Silicon (Si) is an attractive alternative to graphite due to its high theoretical capacity of 3500 mAh-g-1 and its high abundance on earth. Unfortunately, Si is plagued by significant volume expansion during charge/discharge, upwards of 300%. As a result, researchers and companies have focused their attention on mitigating the disadvantages of Si. With various methods the aim is to create a Si based anode that has a stability comparable or better then graphite. With increasing interest, it is important to discuss and determine abuse testing and failure analysis techniques that can effectively determine the durability of these new anodes.
This webinar will focus on the following key topics:
• Why is it important to look at alternative anodes to graphite?
• The advantages and disadvantages of Si based anodes
• Creation of new anodes to alleviate the disadvantages of Si
• Customized abuse testing and failure analysis of Si based anode cells

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

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

Accelerating Launch of New Battery Technologies by Expediting Samples Through Collaborative Partnerships
Polaris is a processing lab that accelerates new lithium ion battery developments resulting in faster delivery of samples. It provides processing services to accelerate the optimization of recipes for battery developers. Using its services, customers can avoid delays in launching products due to internal funding and staffing constraints.
Services include anode and cathode electrode mix and coat trials, pouch stack cell assemblies, cell and material analytical testing services, business advisory services, and a link to high volume production.
Two major roadblocks facing battery technology companies are addressed: 1) Startups lack staffing, process knowledge, funding, and equipment to develop samples, and 2) Commercialization of new battery technologies is capital intensive and takes long time to pass quality standards
This webinar will focus on the following key topics:
• Significant new material inventions in lithium ion and other advanced battery chemistries in the US
• Two primary issues or “gaps” in getting these technologies to the market
– generating samples for investors, customers and internal engineering evaluation and optimization
– building a battery factory and gaining product and quality system approval (a huge undertaking)
• Polaris Battery Labs Capability Overview for samples and commercialization
• Partner Profile; Carestream Heath as a contract coating partner to reduce time-to-market and risksPresenter

Maximizing Battery Performance and Reliability for Electric Vehicles and Energy Storage
FREE Webinar – Voltaiq is a proud sponsor of this event.
As automakers and utilities transition away from non-renewable energy sources, batteries have become essential for efficient energy storage and delivery. Companies are working intensely to deliver higher capacity and more robust batteries to power their products, but ad hoc development processes cannot keep pace with the volume of battery data being generated. In addition, understaffed battery development teams are unable to leverage their data to accelerate development or improve production and manufacturing.
In this webinar, we will outline the challenges that the battery industry is facing and how big data analytics can virtually eliminate manual data management and provide powerful capabilities that deliver rapid insights into a battery’s design that dramatically accelerate the development process and results in products with greater performance and reliability.
This webinar will focus on the following key topics:
• Recognizing the challenges and bottlenecks in battery development today
• Automating the battery data collection, data cleaning, and data management process
• Identifying design issues earlier with predictive analytics
• Leveraging metadata to understand the impact of materials, processes and test conditionsPresenter
