Anode; Anode

Electrode where an electrochemical oxidation reaction takes place; it captures the electrons given up by chemical species to supply them to the external electrical circuit; it corresponds to the negative electrode of a discharging accumulator and vice versa.

Cathode; Cathode

Electrode where an electrochemical reduction reaction takes place; it transfers electrons from the external electrical circuit to the chemical species; it corresponds to the positive electrode of a discharging accumulator and vice versa.

Cellule électrochimique ; Electrochemical cell

Electrochemical device, consisting of a positive electrode, a separator and a negative electrode, sharing the same electrolyte, which generates electricity by converting chemical energy into electrical...
