Passive Mitigation of Thermal Runaway Propagation in Dense 18650 Lithium Ion Cell Assemblies
Utilization of lithium ion batteries (LIBs) in various applications has been growing exponentially. LIBs offer some distinct advantages including high energy density, outstanding efficiency, long lifespan, and fast charging capability. Probably, the main disadvantage of LIBs is that a small deviation from normal operating condition may result in rapid self-heating accompanied by ejection of large quantities of flammable materials, which can cause fire or explosion. The failure process becomes more dramatic when many cells are arranged in large arrays in order to fulfill the power requirements by most of applications. Failure of a single cell can release sufficient energy to trigger failure into adjacent cell, which subsequently propagates throughout the entire array. In this webinar, a set of passive strategies to mitigate failure propagation will be presented. The dynamics, heating rates, gaseous emissions, and energetics of thermally induced thermal runaway propagation in dense arrays consisting of 12-15 fully charged 18650 lithium ion cells have been quantified to determine the effectiveness of these passive mitigation strategies.
This webinar will focus on the following key topics:
• Thermal runaway in lithium ion batteries
• Thermal runaway propagation in lithium ion battery packs
• Hazards associated with failure propagation
• Passive mitigation strategiesPresenter

De-risking ESS Projects by Improving Safety & Availability
Battery energy storage systems (BESS) ensure grid stability and align supply with demand by storing surplus energy during periods of abundance and discharging it only when needed.
But they require a lot of monitoring: individual battery cells vary in quality and age, and these cell imbalances increase stress on the system. This leads to wasted energy and increased downtime. At the same time, regulators are paying attention and developing safety standards that apply to battery storage and the risks involved. In this webinar, you’ll gain a deeper understanding of how analytics can help you identify and mitigate battery performance and safety risks along the entire lifecycle, from design over commissioning & operation to de-commissioning.
This webinar will focus on the following key topics:
• De-risk deployment and operators of BESS from design over commissioning & operation to de-commissioning
• Why monitoring battery systems with advanced analytics is so important
• How to identify issues with your system early on
• How to optimize BESS performance
• Industry best practices and emerging trendsPresenters

Battery Management System Impacts on Energy Storage
Battery management systems impact the utility, effectiveness, and life of an energy storage system. Passive balancing is less expensive than active balancing, but weaker cells or modules may need to be replaced near the end of the ESS’s lifespan. Active balancing transfers energy from stronger to weaker cells, but at a higher system cost and design complexity.
System down time is associated with both approaches and carries such a high opportunity cost that innovations in this area may be of greater importance than the type of balancing being employed.
Join Nuvation Energy CEO Michael Worry for an exploration of the current state of the art in battery cell balancing, and how BMS innovations will impact the future of stationary energy storage.
This webinar will focus on the following key topics:
• A stationary ESS orientation on battery management
• Understanding balancing-related down time
• Comparing active and passive balancing
• Innovations in battery managementPresenter
