" Electrochemical Energy Conversion and Storage for A Sustainable Energy
Future"

Yang Shao-Horn

Professor, MIT Mechanical Engineering
Wednesday December 13, 5:00-6:00pm
 E40-496 <http://whereis.mit.edu/map-jpg?selection=E40&Buildings=go> 

 

Abstract

The depletion of fossil fuels and the increasing environmental concerns
demands economical, efficient energy systems.  Electrochemical conversion
and storage directly convert chemical energy to direct-current electrical
energy via electrochemical reactions, which has demonstrated high efficiency
and great promise as key components in hybrid energy systems for
transportation and stationary needs. However, the practical energy and power
density and the cost of electrochemical systems such as lithium rechargeable
batteries and fuel cells limit their market penetration and competitiveness
relative to conventional technologies. These performance characteristics
strongly depend on the thermodynamics and kinetics of reactions at the
electrode-electrolyte interface and bulk electrodes, and mass and electron
transport to the interface. We will focus on electrode kinetics (charge
transfer across the interface), transport processes and material stability,
and will discuss their effects on the efficiency, energy and power density
and durability of lithium rechargeable batteries, proton exchange membrane
and solid oxide fuel cells.

 

Biography

Yang Shao-Horn is Assistant Professor in Mechanical Engineering at MIT. Her
research in the Electrochemical Energy Laboratory probes fundamental
processes/phenomena in materials and at interface to understand
molecular/atomic processes of electrochemical oxygen reduction and lithium
storage, reveal materials degradation mechanisms and develop new materials.
She obtained her Ph.D. in Metallurgical and Materials Engineering from
Michigan Tech. in 1998 and then worked as a staff scientist at Eveready
Battery Company. Select honors include Dupont Young Faculty Award 2006; Air
Products Faculty Excellence Award 2006; MIT Presidential Energy Research
Council 2005-2006; the 2003 Office of Naval Research Young Investigator
Award; NSF International Research Fellow Award 2000-2002; Norman Hackerman
Young Author Award of 1998 from the Electrochemical Society.
