    Augment Your Battery Research With Non-Ambient In Operando XRD

    Recently, in operando research on batteries with XRD system in room temperature has provided great understanding on the dynamic migration of the electrode materials during the charge cycle. However, a battery may work perfectly at ambient temperature, but actual environment may cause unexpected performance degradation and safety risks. To investigate battery stability under non-ambient conditions, we are introducing 2 variable temperature electrochemical cell (VTEC) battery stages with heating and cooling feature between -10°C and 70°C on the Empyrean XRD platform. In combination with comprehensive instruments control software and powerful data visualization and analysis tools made for large XRD datasets in HighScore Plus, we provide the most advanced in operando in situ solutions to accelerate your battery research.

    This webinar will focus on the following key topics:

    • Advanced non-ambient in operando studies on batteries with Empyrean XRD system
    • Synergy amongst potentiostat, Empyrean and temperature controller
    • Fully automated data analysis with HighScore Plus
    o electrode phase identification and quantification
    o crystal structure and defects analysis
    o cluster analysis
    o intuitive and powerful visualization tools made for in-operando experiments

    Cause Analysis for Performance Degradation of LIBs and Analytical Methods for All Solid-State Batteries

    In Part 1, we showcase the analytical approaches of cause analysis for performance degradation of Lithium-Ion Batteries (LIBs). By the combination of electrochemical and teardown analysis, we’ll get you to find the main cause of performance degradation, and help you improve the materials optimized for the charge/discharge conditions.

    Part 2 covers various analytical methods of sulfide/oxide based All Solid-State Batteries (ASSBs), in terms of composition of solid electrolyte, coverage ratio of coating layer on cathode, and component distribution in cells. In addition, brand-new analytical methods such as in situ SEM will be presented, which will expedite your R&D.

    This webinar will focus on the following key topics:

    • Cause analysis for performance degradation of LIBs
    • Comprehensive estimation of performance degradation, and electrochemical and teardown analysis of LIBs
    • Useful analysis for material development/process optimization of ASSBs
    • Use cases for sulfide/oxide based solid electrolyte, and coating layer on cathode
    • Cutting-edge analytical methods: in situ analysis/micro analysis

    Fundamentals of Electrochemical Impedance Spectroscopy and Application to Li-Ion Batteries

    Electrochemical Impedance Spectroscopy (EIS) is a high-information content technique that provides insight into complex systems. EIS has gained tremendous popularity since innovation with the line of Frequency Response Analyzers from Solartron Analytical – but remains intimidating to many users. Join this webinar to gain confidence in your understanding of the technique itself and its application to the Li-Ion battery activity chain. EIS is used to: 1.) study diffusion characteristics and SEI formation during material development, 2.) identify degradation modes, ESR, State-of-Charge during cell characterization, and 3.) rapid grade State-of-Health during modules evaluation.

    This webinar will focus on the following key topics:

    • Fundamentals of data acquisition and data analysis of EIS
    • How EIS theory is applied in practice by beginners and experts
    • The value of EIS as a tool in evaluation of Li-ion batteries
    • How AMETEK’s portfolio meets uniquely defined needs at different points of the value chain

    Passive Mitigation of Thermal Runaway Propagation in Dense 18650 Lithium Ion Cell Assemblies

    Utilization of lithium ion batteries (LIBs) in various applications has been growing exponentially. LIBs offer some distinct advantages including high energy density, outstanding efficiency, long lifespan, and fast charging capability. Probably, the main disadvantage of LIBs is that a small deviation from normal operating condition may result in rapid self-heating accompanied by ejection of large quantities of flammable materials, which can cause fire or explosion. The failure process becomes more dramatic when many cells are arranged in large arrays in order to fulfill the power requirements by most of applications. Failure of a single cell can release sufficient energy to trigger failure into adjacent cell, which subsequently propagates throughout the entire array. In this webinar, a set of passive strategies to mitigate failure propagation will be presented. The dynamics, heating rates, gaseous emissions, and energetics of thermally induced thermal runaway propagation in dense arrays consisting of 12-15 fully charged 18650 lithium ion cells have been quantified to determine the effectiveness of these passive mitigation strategies.

    This webinar will focus on the following key topics:

    • Thermal runaway in lithium ion batteries
    • Thermal runaway propagation in lithium ion battery packs
    • Hazards associated with failure propagation
    • Passive mitigation strategies
