Spectroscopic techniques are powerful non-destructive tools to monitor Nafion membranes, catalytic coatings, and other components of a membrane electrode assembly during production of proton exchange membrane fuel cells (PEMFC). This presentation will discuss X-ray diffraction, X-ray fluorescence, and near-infrared spectroscopy techniques that can be used for materials characterization in development and production. Applications measuring nanocatalyst size, nanocatalyst loading, membrane hydration, and more will be provided as examples.
This webinar will focus on the following key topics:
• Proton-exchange membrane fuel cell
• X-ray diffraction
• X-ray fluorescence
• Near infrared spectroscopy
• At-line characterization

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

Electrochemical Impedance Spectroscopy and Its Application to Battery Analysis
Electrochemical Impedance Spectroscopy (EIS) is a well-established experimental technique that has applications in coatings, corrosion, sensors, electrochemical double layer capacitors, batteries among others. The power of EIS partly comes from its ability to access a very wide range of frequencies (typically from MHz to μHz). For batteries, parameters such as the internal resistance, electrode surface capacitance and leakage are accessible at different frequencies across the spectrum. This allows EIS to gather all the relevant information with a single measurement. In this webinar, we will briefly introduce EIS and cover its application to batteries. We will talk about how to analyze typical data and how to gather the relevant information. We will further talk about available instrumentation and their limitations.
This webinar will focus on the following key topics:
• What is impedance spectroscopy?
• What can impedance spectroscopy do for Battery analysis?
• How can capacitance, internal resistance and leakage be determined using EIS?
• What are the instrumental requirements and limits?Presenter

Energy Storage RTE Tutorial Course 3/3: Total Battery System RTE – Ranking and Comparison of Different Battery Chemistries
RTE impacts of HVAC/Ventilation and Inverters will be described. Batteries generate heat, and this must be dissipated by system cooling and/or taken out of the system. Heat generated can be calculated by looking at IR heating and that generated (net) by exothermic reactions. Examples will include LFP, Li-NMC, Lead Acid and Nickel batteries, both when they are fresh, as well as at their end of useful life. The overall ancillary equipment energy usage will be listed for these systems, and a % RTE loss will be calculated for both nominal rate and high rate applications. Commentary will be provided for other systems. RTE will be summarized and ranked for most energy storage battery chemistries including ZA, NaS, LiS, Saltwater, Liquid Metal, Zinc Bromine and Fuel Cells.
This webinar will focus on the following key topics:
• RTE impacts of Inverters and HVAC
• RTE impacts for ancillary equipment for different systems
• RTE numbers for most battery systems being considered for energy storagePresenter

Preventing Li Ion Battery Failures From a Manufacturing and Design Perspective
How can you be proactive and make sure your cell supplier is the right one and you don’t end up with thermal events and field failures? Is it enough to qualify a cell manufacturer according to industry standards? The answer is that the majority of compliance based testing is related to abuse tolerance. However, the vast majority of field failures do not occur under abuse scenarios, but happen under normal operating conditions due to manufacturing flaws or design and system tolerance issues that cause internal shorts. In this webinar, you will learn about common lithium ion battery failure modes and how to be proactive in preventing these.
This webinar will focus on the following key topics:
• Gain an understanding of lithium ion battery failure mechanisms and the pathway to thermal events
• Learn how cell design impacts battery safety and reliability
• Learn the basic steps in a lithium ion cell manufacturing process, and how the process controls affect safety and reliability
• Come away with a checklist to qualify your cell manufacturerPresenter
