In the performance of lithium-ion batteries, thermal management is an important element to consider. Through modeling and simulation, you can improve the design process by analyzing how heat is transferred within the energy source.

Polymer electrolyte membrane or proton exchange membrane (PEM) fuel cells provide a potentially clean and portable source of power. This is of major interest to the transport industry as well as for power generation at fixed sites. COMSOL Multiphysics is a powerful simulation tool you can use to help understand and overcome PEM fuel cell design and construction challenges.

When designing electrochemical cells, we consider the three classes of current distribution in the electrolyte and electrodes: primary, secondary, and tertiary. We recently introduced the essential theory of current distribution. Here, we illustrate the different current distributions with a wire electrode example to help you choose between the current distribution interfaces in COMSOL Multiphysics for your electrochemical cell simulation.

In electrochemical cell design, you need to consider three current distribution classes in the electrolyte and electrodes. These are called primary, secondary, and tertiary, and refer to different approximations that apply depending on the relative significance of solution resistance, finite electrode kinetics, and mass transport. Here, we provide a general introduction to the concept of current distribution and discuss the topic from a theoretical stand-point.

During my time as a PhD student, a blue “Chemical Landmark” plaque was fitted to the building a couple of hundred yards down the road from my lab. The plaque commemorates the achievements of the researchers who made the lithium-ion (Li-ion) battery viable. Whether or not you know about the electrochemistry of rechargeable lithium-ion batteries, you probably rely on one. We carry them around in our phones and laptops, and ride in cars and planes that use them for power. […]

Did your chemistry teacher use an orange or lemon to demonstrate the concept of a battery, back in the day? You might remember how she magically produced electricity by sticking a couple of metal nails into the citrus fruit, as the whole class watched in awe. What if we now used simulation tools to demonstrate how an orange battery works, and then use that as an intro to electrochemistry modeling?

On Friday I wrote about designing safer lithium-ion batteries, and showed you a few resources for helping people do just that. Now I’d like to show you a lithium-ion battery model and briefly run through how it can be created in COMSOL Multiphysics in three sequential studies.

Unless you live under a rock, you’ll have heard lithium-ion batteries mentioned a lot lately. Last week in Boston, a lithium-ion battery caught fire in the new Boeing 787 Dreamliner, forcing them to ground all Dreamliner planes until further notice. This type of battery makes it possible to pack lots of power into a small package. What can be done to make it operate safely?

It has always been the flexibility of COMSOL Multiphysics that attracted people from the fuel cell and battery industries. The other software back in the day did not adequately support the ability to model the electrochemical equations that were required to properly describe the behavior of their appliances. As we noticed that more and more of these vendors were interested in COMSOL Multiphysics, this led to a great increase in COMSOL’s knowledge and ability to model these applications. For example, […]

Previously, I wrote a blog post about Fiat using modeling to simulate the cooling of their lithium-ion battery packs. This got me wondering how lithium-ion batteries actually get hot in the first place.
