Lithium Batteries Here to Stay

We've been hearing about all sorts of new batteries but it seems in EVs it's lithium ion ones that will continue to dominate the landscape, says S&P Platts. Makes sense after so much investment in lithium.

Not really.  Lithium Ion has a slightly unstable chemistry, that under certain conditions will cause them to burst into flame. The older version of that chemistry is Lithium-Iron-Phosphate ["LIPO"], which is very stable and will endure all kinds of abuse.  That said, the Lipo batteries have this lower energy density, so you need more automotive real estate to hold the same amount of juice. I prefer the LIPO for the security of a stable and inert battery in there. 

You will see much better and cheaper chemistries coming along soon enough. The "investments" in Lithium will endure as there will remain a market for that, also in items such as cell phones, but for non-movable battery banks such as some competitive future version of the Powerwall, built by someone else, you are going to see new stuff.

My bet is on Aluminium-Ion and Aluminum-Sulfur, is cheaper, safer, less toxic, reciclable
