8:45 Impact of the xEV Market Growth on Lithium-Ion Batteries and Raw Materials Supply 2019 –2030

Christophe Pillot, PhD, Director, Avicenne Energy

Today less than 1% of the automotive market is Electric Vehicle. With this very small market share, xEV already consume more than 60% of the total Li-ion battery production, more than 40% of the Cobalt production and more than 50% of the Lithium production. With conservative xEV forecasts (5 Million EV sold per year in 2025), the impact on the Lithium ion battery market and supply chain will be huge.

9:05 The xEV Revolution – Will Customers Get on Board and the Battery Industry Behind It?

Stephanie Schenk, Senior Research Analyst, Advanced Industries - Automotive & Assembly, McKinsey & Co.

Markus Wilthaner, Associate Partner, McKinsey & Co.

Electrification is the most prominent trend of the four "ACES" trends that will revolutionize mobility. Driven by regulation, technology and consumer demand, EV sales have kept surging throughout 2018. Motivated by stringent CO2 and emission targets, the industry has moved from a wait-and-see mode to one focused on “doing”. At the same time, customer familiarity and interest in EVs are increasing. All this is driving EV uptake in the coming years and, as a result, the demand for LiB. The battery remains the key EV challenge for OEMs, customers and the society, therefore driving technological advancements and a ramp-up of battery production capacity. In this talk, we will share insights on xEV markets, the customer perspective and the development of (European) cell supply and demand.

9:35 Chinese xEV Market Expansion: Opportunity or Challenge?

11:10 xEV Market Expansion

Menahem Anderman, PhD, President, Total Battery Consulting, Inc.

This presentation will assess the expansion of the xEV market. It will show that while xEV market expansion is now unstoppable, the pace of growth for each of the of xEV architectures is tied to i) regional-government regulations, ii) battery and vehicle technology and cost development, and iii) consumer eagerness. Predicting the growth of both the xEV market and the batteries that will power the vehicles is thus tied to anticipating development in the above three areas. We will attempt to provide some likely scenarios and estimate the resulting battery and xEV markets.

11:35 Price Elasticity of Supply for Cathode Materials in a Fast-Growing Vehicle Electrification Scenario

Kurt Vandeputte, Vice President, Rechargeable Battery Materials Business Unit, Umicore

Vehicle electrification is growing at a healthy pace which translates into unseen growth rates of cell making. Consequently, demand for the different cathode materials is high which in turn leads to imbalances on the market for key raw materials like lithium, nickel and cobalt. For all these critical materials the emerging battery industry will be the dominant downstream use. Since these materials contribute significantly to the total $/KWh-cost of the battery, it is critical to have good insights in the fundamental characteristics of these respective markets. In this presentation current and future supply/demand balances will be discussed, price elasticity of supply scenarios and its consequences towards battery cost curves will be highlighted.

14:00 The Influence of the Entropic Effect on Battery Performance

Andreas Jossen, PhD, Professor, Electrical Engineering and Information Technology, Technical University Munich

The reaction entropy while charging and while discharging within lithium-ion batteries depends on the state of charge and it has a significant influence on the battery characteristic. Next to the strong influence on the heat generation, it directly influences the open circuit voltage. These effects can be used to measure the entropic coefficient, to do SOH diagnostics, but also result in inhomogeneities. The presentation will show how to measure the entropic coefficient, how it can be used for SOH determination and possible effects within cylindrical cells that result in a reversible but also in irreversible aging.

14:20 Diagnosis of Li-Ion Battery health with Nonlinear Frequency Response Analysis

Ulrike Krewer, PhD, Professor, Technical University Braunschweig

This talk demonstrates that nonlinear frequency response analysis (NFRA) is a highly potent method for analyzing the state of health of Li-ion batteries. The nonlinear dynamic method is sensitive to changes at electrode surfaces. After introducing typical spectra and their interpretation, the potential of the method for monitoring and discriminating between aging processes in cells is demonstrated in the example of cycling-aged vs. Li plated cells: While in both cases the recorded EIS look qualitatively similar, NFRA shows distinct qualitative features.

15:55 Transport Regulations for Lithium Ion Batteries and the Impact on the Automotive Market

David Brennan, Assistant Director, Cargo Safety & Standards, International Air Transport Association

Transport regulators continue to look at the potential hazards, and risks, posed by the transport of lithium batteries. Air transport regulators, through ICAO continue work on the development of a standard that can be used to test batteries as prepared for air transport to validate that the batteries do not pose an unacceptable risk. In parallel the United Nations Subcommittee of Experts on the Transport of Dangerous Goods is considering revisions to lithium battery classification to develop a hazard-based approach to the classification of lithium batteries, and by extension to the transport conditions. This presentation will look at potential developments to revise the transport regulations applicable to lithium ion batteries across all modes of transport with then a focus on air transport.

16:15 EV Wireless Charging Drives the Future of Mobility

Peter Wambsganss, Director, Business Development AIMM - Europe Region, WiTricity Corporation

WiTricity is focused on improving the EV ownership experience—no more cables, and no worry about charging. We also recognize that the future of mobility is electrified, autonomous and shared, and wireless charging is an essential enabler for fleets of robotaxis where there is no driver to plug in. EV wireless charging is an enabler for broad consumer EV adoption, lowering our carbon footprint, and can act as a catalyst for Vehicle to Grid which is important for expanding renewable energy sources. We believe that V2G will be a game changer for EVs as it transforms cars into energy management systems, and not just forms of transportation.
