As demand for energy density in battery cells increases, minimizing the safety risk to consumers during the battery design and manufacturing process and managing the complex recall process when lithium-ion battery failure occurs is becoming ever more critical. At the in-person and virtual 13th Annual Cambridge EnerTech Battery Safety Summit, technical experts and industry leaders from around the world will convene to the discuss the latest approaches for improving lithium-ion battery safety and reducing the risk of battery failure while maximizing energy efficiency.
With more than 25 years of experience assessing battery failures, Exponent offers unparalleled, multidisciplinary insights to help lithium-ion battery manufacturers improve battery safety throughout the product lifecycle. Don't miss presentations on battery recall and failure behaviors of lithium-ion batteries from our experts Troy Hayes, Ph.D., P.E., and Sophie Lee, Ph.D., on Nov. 7. More details below.
"Navigating a Battery Recall: Managing Risk and Protecting Your Brand Name"
TUESDAY, NOV. 7 | 10:00 A.M. EST
Speaker: Troy Hayes, Ph.D., P.E., Practice Director, Director of Asia Offices and Principal Engineer, Materials & Corrosion Engineering
Lithium-ion batteries fail on rare occasions and can cause potential risk for users and peripheral systems. In a battery recall assessment, original equipment manufacturers (OEMs) should act to minimize the risk to consumers, while providing sound technical solutions to potentially recover and replace batteries. This talk will discuss the recall process and important aspects for OEMs to consider when managing a recall, including: Consumer Product Safety Commission interactions, root cause analysis, future failure predictions, risk analysis to determine whether a recall is warranted, recall scope limitation through traceability, ensuring that replacement products resolve the issue at hand, and minimizing future risk.
"Application of Calorimetry and Computed Tomography to Failure Behaviors of Lithium-ion Batteries Under Different States of Charge"
TUESDAY, NOV. 7 | 2:30 P.M. EST
Speaker: Sophie Lee, Ph.D., Senior Associate, Polymer Science & Materials Chemistry
Understanding the failure behaviors of lithium-ion batteries can help to improve battery safety by providing guidelines for the design in the battery management system, regulations for transportation of batteries and battery-containing devices, as well as the root-cause investigation in battery-involved accidents. Accelerating rate calorimetry was used to study the influence of lithium-ion battery energy and state of charge (SOC) on the thermal behavior and failure mode. Characteristic events were found to occur at much lower temperatures and faster rates with increased cell SOC. X-ray computed tomography was then applied to understand and reveal the fingerprints of cell failure.
