Quartz crystal is the most widely used crystal when it comes to conducting electricity. It's resistance to wear and heat, added to its ability to regulate electricity, makes it a highly valuable substance for technology engineers . If you use different chemical and other ingredients we can produce a small crystal power cell 1.2V-1.5V

Magnesium core with a zinc nail
Copper case
Borax
Alum "Aluminium Sulfate Powder"
salt substitute
epsom salt

The problem we face is that after a few year of constant running, the degradation starts to destroy the power cell until pressure from the crystals forming inside spit the case.

How can we design the power cell to limit the pressure and improve the longevity of the crystal battery?
