This product is designed for reliable and stable electrochemical testing of coin cells, particularly in techniques such as electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The sealed fixture ensures a corrosion-resistant environment for assembled cells, minimizing contamination and improving measurement consistency. It supports CR20 cells with thicknesses ranging from 1.5 to 3.5 mm and CR24 cells from 2 to 4 mm, with custom dimensions available on request. The fixture’s rotatable design allows adjustment to various angles, accommodating different cell geometries and facilitating flexible test setups. Constructed from durable, corrosion-resistant materials, the sealed chamber enhances long-term accuracy for research-grade battery diagnostics. This fixture is ideally suited for laboratories focused on battery material characterization and electrochemical performance evaluation.
