Welcome to the era of supercharged lithium-ion batteries

Gene Berdichevsky believes in batteries. As employee number seven at Tesla, he helmed the team that designed the lithium-ion battery pack for the company’s first car, the Roadster, which convinced the world to take electric vehicles seriously. A decade later, EVs can hold their own against your average gas guzzler, but there’s still a large trade-off between the shelf life of their batteries and the amount of energy packed into them. If we want to totally electrify our roads, Berdichevsky realized, it would require a fundamentally different approach.

Per“Manufacturing energy analysis of lithium ion battery pack for electric vehicles”(Chris Yuan et al), it takes about 24000 kWh of energy to make a 24 kWh battery, including energy to mine the materials and transport etc. Not all of that is electrical energy.
