> There's no efficient / cost-effective way to extract lithium from spent batteries for reuse in new batteries. We might in the future but it would require some scientific advances + expensive commercialization to scale up. It's already 95% efficient. No fundamental scientific advances are needed. It's already being scaled commercially. One example: https://li-cycle.com/ https://li-cycle.com/
