Symposium EN05—Emerging Materials for Electrochemical Energy Storage Devices—Degradation and Failure Characterization—From Composition, Structure and Interfaces to Deployed Systems

Industry challenges with fielding safe and reliable rechargeable energy storage technologies are increasing as new higher specific energy devices are introduced into the growing global marketplace. Structural and interfacial degradations, as well as other failure mechanisms in electrochemical energy storage technologies, dictate a path for developing novel materials resilient to stressful operating conditions while improving overall performance, environmental impact, and safety. Fast charge and extended use are examples of operating conditions that drive materials towards early performance degradation which may lead to reduced safety margins. A fundamental understanding of processes at the materials level, both structural and interfacial, that leads to specific degradation and failure modes is required to develop innovative materials capable of performing in diverse operating environments. Mitigation strategies from a materials perspective are also critical to reduce the risk associated with degradation and failure in large energy storage systems. Therefore, the focus of this symposium is an increased understanding of the interfaces, intercalation, degradation, and failure associated with advanced electrochemical energy storage technologies. The symposium's main discussion topic is emerging materials for improved performance, safety, sustainability, and reliability of all types of rechargeable batteries and supercapacitor devices. A secondary focus is degradation and failure mechanisms under stressful operating conditions in various industrial applications. Emphasis will be given to materials characterization, diagnostic, and prognostics from in-situ, in-operando, and post-mortem techniques. The symposium will bring together a diverse group of interdisciplinary industry and academic material scientists and engineers to fast-track the development of inherently safe materials for electrochemical energy storage devices.

Topics will include:

  • Emerging materials for improved performance, safety, sustainability and reliability
  • Electrode-electrolyte interfaces
  • Intercalation materials
  • Electrolyte degradation and gas production
  • Degradation of electrode materials
  • Failure and degradation modes of fast-charged batteries
  • High cycle-life performance
  • Diagnostics and prognostics
  • State of health monitoring, trending, analysis, and modeling
  • Lithium plating
  • Failure initiation and propagation
  • Hazards analysis and safety testing
  • A tutorial complementing this symposium is tentatively planned.
