Intro:

This is lithium.. Pretty soon, we’re going to need a lot of it.. Lithium is a useful metal.. It spends its entire existence trying to get rid of its one outer electron but, crucially,
this reaction can be both controlled and reversed.. That means, properly configured, the metal can discharge energy when needed, take in
more energy, and then discharge that energy.. Essentially, it can act as a battery.. It’s only been a few decades since lithium-ion batteries reached commercial feasibility but,
in that time, they have become the power source of choice for portable electronics thanks
to their perfect blend of safety and lightness.. However, the latest major tech boom, the latest infatuation of Silicon Valley and Wall Street
alike, is centered around the largest consumer electronics product to date: electric vehicles.
And pretty soon, we’re going to need a lot of them.
The UK, for example, has committed to banning internal combustion car sales by 2030.
To replace its 31.5 million vehicles, about 236,000 metric tons of lithium carbonate are
needed.. To produce 236,000 metric tons of lithium carbonate, every lithium mine in the world
would have to devote its output to this one use for nine months, and there are a whole
lot more countries, a whole lot more lithium applications, and a whole lot more growth
