Watch this 53-minute conference talk where Martin Bazant from MIT presents a groundbreaking unified quantum theory that bridges the century-old Butler-Volmer equation with modern Marcus theory for electrochemical reaction kinetics. Explore how the coupled ion-electron transfer (CIET) framework resolves longstanding debates between electron transfer and ion transfer mechanisms by providing a single rate formula that interpolates between Marcus-like and Butler-Volmer-like kinetics depending on whether electron or ion transfer is rate-limiting. Discover the theory's practical applications in lithium-ion and lithium-air battery systems, electrocatalysis, and hydrogen evolution reactions, with specific examples showing how metal dependence affects reaction rates. Learn how this theoretical framework connects quantum chemistry calculations with electrochemical engineering applications, enabling prediction of electrochemical reaction rates from first-principles quantum simulations. Gain insights into recent research developments including lithium-ion intercalation mechanisms, morphology control in Li-O2 batteries, and computational studies of charge-transfer kinetics at electrode interfaces, all unified under this comprehensive theoretical approach that provides the missing microscopic foundation for electrochemical kinetics.
