Autonomous Discovery of Battery Electrolytes with Robotic Experimentation and Machine Learning
Presenter: Venkat Viswanathan, Faculty Fellow at the Wilson E. Scott Institute for Energy Innovation and Associate Professor of Mechanical Engineering at Carnegie Mellon University
Date: August 12, 2020
Time: 1-2pm ET
“Innovations in batteries take years to formulate and commercialize, requiring extensive experimentation during the design and optimization phases. We approached the design and selection of a battery electrolyte through a black-box optimization algorithm directly integrated into a robotic test-stand. We report here the discovery of a novel battery electrolyte by this experiment completely guided by the machine-learning software without human intervention. Motivated by the recent trend toward super-concentrated aqueous electrolytes for high-performance batteries, we utilize Dragonfly—a Bayesian machine-learning software package—to search mixtures of commonly used lithium and sodium salts for super-concentrated aqueous electrolytes with wide electrochemical stability windows.”
