Résumé
A three electrode cell for use with solid electrolytes is presented. The cell provides a stable reference voltage and leads artefact-free impedance spectra while being easily assembled and airtight. To prove its versatility several combinations of electrodes and electrolytes were employed, enabling to rapidly assess the main differences between argyrodite vs. lithium phosphorous sulphide electrolytes, oxide vs. sulphide active materials or Li-In alloy based anode vs. Li foil anode. This new cell design offers a simple and efficient way of identifying the proper electrode-electrolyte components for enhancing solid state battery performances.
