2022 MRS Fall Meeting & Exhibit

Symposium EN05-Solid-State Batteries—Life, Safety and Scalability

Utilization of a solid electrolyte offers the promise of safety, increased energy density, fast charge, and reduced cost. As a result, all eyes are on the solid-state battery (SSB) for applications ranging from cell phones to electric vehicles and even grid energy storage. In recent years, our fundamental understanding of interfacial resistance, Li dendrite growth, ion transport in solid media, and advanced fabrication techniques has grown substantially. However, a disconnect has become apparent between the lofty projections of SSB technology and what is realistically obtainable. As such, the commercialization of SSBs has been obstructed by several critical challenges. In addition, despite limited testing, safety of SSBs is taken as a fundamental truth. With this expectation of higher energy density, the statement of “safe” must be further examined. Significant materials and fabrication challenges remain on the path to widespread commercialization and implementation of SSBs.

This symposium will highlight recent advances in fundamental research on materials and interfaces in SSB, with the aim of calling attention to the need for discussion in the areas of achievable energy density, performance, manufacturability, cost analysis, and inherent safety. Research including materials design and synthesis, device fabrication and diagnosis, cutting-edge in situ and ex situ characterizations, manufacturing methods and life cycle analysis, state-of-the-art atomistic, continuum, and multi-physics modeling and simulations, etc. will be invited and encouraged. This symposium will further develop a multidisciplinary approach to the understanding of material science limitations in SSBs, while addressing key challenges in this growing research space, with the goal of widespread SSB technology adoption.

Topics will include:

  • Safety (thermal management, package design, fire retardant materials, etc.)
  • Device integration, ancillary component requirements (stack pressure, thermal management, etc.)
  • Novel solid-state electrolytes fabrication and properties (sulfides, oxides, halides, hydrides, nitrides, inorganic-polymer composites, polymers, etc.)
  • Advanced fabrication processes toward manufacturability (3D printing, coating, etc.)
  • Cost analysis for practical high-volume production of solid-state batteries (cells, modules, packaging)
  • Predictive thermal modeling of abuse scenarios (finite element analysis, etc.)
  • Theoretical understanding of solid-state batteries and advanced characterization (DFT, MD, continuum and multi-physics modeling, etc.)
  • Interfacial studies between solid electrolyte and electrodes (stability, SEI formation, advanced structural and morphological methods, theoretical calculations, etc.)
  • High energy cathode, anode, and composite materials for all-solid-state batteries
