Seminar 4/1/2015 - Martin Bazant, Massachusetts Institute of Technology: Some New Concepts in Batteries
Abstract: This talk will introduce some mathematical models and battery designs that push the boundaries of electrochemical engineering:(1) For Li-ion batteries, the empirical Butler-Volmer equation is replaced by the predictive Marcus theory of charge transfer, and a new theory is proposed for driven phase transformations in nanoparticles and porous electrodes.(2) For flow batteries, new membraneless designs with bromine chemistries are developed that drastically lower large-scale energy storage costs (H2-Br2) or provide flexible vehicular or naval power (Li-Br2-O2).(3) For metal batteries, new charged separators can suppress dendrites by forming stable deionization shock waves -- a concept that can also be exploited for water purification by “shock electrodialysis”.

All seminars are held on Wednesdays from 12:00 noon-1:00 p.m. in the Bowen Hall Auditorium Room 222. A light lunch is provided at 11:30 a.m. in the Bowen Hall Atrium immediately prior to the seminar.
