    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?

    The Potential Impact of a New U.S. Administration on Electric and Hybrid Vehicles

    The impact of the election upon government policy & the automotive industry is complicated and unclear. Fuel economy regulations are in place through Model Year 2021. We will explore the potential impacts on Model Years 2022-25 & beyond including the Midterm Review & the California Zero Emission Vehicle regulations which become more stringent in 2018.

    The strategies of the global automakers will be discussed including Volkswagen (as it attempts to recover from its diesel scandal) & the Detroit Three automakers that are focusing their expansion on markets outside North America. The role of China will also be assessed.

    Technology improvements and their implication upon cost will also be discussed, as will the full impact of electrification (including 48 volt technology) on the vehicle fleet.

    This webinar will focus on the following key topics:

    • Potential Legislative & Regulatory Changes Affecting Manufacturers and Consumers
    • Potential Responses by Industry & the New Administration to EPA Regulation for Model Years 2022-2025
    • Potential Responses from NHTSA Which May Still Rule on 2022-2025 Period
    • Reaction From California & the Impact of Its Zero Emission Vehicle Policies
    • Impact of Automaker Strategies Which are Global
    • Impact of Business & Technological Trends

    Understand and Prevent Battery Fires and Explosions – and Avoid Costly Failures Like the Samsung Note 7

    Modern batteries (eg Li-Ion) contain hazardous chemicals & they heat up during use: this combination always has the potential to cause fires & explosions. This presentation will focus on improving the understanding of how these incidents occur, what can be done to avoid them & how the risk can be minimized during early stage design.

    The Samsung Note 7 phone & Boeing Dreamliner airplane fires are very costly examples of how even large corporations fail to understand the potential fire risk of batteries.

    The solution lies in knowledge of heat generation rate during normal use & information about safe boundaries such as temperature, discharge rate & overcharge, in realistic situations that represent actual use conditions. Data from commercial batteries of different types will be used to illustrate these points.

    A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.

    This webinar will focus on the following key topics:

    • Why battery fires & explosions occur
    • How to design safer batteries though understanding of heat generation
    • Video evidence of batteries under explosive conditions
    • How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
    • Laboratory instruments suitable for testing and data generation

    Dr. Jasbir Singh – Managing Director at Hazard Evaluation Laboratory

    Jasbir is a chemical engineer specializing in thermal hazards and calorimetry, traditionally for the chemical industry but now increasingly involved in battery safety, especially Li-ion EV and related types.

    A graduate of Imperial College (London), where he undertook PhD into combustion and explosions, his experience includes many years in process design for the chemical and petrochemical industries. He is currently developing test methods and instruments for use in design of battery thermal management systems.

    Solid Electrolytes and Bulk Scale Solid-State Batteries

    Recently, the push to move beyond Li – ion battery technology has grown. Several advanced battery technologies & chemistries have been identified as promising candidates including i) solid-state batteries with Li metal anode, ii) Li – S chemistries, iii) Li – air(oxygen), and iv) flow batteries. Although an engineered solution using liquids may be possible for some of these options, a solid electrolyte is an enabling technology for each of these beyond Li – ion alternatives. This webinar will introduce the operating principles of each of these cell technologies and solid electrolytes will be discussed in this context. The requirements of a solid electrolyte will be outlined & several state of the art solid electrolytes will be compared. Recent technical progress towards the fabrication of solid-state batteries will be reviewed. Finally, an overview of market applications for solid-state will be presented.

    This webinar will focus on the following key topics:

    • Overview of beyond Li – ion battery technologies enabled by solid electrolytes
    • Comparison of state of the art solid electrolytes
    • Recent technical progress towards solid-state batteries
    • Review of market applications for solid-state batteries
