Pressure frame for studying solid-state electrolytes and solid-state batteries under pressure and for sample pre-pressing in CompreCells

The ComPrep can be used to operate cylindrical CompreCells under pressure, for sample pre-pressing in CompreCells and for sample removal if necessary.

Compatible with all types of cylindrical CompreCells
Torque-based force application
Electrically insulates the test cell, offers 2 mm and 4 mm female connectors.
Small and cost-efficient solution to operate CompreCells in temperature chambers.
Parallelize your measurements

Typical applications

Load or unload your CompreCells for use in CompreDrive or CompreFrame, or use the ComPrep directly as preparation and pressure frame. Directly connect a potentiostat.

Pre-pressing of powder materials in CompreCells in a glove box
Easy and reliable removal of pressed pellets from CompreCells
EIS or cycling of CompreCells under pressure in temperature chambers

Detailed Description

The ComPrep is compatible with the CompreCell 6/12 and the CompreCell 6/12-DP as well as the three electrode options.

It is a manually operated pressure frame that comes with a torque wrench. The combination of a high-precision trapezoidal spindle and bearing bronze ensures a reliable and reproducible torque-based force application.

The optimized footprint and the compliance temperature range makes it the ideal solution for testing of many cells in parallel.

As a single unit, it fits every budget.

The electrochemical device (cycler, potentiostat, impedance analyzer) can directly be connected to the ComPrep and the CompreCell using banana connectors.
