This example replicates the results of the Jelly Roll tutorial example using a flattened representation of the wound spiral-based geometry. See that model entry for details on the background, original geometry, materials, and the general physics setup. Mapping the original problem to a ... En savoir plus
This app can be used as a design tool to develop an optimized battery configuration for a specific application. The application computes the capacity, energy efficiency, heat generation, and capacity losses due to parasitic reactions of a battery for a specific load cycle. Various ... En savoir plus
Voltammetry is modeled at a microelectrode of 10um radius. In this common analytical electrochemistry technique, the potential at a working electrode is swept up and down and the current is recorded. The current-voltage waveform ("voltammogram") gives information about the reactivity and ... En savoir plus
Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative ... En savoir plus
These two apps can be run to set up a digital twin of an electric scooter battery. The Digital Twin Simulator of an Electric Scooter Battery (the "simulator" app) simulates the use of an electric scooter and generates battery current and voltage data over time. The Digital Twin ... En savoir plus
This example demonstrates the Lithium-Ion Battery, Single-Ion Conductor interface for studying the discharge of a lithium-ion battery with solid electrolyte. The geometry is in one dimension and the model is isothermal. The behavior at various discharge currents and solid electrolyte ... En savoir plus
The following example is a 2D tutorial model of a lithium-ion battery. The cell geometry is not based on a real application; it is only meant to demonstrate a 2D model setup. En savoir plus
A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model ... En savoir plus
During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... En savoir plus
This model reproduces the NiCd battery model and the results presented in De Vidts' and White's paper from 1995. Ref: P. De Vidts, R. E. White, “Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode”, J. Electrochem. Soc, Vol. 142, No. 5, May 1995. En savoir plus
