  Non-Destructive Testing: Insuring Safety, Reliability, and Reducing Cost of Li Batteries

  Non-destructive non-contact electromagnetic, ultrasonic, holographic interferometry, gas discharge visualization, and combined methods are innovative tools for successful coordination of stages of R&D, manufacturing, and applications of Li batteries. Deployment of automated non-destructive quality assurance technology at every stage of the manufacturing process will increase the reliability and safety of batteries, while lowering overall manufacturing costs.

  This webinar will focus on the following key topics:

  • Physical principles of the non-destructive & non-contact methods for evaluation and testing of Li batteries during production:
  – Initial materials, including nano-structured powders of electrode materials
  – Polymer and solid inorganic electrolytes
  – Properties of electrodes during coating, including the resistance of interface between current collectors and electrode mass
  – Multi-layered electrode structures, as Jelly roll dry electrode structure
  – Final product
  • Design of equipment for non-destructive testing
  • Examples of using the non-destructive methods in Li batteries, super-capacitors, solar cells, chemical industry, and other industries (example – evaluating the properties of the cement)
  • Benchmarking, and the market of application for non-destructive, non-contact testing

  Development and Testing of Electric Drives and Battery Management Systems

  Many types of hybrid and electric drive (E-Drive) control systems are being developed for platforms in several industries. These systems also use Battery Management Systems (BMS) to handle their demanding power needs. However, the development of these technologies brings increased system complexity, evident in the many platform variants and control algorithms of various electronic control units (ECUs).

  dSPACE provides comprehensive solutions for E-Drive or BMS development, from providing proper hardware I/O interfaces for prototyping/testing these applications to real-time models for simulation of these controlled systems. There is also the need for consideration of power and safety requirements and precision of the simulation or control capability.

  This presentation will cover RCP and HIL systems and models for the development and validation of E-Drive and BMS control systems. Specific implementation techniques for model processing and interfaces in real-time along with critical power interface and electrical hardware functionality will be shown.

  This webinar will focus on the following key topics:

  • Real-time Simulation Models for Electric Motors and Battery Systems
  • Rapid Prototyping hardware for E-Drive and BMS Development
  • Hardware-in-the-Loop (HIL) Simulators for testing E-Drive/BMS Systems

  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
