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
• Applications

Update on Zinc Hybrid Cathode Battery Technology: Lessons Learned from Demo Projects with Major Utilities in US & Europe
With no economical means to store energy, the utility distribution network has typically been overbuilt and continually expanded to serve peak demand, though only a fraction of that infrastructure is used on an average day.
Working closely with utility partners like AEP and Con Edison, Eos Energy Storage has evaluated the economics of battery storage on the distribution system, with compelling results. Using first-hand knowledge of system costs and specifications, it was found that a utility-owned battery system can break even with a conventional T&D upgrade of ~$5M, or less when monetizing available market revenues.
In this webinar, Eos will share an update on commercialization of its zinc hybrid cathode battery technology and share lessons learned from deployments with major utilities in the US and Europe, from initial business case analysis to commissioning a turnkey product.
This webinar will focus on the following key topics:
• Discuss how energy storage can be leveraged as a utility distribution asset and market resource
• Share Eos’s experience in deploying energy storage systems at utility sites in the US and Europe
• Update on performance and path to commercialization for novel zinc hybrid cathode battery technology

Stability of Li7La3Zr2O12 Garnet Solid-State Electrolyte Against Metallic Lithium
Energy storage demands will require safer, cheaper and higher performance electrochemical energy storage. While the primary strategy for improving performance has focused on state-of-the-art Li-ion batteries, this work seeks to develop solid-state batteries employing metallic Li anode. Recently, the ceramic electrolyte, Li7La3Zr2O12 (LLZO) cubic garnet, has shown promise owing to its unique combination of properties such as high Li-ion conductivity and electrochemical stability. Generally, LLZO is synthesized through powder processing and sintering at high temperature to produce dense membrane. Processing of the ceramic materials produces internal and surface flaws which will inhibit lithium transport creating localized current density and control the stability against Li dendrite propagation. This presentation will discuss new improvement in methodology to evaluate the integrity of LLZO membrane.
This webinar will focus on the following key topics:
• Methodology to evaluate the integrity of LLZO by identifying the microstructural flaws and their impact on mechanical properties
• DC cycling, EIS, XPS will be shown to determine the reactions that govern the maximum current density
• Correlate the electrochemical stability and critical current density with defects in polycrystalline solid state LLZO electrolyte

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?
