BREAKOUT DISCUSSIONS

8:30 – 9:30 | Thursday, 2 February


Continental Breakfast Roundtable Discussions
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: Battery R&D in Europe
Alfons Westgeest, Executive Director, Association of European Automotive and Industrial Battery Manufacturers

  • Why is R&D in Europe important?
  • What is the roadmap of current main battery technology families?
  • How will Europe develop the value chain in battery manufacturing?
  • What are the drivers for co-existence of various technologies?

TABLE 2: How Much Life is Left in Lead-Acid?
Christian Rosenkranz, Ph.D., Vice President, Engineering & Product Development EMEA, Johnson Controls Autobatterien GmbH

  • How far can we push the Lead-Acid technology in it’s critical parameters: dynamic charge acceptance (over life) and cycle life performance?
  • When is the tipping point to be reached in modern 14V advanced start-stop vehicles which will require a different level of performance?
  • How to tailor the next generation of AGM to the increasing requirements?
  • Do present cycle life tests represent the future requirements in vehicle application or which would be the most important drivers to focus on?

TABLE 3: Lessons Learned from the Samsung Galaxy Note7 Battery Safety Events
Shmuel De-Leon, CEO, Shmuel De-Leon Energy, Ltd.

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

TABLE 4: Cell Manufacturing
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 be progress with reducing the current cell manufacturing cost?
  • What are the safety risks during manufacturing and how can we handle these?

TABLE 5: Silicon Anodes
Dee Strand, Ph.D., CSO, Wildcat Discovery Technologies

  • Silicon alternatives to carbon anodes in lithium-ion batteries
  • Nanoscale Si exhibit high charge storage capacity with stable cycling
  • Binder and conductive additives underlie good Si anode performance
  • Stabilizing solid electrolyte interphase layer formation
  • Si anodes have exhibited capacities much greater than other materials

TABLE 6: Addressing Electrolyte Challenges for Solid-State Batteries
Josh Buettner-Garrett, Ph.D., CTO, Solid Power

  • What remaining challenges do we have with electrolytes?
  • How can a solid-state battery improve safety?
  • What will be the path to commercialization for solid state-batteries?

TABLE 7: Advances in Battery Modeling
Bob Spotnitz, Ph.D., Battery Design LLC

  • Standards on specifications for materials and cells that better define their characteristics
  • Standards on testing methods for cells and modules that accounts for boundary conditions
  • Value of standard circuit model complete with procedures for obtaining parameters similar to USABC circuit model
  • What is best approach for estimating battery life?

TABLE 8: Battery Costing and Cost Reduction
Wenzel Prochazka, Ph.D., AVL List GmbH

  • Battery Safety Requirements (cost & weight): Exaggerated or based on real scenarios?
  • Housing technologies: Where do we see highest future cost reduction potential (Casted, plastics, extrusion/welded, sheet metal)?
  • Batteries as structural vehicle parts: what is the offset value?
  • Cost analysis methodology: What is the participant’s experience with early cost engineering within the development process?

TABLE 9: PHEV, EREV, or BEV: Pros and Cons
Roland Matthe, Adam Opel AG

  • Differences in batteries for PHEV/EREV/BEV
  • Effect of changing boundary conditions (incentives vary from region to region), cost come down only with scale
  • Challenges of designing to fast changing regulatory settings
  • Trade-off vehicle integration requirements and Battery optimization parameters

TABLE 10: Failure Propagation Testing of Battery Packs
Daniel Doughty, Ph.D., President, Battery Safety Consulting, Inc.

  • What is the best method of initiating the thermal runaway in the “trigger cell”?
  • What is the preferred location of the “trigger cell”?
  • Do propagation tests of battery packs made from large cells (over 20 Ah) need to have different procedures than propagation tests of battery packs made of smaller cells?
  • Does propagation to all adjacent cells need to be avoided, or is propagation to a “limited number of cells” sufficient?

TABLE 11: Energy Storage and Charging Standardization
Kevin R. Konecky, Energy Storage Systems Consultant, Total Battery Consulting

  • Discuss possibilities of standardizing cells, modules, and packs
  • Discuss difficulties in standardizing cells and modules in low-profile floor-pan packs vs higher-profile pack designs
  • Discuss standardization of regular and fast charging
