Conflat Two and Three Electrode Electrochemical Cells

Abstract

Two and three-electrode electrochemical test cells based on low cost and readily available Conflat vacuum fittings are described. Two-electrode Conflat cells were found to have the same performance as two-electrode coin cells at room temperature, while three-electrode Conflat cells are much easier to assemble than three-electrode coin cells. Such cells maintain good stack pressure, tolerate high vapor pressure solvents and can operate at temperatures up to 200°C. Conflat cells are especially useful for high temperature and magnesium battery research, where the need for three-electrode cells operated at elevated temperatures with volatile solvents makes the use of coin cell hardware impractical.
