involving special requirements.
Other workflow enhancements, including the cableless design as well as digital cell recognition through the new PAT button, attest to our commitment to providing battery researchers with reliable and easy-to-use tools.

The power of testing with a reference electrode

By monitoring the cell voltage and cell current of the battery, you can learn a lot about the performance and ageing of the battery as a whole.
However, a battery comprises two electrodes connected in series: cathode and anode. Which of the two is the bottleneck for charge transfer? Which electrode is dying off first? Using a reference electrode is the most convenient way to answer these questions.

The insulation sleeve of the PAT-Core is available with different built-in reference rings and separators. For Li-ion based systems we consider Li metal together with the polyolefin based separator FS-5P as a favorable solution. Many variants of the insulation sleeve are available for other battery chemistries including Mg, Na-ion and supercapacitors.

When used with a powerful battery tester such as the PAT-Tester-i-16, the reference electrode enables you to measure the electrochemical properties of both electrodes at the same time.
