2021 ME Battery Life Dectector
Prototype lithium-ion batteries built at the University of Michigan Battery Lab undergo diagnostic measurements inside an environmentally controlled chamber at 1015 Auto Lab on North Campus of the University of Michigan on October 15, 2021.
University of Michigan researchers identified an early-life diagnostic signal that predicts the impact of the formation protocols on battery life without needing cycle life testing. The technique can be deployed in battery manufacturing settings rapidly and at no additional cost. The newly discovered method can help battery manufacturers optimize their formation protocols and ensure that automotive-grade batteries can be both affordable and long-lasting.
