About Company:

We specialize in electrostatics including their implementations into commercial operations and devices. 

Summary of Project:

The investigation is to determine the best balance for cost and actual storage volume capacity of different material combinations and specifications for double layer supercapacitors (DLSC). The research is based on traditional commercially available, as well as proposed super capacitor solutions. The study is also to focus on actual manufacturing techniques, as well as the relative availability of identified materials. The design of the DLSC is to allow a robust and economically constructed product with good energy density, and simplified manufacturing process as the primary focus, as opposed to the current broad interest critically focused on energy density.

The end use application for this research collaboration is for implementation into grid storage applications for response demand and ancillary services systems.

Research Objectives/Sub-Objectives:

  • Determine the most beneficial exchange of energy density and cost, as a relation of material cost and energy density (surface area/ ionic transfer capability and tolerance)
  • Determine the relative availability and cost of materials
  • Determine construction and adhesion methods of material, and process

Methodology:

    • Analyse current baseline energy densities of double layer super capacitors utilizing traditional methods of constuction and materials, i.e. etched aluminium foil for low voltage applications, activated carbon (coconut, lignite, bituminous,wood), electrolyte (organic, ionic fluids, salts) and dielectric (ceramic, plasitic film, paper) to determine the most beneficial relation as a cost for storage metric, where energy denisty is a feature and not the pivotal determant   
    • Analyse assembly techniques for material application, (slurry, solvent, pressed, sprayed) for the design of a simplified construction and assembly

    Expertise and Skills Needed:

    • Advanced understanding of electrostatics and material science specific to these devices. Understanding the makeup of current and traditional DLSC’s, the materials used in their construction as well as the construction process
    • Understanding of combinational effects of different material combinations including voltage tollerances, energy density, material availability and cost, construction and assembly
