This work is about following the tracks of a game-changing mineral. Batteries are catalysts of massive changes in our time, both industrial and social. The boom of battery-driven cars, phones and robots is causing the market’s core component lithium to soar, creating a modern-day gold rush with geo-strategic consequences. The story follows the value chain of this rare mineral, from investment and prospecting in the US, to the mining in Bolivia, production of batteries and cars in China, and to the small oil state Norway, leading the way to electrify all of its transportation means – cars, buses, planes and boats. This is the story of how lithium is changing societies and just possibly might have a role in saving our planet. But at a high cost.
