Circu Li-ion cofounder and CEO Antoine Welter says his startup’s upcycling machine can diagnose batteries in seconds. “We know exactly which cell can be reused and which one can’t,” he told TechCrunch on Monday.

Circu Li-ion is in the business of saving usable battery cells from shredders. The German startup’s machine identifies batteries by their appearance, via AI and a growing battery library; it separates cells from other materials, such as plastic housing and PVC boards; and it determines the cells’ states of heath.
