CompreCell 12-DP
highly reliable 3 Electrode test cell for studying solid-state-batteries
Test cell for studying solid-state batteries in 2- and 3-electrode configuration
The CompreCell 12 DP is a measurement cell suitable for measuring multilayer stacks of solid samples, like all-solid-state batteries, under active pressure control. It is also suitable for powdered samples and allows e.g. pelletizing in-situ.
An intuitive design facilitates the layer-by-layer assembly of an all-solid-state battery starting from the separate component materials: Both hard metal plungers in the cell can move independently and therefore apply pressure to a stack at a fixed position in the inner sleeve. This allows for measuring sample stacks that are sensitive to vertical movement and minimizes the risk of cracking and short-circuits through the layers.
As sleeve material, AlOx, PEI, and PEEK are available. The fixed location of the sample also facilitates the use of a solid-state reference electrode for 3-electrode measurements. On demand, we could also provide a version for 6 mm diameter samples (CompreCell 6 DP). The CompreCell 6 DP can only be operated in 2-electrode configuration due to limited space.
Specifications and content
The CompreCell 12-DP is the ideal solution for the layer-by-layer assembly of solid-state batteries and allows for studying them in a 2- or 3-electrode configuration at different stack pressures and temperatures:
- Cycling of solid-state batteries under active stack pressure and temperature control
- Pressure- and temperature-dependent investigation of a solid-state electrolyte’s conductivity
- Stripping-plating experiments under actively controlled stack pressure

In–Li Counter Electrodes in Solid-State Batteries – A Comparative Approach on Kinetics, Microstructure, and Chemomechanics
A recent publication by Alt et al. in Advanced Energy Materials describes an investigation by the Janek research group into the usage of InLi as a counter electrode in solid-state battery (SSB) research. They studied the impact of the preparation method on the potential stability, rate capabilities, and microstructure of the electrode. Furthermore, they used the CompreDrive to quantify the cell height changes as an effect of lithium insertion and extraction during cycling.
Three-Electrode All-Solid-State Battery Cycling
Why include a reference electrode in battery testing?
A reference electrode makes it possible to distinguish between cathode and anode processes that otherwise overlap in a two-electrode measurement. In this application note, the separate potentials of the NMC cathode and the graphite anode could be monitored during cycling, and impedance spectra could be recorded simultaneously for both electrodes, as a function of temperature.
