In a two electrode setup the current carrying electrodes are also used for sense measurement.
For example, when connecting to a battery or fuel cell, the positive electrode (cathode) should be considered the working electrode and connected to the RED/ORANGE pair while the negative electrode (anode) should be connected to the GREEN/WHITE pair.
Figure 2: Two-electrode cell setup Two-electrode experiments measure the whole cell, that is, the sense leads measure the complete voltage dropped by the current across the whole electrochemical cell: working electrode, electrolyte, and counter electrode.
Most investigations on novel materials for Li- and Na-ion batteries are carried out in 2-electrode coin cells using Li- and Na-metal as the negative electrode, hence acting as counter and reference electrode.
Different battery cell setups, including so-called “ half-cell ”, “ symmetrical-cell ” and “ full-cell ” setups as well as two-electrode or three-electrode configurations, are described in the literature to be used in the laboratory for the electrochemical characterization of battery components like electrode materials and electrolytes.
Due to the considerable need for highly reproducible cells, which basically differ in the electrolyte additive, machine-made electrodes and cells produced by battery manufacturers are highly recommended, e.g., as often reported by Dahn et al. , , , , , , .
