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

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

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 risks

Battery Selection Tutorial Course 3/3: Integrating Your Battery Into Your Product – Designing for Worst-Case Scenarios
The last part in Exponent’s three-part series, this webinar will focus on the finished product from the viewpoint of the battery. How can you best protect your battery within your device? Is your battery going to be user-replaceable? If you’re creating multi-cell packs, how should they be separated from (yet still connected to) each other? Should a thermal event occur, how can you prevent that from cascading through the whole pack? This webinar will help to answer many of those questions, and discuss design questions to help safeguard your battery pack throughout its entire lifecycle.
This webinar will focus on the following key topics:
• Creating multi-cell packs
• Containing thermal runaway events
