What's the Tipping Point?

Imagine a future where all the lithium we need has already been extracted from the ground and is endlessly recycled. Or where the batteries we use to store renewable energy are made from abundantly available materials — like salt.

This episode, we visit a lab where a couple of brilliant scientists are trying to build the batteries of the future. And we drop in on a company that’s extending the life cycle of lithium through something called “urban mining.”
