The Birth of the Li-ion Secondary Battery - A Problem Child?
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 University

One 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.


Solid State Energy Storage: Game-Changing Technology for the 21st Century
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.

Towards Online Assessment of Battery State of Health and State of Safety
Rachid Yazami, Ph.D., Professor, School of Materials Science & Engineering; Director, Battery Programs, Energy Research Institute, Nanyang Technological University, Singapore

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

From Gallium Nitride to Silicon Carbide; Power Management Advancements Enabling Battery Market Growth
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.
