Martin Bazant - Unified quantum theory of electrochemical kinetics by coupled ion-electron transfer
Recorded 08 October 2025. Martin Bazant of the Massachusetts Institute of Technology presents "Unified quantum theory of electrochemical kinetics by coupled ion-electron transfer" at IPAM's Bridging Scales from Atomistic to Continuum in Electrochemical Systems Workshop.Abstract: The Butler-Volmer (BV) equation has become the standard model for electrochemical reaction kinetics, and yet a century later, it still lacks a clear microscopic basis. Butler (1936) first derived the BV equation from Gurney’s (1936) seminal “quantum theory of electrolysis”, which assumes electron transfer (ET) or “neutralization” is a fast step coupled to proton transfer. Marcus (1956) famously challenged this picture with his theory of ET coupled to solvent reorganization, rather than ion transfer. Here, we present a unified quantum theory of coupled ion-electron transfer (CIET), which leads to a simple rate formula that smoothly interpolates between Marcus-like and BV-like kinetics for rate-limiting electron- or ion-transfer, respectively.1 CIET theory provides a powerful link between quantum chemistry and electrochemical engineering, as illustrated by examples of reaction kinetics in Li-ion2 and Li-air3 batteries and electrocatalysis. The theory predicts the metal dependence of the hydrogen evolution reaction (HER) and provides a mathematical framework to predict electrochemical reaction rates from ab initio quantum simulations.4 1 M.
