Symposium EN01-Electrochemical Capacitors and Related Devices—Fundamentals, Materials and Cell Design

This symposium will focus on electrochemical capacitors covering fundamentals, materials, and device design. Different classes of electrode materials will be covered including 2D materials (e.g., MXenes and chalcogenides), oxides, nitrides, polymers, metal-organic, and covalent-organic frameworks. Electrode materials with varying dimensionality (0D/1D/2D/3D) and their heterostructures can have a strong impact on electrochemical capacitor performance and will therefore be included in this symposium. In addition, studies on charge storage mechanisms in these electrode materials including electrochemical double-layer (EDL), pseudocapacitance, and intercalation pseudocapacitance will be discussed. The design of the cell is another important parameter that can be engineered to optimize the power and energy densities of the electrochemical capacitors. For example, symmetric, asymmetric (where one negative electrode is combined with a positive one to expand the voltage window), and hybrid (where one of the electrodes acts as a battery electrode) electrochemical capacitors will be part of the program. In addition, the symposium will cover microscale supercapacitors for on-chip energy storage, frequency filtering, and self-powered modules that couple microsupercapacitors with energy-harvesting devices for IoT and sensor network applications. Developing cost-effective fabrication methods to fabricate such microsupercapacitors is equally important . In addition, various electrolytes are being developed such as organic electrolytes, redox electrolytes, and solid-state electrolytes, and will be discussed. Modeling and simulation of supercapacitor performance is another aspect of capacitive energy storage that we will cover in this symposium.

  • Materials for supercapacitor electrodes
  • Fast battery-type electrode materials for hybrid devices
  • Charge storage mechanisms in electrochemical capacitors
