As a sustainable power source for automobiles, PEFC (Polymer Electrolyte Fuel Cells) have been investigated for further improvement of their durability. In general, the degradation of PEFCs is caused by various factors under operation. Thus, a comprehensive analysis is required to understand these important degradation factors.
This presentation will share evaluation by multi-analysis method of degraded PEFCs after their cycling. It was found that Si was contaminated in the cathode catalyst layer, and that Pt particles were enlarged in the cathode catalyst layer near the cathode gas outlet area. In addition, it was found that the degradation of the ionomer was more likely to occur near the cathode gas inlet area.
This webinar will focus on the following key topics:
• Polymer electrolyte fuel cells (PEFCs)
• Durability test
• Ionomer
• Comprehensive degradation analysis

Preventing Thermal Runaway in Energy Storage Systems (ESS)
From air transportation to electric vehicles and most recently “Hover Boards”, our industry is painfully aware of the over-discharge malfunctions associated with high-energy lithium-ion batteries, yet according to recent studies, nearly 70% of all Energy Storage Systems currently deployed are lithium-ion. Avoiding the pitfalls of utilizing greater energy density in larger installations is what will be discussed. Michelle will walk through the recent innovations from materials and process tracking in battery manufacturing to comprehensive control of cells in a fully deployed system. Incorporating lessons learned from recent failure investigations by the NTSB and FAA as well as new DoE mandates, Michelle will discuss how to achieve and in some areas surpass the new emerging safety certifications for a multi-megawatt energy storage system.
This webinar will focus on the following key topics:
• Making batteries safe or making safe batteries? (control & mitigation)
• Cell manufacture tracking, certification and response
– NTSB & DoE analysis and current situation
• Incorporating advanced battery management systems (BMS)
– Active cell dynamic balancing
– Cell replacement (hot-swapping)
– System reconfiguration
– Energy density scalabilityPresenter

Avoid Battery Explosions and Fires – With Right Data and Better Designs
Modern Li Ion batteries contain hazardous chemicals and heat up during use – this combination always has the potential to cause fires and explosions. This presentation will focus on improving the understanding of how such incidents occur, what can be done to avoid them and how the risk can be minimized during early stage design.
The solution lies in knowledge of the heat generation rate during normal use, and information about safe boundaries such as temperature, discharge rate & overcharge in realistic situations that represent actual conditions of use. Data from commercial batteries of different types, including videos of batteries undergoing thermal runaway, will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:
• Why battery fires and explosions occur
• How to design safer batteries through understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
• Laboratory instruments suitable for testing and data generationPresenter

Lithium Ion Capacitors – Combining Energy with Power
FREE Webinar – JSR Micro, Inc. is a proud sponsor of this event.
Lithium Ion Capacitors (LIC) are hybrids of electric double-layer capacitors (EDLCs) and lithium ion batteries (LIB). Combining the reversible non-Faradaic cathode from an EDLC and the reversible Faradaic anode from an LIB results in an ultra or super capacitor with significantly increased energy density, improved float performance and low self-discharge rates. Avoiding the lithium metal oxide cathodes from LIB’s improves the inherent safety and eliminates Cobalt content, however still combines aspects of energy & power of both cell types. The Faradaic intercalation/deintercalation reactions at the anode are capable of generating a significant amount of charge, while the non-Faradaic electrostatic storage of the electrical energy formed at the interface of the electrode and the electrolyte, known as an electric double layer, results in fast charge and discharge capabilities for hundreds of thousands, if not millions of cycles.
This webinar will focus on the following key topics:
• What is an LIC? Technology Introduction
• Key Benefits
• Safety
• EDLC vs LIC
• ApplicationsPresenter

Battery Selection Tutorial Course 2/3: Beyond the Standards: Device-Specific Testing
After choosing your cell and manufacturer (Part 1 of this series), most likely, they will have passed the tests of various standards organizations. However, depending on your operating environment, you may need to go above and beyond the baseline to ensure your product operates as intended. This webinar is Part 2 in a three-part series and will review a variety of factors to consider in your device-specific testing, including designing tests to predict the outcomes of various user-abuse scenarios, understanding the mechanisms of gas generation, capacity retention based on different voltage windows, and what happens if you need to cycle your cells outside of their operating range (outside in an Arizona summer or Minnesota winter, for example).
This webinar will focus on the following key topics:
• User-abuse scenarios to prevent against
• Causes and effects of various gas generation mechanisms
• Voltage limitsPresenter
