Large particles and contaminants may cause local hotspots in battery cells severely impacting safety and performance, making early detection of oversized particles an important analytical requirement. We will discuss how a combination of dynamic imaging and adaptive Laser diffraction can be used to detect oversized particles down to a few particles per million level.
This webinar will focus on the following key topics:
• Large particles and contaminants in electrode materials
• Laser diffraction for particle sizing
• Dynamic imaging for particle shape analysis and large particle detection
• Adaptive diffraction for large particle detection

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

Battery Selection Tutorial Course 1/3: Selecting your Cell and Cell Manufacturer(s)
After designing your product, you need to ensure the battery with which you are operating it will ensure the right performance and lifetime. When deciding this, narrowing down which chemistry (e.g. Li-ion, lithium primary, NiMH, etc.) best fits your product and which form factor are some of the first steps. Choosing a cell design (high-power vs. high-energy, for example) is another step and finally, finding the right cell manufacturer to fabricate your cells and packs. This webinar is the first in a three-part series on designing the right battery for your product. It will cover many of the key differences in chemistries, form factors, and cell designs and other best practices.
This webinar will focus on the following key topics:
• Choosing the right chemistry for your application
• Choosing the right form factor
• Choosing cell designs (e.g. high power vs. high-energy)Presenter

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
