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 – fig
