Metllic Magnesium is not a good idea for batteries, just like lithium (metallic-lithium batteries are also known as LiPo batteries): in case of dendrites formation in the electrolyte, a short circuit happens and all burns up.
They solved the issue using li-ion electrodes rather tahn metallic-ion electrodes

Which gravimetric density (Wh/kg) can be reached?

Nicholas, To the best of my understanding, Magnesium is a flammable metal. I remember that Porsche used Magnesium in the floor of their cars and if there was a short circuit, it would catch fire and could not be extinguished by the fire department. I witnessed this at an auto auction in the 1990’s, the car burned to the ground with the fire department frantically trying to put it out.
Is there any data about the flammability of the Magnesium batteries?

You can get some idea from test data on the Leaf. Look at the Range section…

You might try looking for the EPA L4 test data, it might be on line.

I have repeatedly asked the question of what the air conditioning used on a south Florida summer day does to range and the industry does not answer.

Uh….huh? 200 miles per charge? There aren’t any cars that get over about 90 miles per charge, most are under 60…..except the Tesla and a couple of other expensive ones….tesla relies on it’s structure as a battery….I have no idea where those figures came from….if they were true, we woulodn’t have a world with range anxiety.
