This 1D model example demonstrates how to use the Events interface in conjunction with a battery cell model to simulate battery capacity loss during cycling. The battery is switched between constant voltage and constant current operation, both during charge and discharge. Cycleable lithium is lost in the negative electrode due to a parasitic lithium/solvent reduction reaction.
This example focuses on the species transport within the gas diffusion layers (GDLs) of a proton exchange membrane (PEM) fuel cell. The geometry models a cell with two adjacent flow channels of different pressures, a situation that may occur in a cell with serpentine flow channels, or in a cell using an interdigitated flow field design. The model uses current balances, mass transport equations ...
This model demonstrates the Lithium-Ion Battery interface for studying the discharge and charge of a lithium-ion battery for a given set of material properties. The geometry is in one dimension and the model is isothermal. Battery developers can use the model to investigate the influence of various design parameters such as the choice of materials, dimensions, and the particle size distribution ...
This example simulates the heat profile in an air-cooled cylindrical battery in 3d. The battery is placed in a matrix in a battery pack. The thermal model is coupled to a 1d-battery model that is used to generate a heat source in the active battery material. The model requires the Batteries & Fuel Cells Module and the Heat Transfer Module
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.
This model simulates a temperature profile in a number of cells and cooling fins in a liquid-cooled battery pack. The model solves in 3D and for an operational point during a load cycle. A full 1D electrochemical model for the lithium battery calculates the average heat source.
This tutorial example models the currents and the concentration of dissolved metal ions in a battery (corrosion cell) made from an orange and two metal nails. This type of battery is commonly used in chemistry lessons. Instead of an orange, lemons or potatoes can also be used.
This model example simulates an air-cooled cylindrical 18650 lithium-ion battery during a charge-discharge cycle, followed by a relaxing period. A one-dimensional cell model is used to model the battery cell chemistry, and a two-dimensional axi-symmetrical model is used to model the temperature in the battery.
This model example investigates the transport of reactants and water in a high temperature PEMFC. The model includes mass and momentum transport phenomena in the flow channels, gas diffusion layers (GDLs), and porous electrodes, as well as electrochemical currents in the GDLs, the porous electrodes, and the polymer membrane.
This example shows how to use the Tertiary Current Distribution interface to model the currents and electrolyte mass transport in a thin-film all-solid-state lithium-ion battery. A separate Transport of Diluted Species interface is coupled to the electrochemical reactions to model the mass transport of lithium in the positive electrode. Various discharge currents are studied, and the different ...
