    Solid-State Batteries – The Key Enabling Technology in Advanced Electric Vehicles

    The ‘EV Everywhere Grand Challenge’ has led to extensive research and development of battery technologies with high energy density. To date, state-of-the-art Li-ion batteries (SOA LIBs) based on alkali metal ion intercalation cathodes and anodes have been widely adopted in plug-in hybrid and niche high performance electric vehicles. However, concern with the ultimate limits of SOA LIBs related to their energy density, weight and safety suggests the need for alternatives over the long term. Solid-state batteries (SSBs) have been recognized as an ideal solution that can enable energy densities beyond those of SOA LIBs by utilizing Li metal anode and high voltage cathode, while delivering long cycle life and improved safety. As the key component of SSB, solid-state electrolyte (SSE) replaces the porous separator/ liquid electrolyte to act as a physical barrier and mechanically suppress the formation and penetration of Li dendrites. However, successful development and commercialization of SSBs requires fundamental research related to enhancing the SSE ionic conductivity, stabilizing the     electrolyte/ electrode interfaces, cell and pack manufacturing methods, development of battery management systems, and efficient battery pack designs. In this webinar, the practices and principles that have been proposed for dealing with core problems related to SSBs as well as future research avenues that will encourage the adoption of SSBs in real application will be discussed.

    This webinar will focus on the following key topics:

    • The microstructure role and SSE composition on the Li+ conduction behavior
    • Design and development of an effective electrode-electrolyte interface in SSBs
    • Mechanistic origins of Li dendrite growth in SSEs and approaches to mitigate the dendrite penetration
    • Manufacturing challenges related to mass production of SSBs

    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
