PLENARY KEYNOTE SESSION
Yoshio Nishi, Ph.D., Executive Alumni, Sony Corporation
The first commercial Li-ion secondary battery was introduced in 1991 by Sony Corporation. We met many difficulties in developing the Li-ion secondary battery and I would like to describe how we overcame them. We believed that the resulting newborn had sufficient characteristics. Our customers, however, were not satisfied with them and severe comments were made on them. The key factors that they claimed will be presented here, and it will be emphasized that it is essential to appreciate what characteristics are required by the customer.
4.7V Li-ion Cells: Nonsense or Possibility
Jeff Dahn, Ph.D., Professor, Department of Chemistry, Dalhousie UniversityOne way to improve the energy density of Li-ion cells is to use high voltage positive electrode materials like LiNi0.5Mn1.5O4 [LNMO] or simply increase the upper cut off potential when positive electrodes like Li[NixMnxCo1-2x]O2 [NMC] are used. This sounds simple, but there are numerous problems to overcome before high voltage Li-ion cells are a reality. In this talk, I discuss the problems and describe partial solutions we have developed. These encouraging results provide hope that high voltage Li-ion cells can be a reality one day. Time will tell.
Ann Marie Sastry, Ph.D., Chief Executive Officer & Founder, Sakti3
Recently, Sakti3, a University spinout founded by researchers and engineers with decades of experience in battery research and thin film and other manufacturing, developed an approach for production of cells which offers all of the benefits of the theoretically highest energy density materials available. These massively replicable, cheap and reliable production methods enable cell manufacturing in a single, unified line and produce product that is ready to ship.

Lithium ion batteries (LIB) provide excellent performances in terms of energy density, power density and cycle life. After remarkable success in mobile electronics application, the rapidly growing market is in electro-mobility (EM) and in energy storage ES). We have developed a universal technology based on thermodynamics data collection and analysis, which enables to monitor battery SOH and SOS

It also includes highlights of many significant research breakthroughs resulting from VTO-funded R&D. A discussion of electric drive vehicle technology performance targets, gaps, and future research directions is also included.
Dave Heacock, Ph.D., Senior Vice President and General Manager, Silicon Valley Analog Business, Texas Instruments
Wide bandgap devices and advance semiconductor materials are becoming more mainstream. With this shift, traditional power management topologies are giving way to new capabilities and architectures within power management systems. By combining these architectures with the expanding capabilities of rechargeable batteries, new growth markets are appearing. This paper looks at the relationship between these technologies and examines some of the possible growth areas for batteries and power management devices.
Vehicle Electrification Market Trends and Battery Technology Status Update
Prabhakar Patil, Ph.D., Chief Executive Officer, LG Chem Power, Inc., KoreaThis presentation will provide an overview of the automotive market and specifically focusing on the BEV, PHEV/EREV, 48V and 12V systems. Key highlights include: 200 mile vehicle for <$35K for BEVs; 30+ mile electric range for PHEV/EREV; Chinese CO2 regulation achievement for 48V systems at 95 g/km; Cost and compatibility for 12V systems.
