1:45 Past, Present and Future of Lithium-Ion Batteries. Can New Technologies Open Up New Horizons?

Yoshio_NishiYoshio Nishi, PhD, Executive Alumni, Sony Corporation

Mr. Yoshio Nishi is retired senior vice president and chief technology officer of the Sony Corporation. He graduated in 1966 from the Faculty of Applied Chemistry of the Department of Technology at Keio University in Tokyo and immediately joined Sony, where he rose through the ranks to become corporate research fellow, vice president, and president of the company’s materials laboratories. In 1991 his team succeeded in the commercialization of the first lithium-ion secondary batteries (LIB). In 1994 he received technical awards from the Electrochemical Societies of both Japan and the United States in recognition of his contributions to LIB technology. In 2014, Dr. Nishi was awarded the Draper Prize by the National Academy of Engineering for pioneering and leading the groundwork for today’s lithium-ion battery. Since the early 1990s, LIBs were introduced into various mobile devices and we were reasonably confident that our customers would be satisfied with their performance. Shortly afterwards, however, we noticed that there were some discrepancies between the performance we offered and that expected by our customers. Dr. Nishi will discuss here what LIB users really require from secondary batteries.

2:05 Global Electrification and LG Chem

Denise GrayDenise Gray, CEO, LG Chem Power

Denise Gray is President/CEO of LG Chem Power Inc. (LGCPI), the North American subsidiary of lithium-ion battery maker, LG Chem (LGC), Korea. In this position, she has overall responsibility for the strategic direction, engineering, and business development activities for the North American market. The majority of her professional career, nearly 30 years, was spent at General Motors in the USA. Director of Battery Systems Engineering, Director of Transmission Controls Engineering, Director of Powertrain Controller Engineering, Director of Powertrain Software Engineering, and development of powertrain and vehicle electrical systems were her core engineering responsibilities. A review of the current global trends in vehicle electrification and automotive battery technologies will be presented. This will be carried out highlighting LG Chem’s participation in the various segments from materials, cell and cost points of view.

2:25 Addressing Key Battery Issues from a Thermodynamics Perspective

Rachid_YazamiRachid Yazami, PhD, School of Materials Science & Engineering, Program Director, Energy Storage, Energy Research Institute, Nanyang Technological University, Singapore

Rachid Yazami is a French Morrocan scientist best known for his research on lithium-ion batteries and on fluoride-ion batteries. He is the inventor of the graphite anode (negative pole) of lithium-ion batteries. In 2014 Rachid Yazami, John Goodenough, Yoshio Nishi and Akira Yoshino were awarded the Draper Prize by the National Academy of Engineering for pioneering and leading the groundwork for today’s lithium-ion battery. In this presentation, we will show how online thermodynamics data collection and processing addresses the SOC and SOH determination. We found a universal rule, which applies to all LIB tested at any SOH (ageing), that is the SOC is a linear function of entropy and enthalpy. Linearity coefficients are LIB chemistry and SOH dependent. Therefore, the thermodynamics assessment method teaches on the type of cathode material and on the degree of anode and cathode degradation as the battery ages.

4:40 Quality Philosophy in the Manufacture of Lithium Ion Batteries

Bruce Miller, Technology Strategist, Dell

The manufacturing processes employed in the creation of lithium ion cells are quite convoluted and intricate. To ship a good consistent product, the process design and control methodology employed must be quite rigorous. Attention to detail is important from end to end. In actual practice, two manufacturing processes may appear to be equivalent, but the implementation approach can significantly affect the output of the process. A few real world examples will be used to illustrate the points.

11:20 Cell Internal Shorts as Next Frontier of Battery Safety: Types, Prevention and Detection inside Battery Pack

Yevgen_BarsukovYevgen Barsukov, Head, Algorithm Development, Battery Management Systems, Texas Instruments

Present battery packs have sophisticated protection against external device faults, leaving cell internal short as the last frontier that needs to be addressed. Depending on the type of internal short, it can be either prevented by improved cell-state aware charging controls such as MaxLife charging, or in some cases detected in early stages, giving the manufacturer exact knowledge of time and type of failure. This would allow the manufacturer to take quick corrective action and avoid potential costly recalls.

3:05 Healing of Lithium Metal Dendrites in Electrochemical Energy Storage Devices

Lu Li, Research Assistant, Nikhil A. Koratkar Group, Department of Mechanical, Aerospace, and Nuclear Engineering, Rensselaer Polytechnic Institute

I will describe how self-heating (Joule heating) can be used to anneal and heal lithium metal dendrites in lithium-sulfur batteries. Operation of the battery at high operating current densities (i.e. high charge-discharge rates) will be used to heat the lithium dendrites. Above a critical activation temperature, surface diffusion and migration of Li atoms is triggered resulting in a morphology change of the dendrites into a smooth film-like morphology, which eliminates the risk of dentritic shorting of the electrochemical cell.
