Interactive Breakfast Breakout Discussion Groups

Join your colleagues and fellow delegates over breakfast for a focused, informal discussion moderated by a member of our speaking faculty. A small group format allows participants to meet potential collaborators, share examples from their own work, vet ideas with peers, and be part of a group problem-solving endeavor.

TABLE 1: Hydrogen vs Electric Infrastructure

Moderator: Robert Bienenfeld, AVP, Environment & Energy Strategy, American Honda Motor Co., Inc.

  • How do the energy cost per mile compare?
  • What are the infrastructure costs per vehicle?
  • What are the prospects for the future?

TABLE 2: 12V Electrical Architectures with Advanced Energy Storage

TABLE 4: Chinese Material Suppliers, Cost, and Quality Status (Including Japan and Korea)  

Moderator: Sachiya Inagaki, Seoul Branch Office General Manager, Yano Research Institute, Ltd.

  • How those Asian manufactures see the market in the U.S. and Europe and vice versa
  • How to deal with those Asian manufactures, focusing on business style
  • Will xEV market really raise supply shortage in materials?

TABLE 5: Lithium-Ion Battery Safety: Prediction, Prevention & Management

Moderator: Brian Barnett, Vice President, TIAX LLC

  • Are abuse tests such as nail penetration, hot box, overcharge, crush a realistic indication of what happens in the field?
  • Can short detection, coupled with intervention strategies, provide adequate and confident levels of safety?  What is an adequate level of safety?
  • Is it better to focus on prevention of a first cell reaching thermal runaway, or better to focus on prevention of cascading?
  • What needs to be done to make air shipment of lithium-ion truly safe?
  • Will 400 Wh per kg batteries employing solid state electrolytes be safer than today's lithium-ion?

TABLE 6: Cell Manufacturing

Moderator: Raf Goossens, Ph.D., CEO, Global Corporate Management, PEC

  • What are the key challenges for manufacturing large format cells?
  • How can we achieve the large volumes that will be needed to fulfill the expected future market demands?
  • What simplifications can be introduced during manufacturing?
  • How can we progress with reducing the current cell manufacturing cost?
  • What are the safety risks during manufacturing and how can we handle these?

TABLE 7: Silicon Anodes and Cells

Moderator: Benjamin Park, Ph.D., Founder & CTO, Enevate

  • What is the best expected cycle life with Si anode today? What are the paths to improve?
  • Besides energy density, does Si anodes have other intrinsic advantage vs. graphite anodes?
  • What are the manufacturing challenges?
  • How does safety of Si based cells compare to graphite based cells?
  • How to control or prevent volume expansion?

TABLE 8: Lessons Learned from Recent Battery Safety Events

Moderator: Shmuel De-Leon, CEO, Shmuel De-Leon Energy, Ltd.

  • We will discuss the event and its causes
  • What are the lessons we should learn and what steps can be taken to prevent these events
  • How has this event affected the battery industry?

TABLE 9: Conductive Additives for High Rate LIB Performance

Moderator: Rob Privette, Vice President, Energy Markets, XG Sciences

  • What are the key challenges for improved electrode rate performance in LIB cells?
  • What are the material needs for satisfying increasing power and energy demands?
  • How do manufacturing processes impact material requirements?
  • Are the demands for increasing power compatible with the need for reduced cell cost?

TABLE 10: Recent Advancements in Automotive Lead Batteries and the Commercial Outlook

Moderators: Boris Monahov, Ph.D., Program Manager, Advanced Lead-Acid Battery Consortium (ALABC) - a program of the International Lead Association (ILA)

Alistair Davidson, Ph.D., Director-Products and Sustainability, International Lead Association

  • Overview of recently analyzed lead battery performance data for 12V start-stop and micro-hybrid applications and 48 V mild-hybrid applications
  • Future battery science developments in line with the new 1618 ALABC Program and their potential application for future vehicles
  • How do the energy cost per mile compare?
