Look out for lithium, the next boom metal

THE age of electrification across the transportation sector, the solar panel revolution, and Tesla's battery gigafactory are igniting a battle for the cheapest battery. That will transform lithium into a boom-time mineral and the hottest commodity on the energy investor's radar. It has been easy to take lithium for granted. This wonder mineral is the backbone of our everyday lives, popping up in everything from the glass in our windows to our mountains of electronics.

And while investors have long appreciated the steady rise in demand for this preferred mineral, the number of new applications continues to multiply. Smart phones, tablets, laptops, and other consumer electronics demand more lithium. But the largest driver for future lithium use will be in electric vehicles and home batteries for solar panels. That has lithium on the verge of a boom for which supply can no longer be taken for granted.

Not since the shale boom have we seen a market transformation of such significance. Lithium has long been used for a variety of mundane purposes, and while the variety is spectacular - with applications in everything from glass, ceramics and greases to a lineup of industrial processes - it has flown under the radar for most investors.
