PAT Series Overview
Learn more about our perfectly matched system of testing devices for the research of battery materials
Our comprehensive, modular system for testing new battery materials
With the PAT series, we are the first supplier worldwide to offer you a complete system consisting of test cells, potentiostats and control software that are perfectly matched to each other. This makes testing battery materials more efficient, more reproducible and easier to use than ever before.
PAT series test cells
The PAT docking stations
In order to connect and operate a PAT-Cell with a potentiostat, the cell is simply inserted into the socket of a PAT docking station. Only the docking station itself is permanently wired to the potentiostat, the PAT-Cells themselves are cableless. In this way, the connection to the potentiostat no longer has to be renewed and checked before each test.
In principle, all PAT-Cells can be used in any docking station to test basic electrical properties such as capacity and impedance. The only exception is the high temperature docking station, the PAT-Heater-4, which can only be used with specially designed PAT-Cell-HT test cells.
Many docking stations also support additional functions of the more specialized members of the PAT series, such as the measurement of the gas pressure with the PAT-Cell-Press.
The main difference between PAT docking stations is the number of connection sockets for the test cells. The smallest docking station, the PAT-Clamp-1, has a single socket, the largest ones offer space for up to 16 PAT-Cells. The PAT-Chamber-16 also offers an integrated temperature chamber to test PAT-Cells at temperatures between +10 and +80° Celsius.
PAT docking stations can be connected and operated with all currently available potentiostats or battery cyclers.
The PAT battery testers
We have incorporated our long-standing practical experience with electrochemical testing into the development of a new generation of battery testers, the EL-CELL PAT tester series. Our focus is on convenient handling and minimising laboratory space as much as possible through high integration of core components and a modern system architecture.
Each test channel of a PAT battery tester contains a fully equipped potentiostat / galvanostat and impedance analyser as well as new, unique features. A switch matrix facilitates alternating between full-cell and half-cell control at runtime without having to change even a single cable. In an unprecedented way, impedance measurements may be combined with cyclic voltammetry and constant current cycles.
Two different product lines, based on the same system architecture, offer a variety of application options:
The PAT-Tester-i-16, a highly integrated device, combines a temperature controlled chamber, a docking station for up to 16 PAT-Cells and the battery tester with 16 fully equipped test channels. Minimal space requirement makes the PAT-Tester-i-16 the perfect solution for high-throughput test scenarios.
The PAT-Tester-x-8 is the perfect solution whenever maximum flexibility is required. Up to 8 test cells can be tested simultaneously in very different environments with this device: on the laboratory bench, in the glovebox, in a climatic chamber, or wherever else you want. The electronics of the single channel are identical to the one in the PAT-Tester-i-16. This guarantees the highest performance, not only for PAT-Cells, but also for all other EL-CELL test cells as well as for coin cells and a variety of other cell formats.
EL-Software is the newly developed software solution from EL-CELL to plan, perform and evaluate experiments with the PAT battery testers. The software enables networked, location-independent operation with a scalable number of test channels and devices.
All relevant data, like cell components, script procedures or the resulting measurements, are written into a central, conveniently searchable database. This growing data treasure is accessible for all users in the same network and helps to speed up the process of experiment planning and interchanging of test data significantly. With the powerful yet easy-to-use test composer you can set up virtually any battery procedure, from simple voltammetric experiment to a complex test that combines constant current cycles at different C-rates with intermittent impedance measurements.
In batch mode, any number of test procedures can be performed sequentially, either for a single test cell or for a group of test cells – all this without writing a single line of code.
Available control modes are constant current, constant voltage, open circuit, linear voltage sweep, galvanostatic and potentiostatic impedance.
Finally, EL-Software provides you with state-of-the-art graphics capabilities for visualizing your test results, while the open export interfaces allow seamless integration into existing software pipelines.
