An electrolyte for energy efficient magnesium electrolytic cells

The new generation cells for magnesium metal extraction such as bipolar cells are energy efficient. In such cells, the electrolyte composition plays a major role in obtaining pure metal with less energy consumption. To identify such an electrolyte, a series of experiments have been carried out with alkali and alkaline earth chlorides. A ternary composition consisting of magnesium chloride, sodium chloride and potassium chloride has been found suitable.
