ScienceX on Instagram: "Electrically Charged Rocks? The Hidden Power of Lithium in Geology As geologists often look at rocks for what they tell them about Earth’s history — but some minerals do more than talk. Some… generate power. One of the most fascinating examples? Lithium-bearing minerals like lepidolite and spodumene, known for their piezoelectric and pyroelectric properties. When certain rocks containing lithium-rich minerals are subjected to mechanical pressure, friction, or temperature
