As the energy capacity of new lithium-ion batteries (LIBs) hitting the marketplace increases, the risk of battery fires and explosions increases with it. While these fires or explosions are uncommon, the consequences can be devastating. Battery forensics and post-incident investigations are essential for identifying the root cause of a battery failure. Determining and understanding the underlying reasons for these events helps battery scientists create safer and more reliable batteries and enables regulatory agencies to develop safety standards and regulations. CET’s Inaugural Post-Incident Forensics & Investigations symposium convenes forensic scientists, regulatory authorities, cell manufacturers, fire safety investigators, and insurance companies to facilitate dynamic discussions on integrating LIBs safely into our mobile society.

Final Agenda

8:00 am Morning Coffee

8:30 Organizer’s Welcome

Mary Ann Brown, Executive Director, Conferences, Cambridge EnerTech

LITHIUM-ION SAFETY INVESTIGATIONS & CASE STUDIES

8:35 Chairperson’s Opening Remarks

Kevin Fok, Director, Operations, LG Chem

8:45 Experimental Investigation of Thermal Failure Propagation through Lithium-Ion Cell Arrays

Stoliarov_StanislavStanislav I. Stoliarov, PhD, Associate Professor, Department of Fire Protection Engineering, University of Maryland

To better understand the cascading failure process, a set of experiments was conducted in a small wind tunnel where 18650 form factor cells were arranged into a densely packed array and a failure of one cell was triggered using an electric heater. The dynamics of the propagation were quantified together with thermal energy release. In addition, the yields of oxygen, carbon monoxide, carbon dioxide, total hydrocarbons and hydrogen were measured; corresponding fire hazards were assessed.

9:15 Laser-Synchronized Imaging of Explosions

McNesby_KevinKevin L. McNesby, PhD, Team Leader, Detonation Science Team, Energetics Technology Branch, Lethality Division, Weapons and Materials Research Directorate, US Army Research Laboratory

The presentation focuses on methods of imaging explosions of solid energetic materials using camera-synchronized laser illumination. The techniques presented allow for mapping of temperature, pressure, chemical species, and energy deposition during and following detonations of explosives, using high-speed cameras as the main diagnostic tool.

9:45 Forensics Investigation of Advanced Battery Packs

Bryan Schultz, Spiers New Technologies

We discuss lessons learned from doing repair, reman and repurpose of advanced battery packs. As the leader in life cycle management of high-voltage battery packs, Bryan Schultz talks about lessons learned from studying post-incident batteries.

ENSURING SAFE BATTERY TRANSPORT

2:00 Chairperson’s Remarks

Robert Foster, JD, Marketing Manager, Rimkus Consulting Group, Inc.

2:05 Lithium Battery Transportation: Risks in Aviation

McLaughlin_JanetJanet McLaughlin, Director, Office of Hazardous Materials Safety, Federal Aviation Administration (FAA)

The risks of lithium battery transportation in the supply chain can only be effectively managed through a systems approach. The risk must be identified and communicated prior to transportation beginning, and not dependent on the mode of transport. A shift in risk approach of this magnitude will require all the relevant stakeholders to work together to achieve success.

2:35 New Investigation – Recycled Batteries in Shipment

Nowikowski_JosephJoe Nowikowski, Division Manager, Rimkus Consulting Group, Inc.

This talk will focus on a real-world investigation on recycled batteries in shipment. The methods of determining safety incident will be discussed.


3:05 Analyzing and Safely Transporting Lithium Batteries Suspected of Having Safety Defects

Richard_BobBob Richard, President, Hazmat Safety Consulting

Bob will share information on cases where he has assisted companies with assessing root causes of battery failures and share strategies for shipping them compliantly. Bob will discuss the latest packaging advances that can provide a safe and effective means for shipping damaged or defective batteries. He will also discuss modal requirements and how to coordinate with carriers, freight forwarders and regulators and recent efforts to amend regulations to reduce burden and enhance safety.

3:35 Sponsored Presentation (Opportunity Available)

3:50 Refreshment Break in the Exhibit Hall with Last Chance for Poster Viewing


4:30 PANEL DISCUSSION: Safe Damaged Lithium Battery Transport

Once a lithium-ion battery is damaged, it is critical to safely package and properly transport it to prevent further incidents. This panel of experts will discuss how to determine the risk factor of the damaged battery. Through analyzing the batteries’ pack design, state-of-charge, etc., scientists can determine how to properly ship the damaged batteries for further cause investigation, disposal, or recycling.

Moderator: Bob Richard, President, Hazmat Safety Consulting
