How does this work ?
with magnesium (Mg) and antimony (Sb) electrodes
and have since moved to a chemistry with a higher voltage and lower cost. In a charged state, there is
potential energy between the top metal layer and the bottom metal layer which creates a cell voltage.
To discharge the battery, the cell voltage drives electrons from the Mg electrode, delivering power to
the external load (e.g., light bulb), and the electrons return back into the Sb electrode.Internally, this
causes Mg ions to pass through the salt and alloy with Sb, forming a Mg-Sb alloy.
