Symposium EN08-Progress in Understanding Charge Transfer at Electrochemical Interfaces in Batteries

The quantity, rate and repeatability at which energy can be stored and accessed in batteries is regulated by charge transfer at the electrode interfaces. This symposium will cover new advances and emerging concepts for probing, understanding and controlling the transfer of ions and electrons across battery electrode interfaces. Phenomena of interest include but are not limited to determination of intrinsic barriers to charge transfer, the structure, composition and properties of evolving interphases active in transfer, and materials design and synthesis of both electrolyte and electrode resulting in enhanced and resilient transfer. Additionally, efforts focusing on integrating computational and experiment to deepen our knowledge of a material’s role in charge transfer and in situ and operando methods to characterize the interface/interphase evolution are of particular interest. Emphasis will be placed on energy storage applications, where the interaction strengths of redox active ions with the electrode are a critical factor for battery efficiency and resiliency. Symposium contributions are encouraged that address basic materials science hypotheses related to charge transfer processes across heterogeneous interfaces or address challenges in the development of in situ/operando measurements and computational modelling for interrogating the charge transfer process. This symposium will explore state-of-the-art research on interfacial processes across the battery technology spectrum, bringing together materials scientists and engineers from numerous disciplines.

Topics will include:

  • Electrode-electrolyte interphase identity, properties, and temporal evolution
  • Electrode and electrolyte material design for interface and interphase resiliency
  • Characterization of interfaces and interphases including in situ/operando methods
  • Computational modelling of charge transfer and interphase formation and properties
  • Ion transport mechanisms at heterogeneous interfaces
