We need to electrify much of the global economy in order to hit net-zero emissions by 2050. That means installing a lot of batteries in our cars, buildings, and across the grid to balance vast amounts of wind and solar.

The supply chain behind all those batteries could be worth nearly half a trillion dollars by 2030. Whoever controls that supply chain has enormous power – figuratively and literally. 

In this episode, we explore the stakes of the battery-based transition. We’ll open up a lithium-ion battery, investigate what's inside it, and ask whether critical minerals will look anything like oil.

This is the first episode of a five-part series exploring the lithium-ion battery supply chain. In the next four episodes, we’ll cover each step of the process, from mining to recycling.
