You will be familiar with lithium-ion batteries, the little knob-sized things that keep your wrist watch and other small electronic devices going for years. Slightly larger lithium batteries power cell phones, cameras, walkie-talkies, and other small portable devices. So, why should such batteries not be able to power your electric car as well?
Indeed, hybrid (electric/gasoline) and fully electric cars rely on lithium-type batteries at this time. To add to the electric (or should this read eclectic?) excitement, new battery technology breakthroughs are touted quite frequently.
Lithium Ores
Lithium is one of five naturally occurring alkali elements, with sodium and potassium the most common other ones. In contrast to sodium and potassium, lithium salts are not known to be vital components or nutrients for organisms. Also, though widespread, this element is relatively uncommon in the earth’s crust of rocks. There are few lithium ores and the high solubility of lithium salts in water means that they will precipitate or crystallize out last from any salt water lakes. But that’s exactly where much of our current lithium supply comes from, with Chile and China currently the major producers.
