New AI model can predict battery lifespan after only 50 cycles

University of Michigan researchers developed an AI system that can predict battery lifespan after just 50 charge cycles instead of the typical hundreds or thousands required, reducing testing time by 95 percent. The machine-learning model uses three specialized components that work together like lab researchers, analyzing early performance data through physics-based understanding to accurately forecast how long batteries will last across different formats from consumer electronics to electric vehicles.
