I was at an event today where Al Gore spoke positively about LiON battery as energy storage. I was a bit surprised .. is this sustainable tech?

There are two issues that come to mind .. do we have enough materials to make more and more LiON batteries (grid level storage) and are these things recyclable/not going to mess up the Earth?

Ultimately, yes. There are a variety of lithium battery technologies, so it's important to recognize that there are differences, and that the state-of-the-art does change with some frequency. But, if nothing else, the metal inputs to battery production can be smelted and recovered, and Lithium is plentiful. "Good" recycling of batteries would involve recovering the electrode materials directly and easily 'refreshing' them. This would make batteries very sustainable. Work on developing this process for various chemistries is ongoing, but not yet ready. Research and development of recycling-friendly chemistries and production is just beginning. https://cen.acs.org/materials/energy-storage/time-serious-recycling-lithium/97/i28 https://cen.acs.org/materials/energy-storage/time-serious-re... The batteries themselves will be getting much more durable. A JES article was recently published that made quite a few headlines as a 'million mile' car battery, but it's not hype. http://jes.ecsdl.org/content/166/13/A3031 http://jes.ecsdl.org/content/166/13/A3031 This is extant technology (indeed, at least 3 years old) that's proving to be exceptionally durable. This gives batteries at least two decades of nearly-full capacity, with the potential to last much longer with useful capacity. We're not there yet, but there's no physical or chemical reason that Lithium battery technology can't be sustainable.
