(FREE) TORAY & VIRTUAL VEHICLE: Thermal Runaway Testing and Cause Analysis of an Automotive Li-Ion Cell

Part 1 focuses on the safety tests with large lithium-ion cells. We explain our test method and equipment to trigger and characterize a thermal runaway (TR). Then we present a case study with a large pouch cell which is brought into TR by over-temperature. We discuss the temperature curves, the voltage/resistance curves, gas releases and gas compositions.

Part 2 covers composition analysis of large lithium-ion cells to interpret what happened during high temperature test. We also conduct thermal stability analysis of charged electrode to know the temperature when exothermic decomposition and oxygen release from cathode start. From that information, we can obtain key parameters to control thermal runaway from material design point of view.

This webinar will focus on the following key topics:

• Methods for safety tests of large lithium-ion cells
• Thermal runaway of a large pouch cell caused by over-temperature
• Detailed analysis of the gas, which is released during thermal runaway
• Composition analysis of large scale lithium-ion cells
• Thermal stability of charged electrode

A PDF copy of the presentation will be sent to all attendees after the event.

(FREE) VOLTAIQ: Enterprise Battery Intelligence for Mobility Electrification

Electrification is the largest disruption to the transportation industry in its 125-year history – Enterprise Battery Intelligence software is key to the future of EV companies.

With over 160,000 EV battery-related recalls in Q4 2020 alone, EV companies are investing billions of dollars in the facilities, teams and infrastructure needed to gain a deeper understanding of their batteries and how batteries impact their business. Developing, manufacturing and operating high-quality battery-powered products requires a deep understanding of battery behavior in real-world application settings. To do this well, EV companies must marshal mountains of data spanning the test lab, production line and vehicles operating in the field.

This webinar will focus on the following key topics:

• Enterprise Battery Intelligence software is key to your company’s future
• Batteries can add tremendous value—or incur serious costs
• A deep and holistic understanding of batteries is required to innovate, qualify new batteries and materials, ensure on-time product launches, reduce risk, determine resale/second-life value, increase ROI, among other business critical issues

A PDF copy of the presentation will be sent to all attendees after the event.

PURDUE UNIVERSITY: Effects of Partial Nail Penetration on Li-ion Pouch Cell Operation

While many technological advancements have recently been made to ensure Li-ion batteries operate safely during normal cycling, many hazards exist when it comes to operation in abusive environments. Physical damage to batteries can lead to decreased performance and increased operating temperatures. This often causes thermal runaway, which in severe cases can lead to combustion and possibly explosion. In order to design cells in a way that mitigates these dangerous outcomes, it is important to understand what happens when a battery experiences physical abuse and continues to operate. This work focuses on the operational effects and indications for cells that operate in abusive environments where physical damage can be a concern.

This webinar will focus on the following key topics:

• Dynamic impact testing on Li-ion pouch cells
• Operational indications of cell damage
• Quantifying accelerated capacity fade due to physical damage
• Effect of increased operating temperature on coulombic efficiency
• Incremental capacity analysis for investigation into aging mechanisms

A PDF copy of the presentation will be sent to all attendees after the event.
