Question

What is the full equation of the redox system of Sb (Antimon) and Mg (Magnesium) in a liquid metal battery with molten salt?

Answer 1

Answer 2

touch of background intel. Sb has an ElectroNegativity of 2.0 Mg has an EN of 1.3 the molten salt is simply the electrolytic situation for electron transfer.

anode side: Mg --> Mg^+2 + 2e-
cathode side: Sb +2e- --> Sb^-2
full rxn comes from adding the halfs.

Mg + Sb --> Mg^+2 + Sb^-2
from what I read on the flyer, the Sb would be tapped into the grid to delivery power to the consumers, and the juice would retuning through the Mg.
