Short Course #5 Materials for Li-Ion Batteries: Structures, Performance, and Durability
Quinn C. Horn and Yue Qi, Instructors
Please visit the Montreal meeting page for registration information. Early-Bird Registration rates are in effect until April 1, 2011. See a list of all Short courses offered at the Montreal meeting.
Designing high energy, high power, long lasting, less expensive and safer rechargeable lithium batteries requires new developments in materials, which requires fundamental understanding of the many chemical, physical, and mechanical processes that determine the materials’ performance and durability.
The aim of this course is to provide a foundation for understanding the structures, chemistry, and solid-state physics of the electrodes and electrolyte materials for rechargeable lithium batteries. Materials evolution during cell operation and failure mechanisms of these materials and their consequences on the cell behavior will be illustrated with real examples. Various computational tools, from first principle calculations to Newman’s battery cell level of modeling, will be introduced to provide a multi-scale pathway to connect material design with battery design. Finally, we will introduce the new challenges that transportation applications face and the areas where material breakthroughs are required.
This course will cover the following:
a general introduction into lithium and lithium ion batteries;
materials inside Li-ion batteries, including: anodes and solid-electrolyte-interface (SEI) considerations, electrolytes, cathodes and interface considerations, and nano materials and nanostructured electrode design (pros and cons);
degradation mechanisms (chemical and structural);
multi-scale simulations for electrode materials; and
special requirements for transportation applications.
About the Instructors
Quinn C. Horn is a Senior Managing Engineer in Exponent’s Mechanics and Materials practice. Dr. Horn consults in the areas of metallurgy and electrochemistry and frequently addresses issues related to corrosion analysis, battery manufacturing, and battery science. He has extensive experience developing characterization techniques for understanding discharge reactions and degradation mechanisms in a wide range of battery systems including lithium-ion, lithium-primary, nickel-metal hydride, nickel cadmium, lead-acid, and alkaline primary cells. Prior to joining Exponent, Dr. Horn held positions as a Principal Scientist at Physical Sciences Inc. (PSI), and as a Staff Technology Engineer at Energizer/Eveready Battery Company. At PSI, Dr. Horn designed, developed, and tested high-energy and high-power electrodes for lithium-ion batteries. At Energizer, Dr. Horn was responsible for the Microscopy and Materials Group, where he conducted failure analysis studies to solve problems related to battery failures and battery manufacturing issues. Dr. Horn is a Research Affiliate at the Massachusetts Institute of Technology, where he collaborates with researchers in the Electrochemical Energy Laboratory on projects related to electric vehicles and new gas diffusion electrodes for metal-air batteries and fuel cells.
Yue Qi is a Staff Research Scientist working on multi-scale modeling on various materials at Chemical Sciences and Materials Systems Lab, General Motors R&D Center. She also holds an adjunct professorship in University of Windsor. She has published over 40 refereed articles. She has worked on interfaces and grain boundaries phenomena for light weight materials, proton exchange membranes for fuel cells and electrode materials failure for Li-ion batteries. For her past work, she received GM Campbell research awards for “Multi-scale Modeling of High-Temperature Deformation in Aluminum” (2009), “Fundamentals of Interfacial Tribology” (2009), and “Advances in Nano-Scale Plasticity” (2006). She was the co-recipient of 1999 Feynman Prize in Nanotechnology for Theoretical Work. Her current research interest is on integrating materials properties and microstructures into battery failure modeling. She had co-developed and lectured a 20 hours training course on “Basics of Electrochemical Cells and Li-Ion Batteries” for vehicle engineers in 2010.
