1-6mm Diameter 99.99% High Purity Gold Electrode

In the battery, electrode generally refers to the redox reaction occurs and the electrolyte solution position. The electrode is divided into positive and negative, generally positive as anode, electron gain, reduction reaction occurs, the negative cathode oxidation reaction occurs, the loss of electronic. The electrode can be metal or non metal, as long as they can exchange electrons with the electrolyte solution, which become the electrode.

In electrochemical analysis solution concentration, electrode is converted into an electric signal sensor.
