This model demonstrates the impact of convection and diffusion on the transport-limited electrodeposition of a copper microconnector bump (metal post). Microconnector bumps are used in various types of electronic applications for interconnecting components, for instance liquid crystal ... En savoir plus
A catalyst particle with a hypothetical microstructure is described in detail. The heterogeneous description is approximated in a second model with a homogeneous particle and the results from the two approaches are compared. See: https://www.comsol.se/blogs/modeling-approaches-in ... En savoir plus
This example studies the kinetics of the neutralization of chlorine gas in water solution. The model assumes that the fluid volume is perfectly mixed and constant. This means that the chlorine has dissolved to an almost saturated state (1·10-2 mol/m3) and that the hydroxide has also ... En savoir plus
This tutorial example illustrates the versatility of the Reaction Engineering interface. The hydrogen iodine reaction is modeled in a batch reactor with constant volume. Both isothermal and non-isothermal conditions are modeled. En savoir plus
Lithium iron phosphate (LFP) is a common positive electrode material in lithium-ion batteries. Specific for the LFP electrode material is that its equilibrium (open circuit) potential, when defined as a function of the lithiation state, features a large flat plateau with a more or less ...

The copper current collector on negative graphite electrodes in lithium-ion batteries have been seen to dissolve at over discharge. This can be a safety concern as the dissolution damages the current collector irreversibly and dissolved copper ions can redeposit and form dendrites. ... En savoir plus
This example shows how to model secondary current distribution and electrode growth with a moving geometry. To avoid numerical instabilities, a seed layer is introduced in the initial geometry to obtain a right angle at the edge between the growing electrode and the insulator. En savoir plus
The purpose of this model is to visualize the electric potential in an electrochemical cell, for example a battery. This is done at OCV and during operation. In a battery, this would correspond to OCV, discharge, and recharge. The potential profile is explained both for cells with planar ... En savoir plus
Oscillating chemical reactions were long thought to simply not exist in homogeneous solution, and even the poster child, the Belousov–Zhabotinsky reaction, met such an initial skepticism, that even though it was discovered in 1951, it took almost 20 years for it to gain widespread fame. ...

This example models the temperature profile in a liquid-cooled prismatic battery pack during a high-rate charge. The pack consists of 16 prismatic battery cells connected by busbars, placed on an aluminum plate containing four cooling channels. The battery pack is assumed to have two ... En savoir plus
