Optimizing the performance of energy storage units (batteries) and the efficiency of energy conversion units (fuel cells) is the key challenge in the profitable transformation of renewable energy sources into electricity.

Widespread interest has emerged to improve the storage of intermittent renewable energies, such as wind and solar power, or to increase the efficiency of portable devices for off-grid electrical use, such as those in hybrid and electric vehicles or in (prototype) fuel cell vehicles.

Merely keeping track of scientific developments, and applying them, is insufficient to remain abreast or even take the lead in this rapidly evolving field.

For leading companies in the electrochemical sector, in-house proprietary innovations are of vital importance to design the best-performing, most-efficient, lightest, smallest, and safest solutions for energy storage and conversion.

GeoDict for Electrochemistry

GeoDict® for Electrochemistry

Simulations constitute a convenient and cost-efficient alternative to physical experiments which are generally difficult and expensive in time and resources.

Innovative energy storage devices can be digitally developed, tested, and optimized through GeoDict simulations.

With the GeoDict software, 3D models of the materials in batteries and in PEM (Proton Exchange Membrane) fuel cells layers (GDL, MPL, CL) are digitally engineered and the decisive material properties of these models are characterized. The goal of the simulations is to optimize each of the materials to its requirements and improve the performance of the batteries or the fuel cells.

Simulate and compute parameters for the improvement and design of battery and fuel cell materials:

  • Geometrical parameters: porosity, pore size distribution, surface area, length of contact lines, tortuosity/Gurley value.
  • Conduction parameters: Thermal conductivity, thermal flux, temperature distribution, electrical conductivity, electrical flux, electrostatic potential distribution.
  • Saturation parameters: Saturation exponent, capillary pressure curve, variable contact angles.
  • Diffusion & flow parameters: Permeability, diffusivity, particle concentration, path of single particle.

GeoDict simulations address the central topics in batteries and fuel cell materials research and the resulting two-phase fluid flow properties.

The GeoDict® package for Electrochemistry

The GeoDict® Electrochemistry package has been developed for the simulation of electrochemical processes. It includes interface tools to import and segment microCT and FIB/SEM data and material modeling modules to design 3D models from user-defined specifications, along with material property predictors to analyze them.
