This is a Canadian company, neat.
For the mobile ion in a battery, lithium is the best. The old lead-acid batteries used hydrogen, and there might be a use for chlorine. But, if we are going into a lithium economy, due to the 'overwhelming belief' in climate extrapolations, then China owns the world.
If we embraced physics and the Scientific Method in Canada, then we could start a 'Get the heck out of lithium' movement, but we're all full with movements these days.
Then add in rare earths for solar cells and such, and China is king again. Oh well, Europe is a dog to Pootine, and we love China, what did they ever do to us?
ps. Rah, rah China!
