1D Lithium Air battery Simulation in COMSOL Multiphysics

Welcome to this course!
This course is on 1D Lithium-Ion Battery Multiphysics Simulations.

In this course, you will learn advanced Lithium Battery Simulations using multiple Physics interfaces. This course will explain how to actually work with complicated simulations such as a battery.
If you are totally new, I would suggest first complete our course on “Learn COMSOL Multiphysics simulation: Basics to Advanced”as this is a bit advanced course, even though I tried to explain it as easy as possible.

  Lithium-ion batteries have become the most common rechargeable batteries for consumer electronics and automotive applications due to their high energy densities, decent power density, relatively high cell voltages, and low weight-to-volume ratios.
  Brief feature of this course:

• 1D simulation of Complex Lithium-Ion battery Simulation.

• The files and parameter values so that you can watch and prepare your own model.

• Basic understanding of how to actually do simulations.

• HIGH-QUALITY lectures

  Battery Simulation is a demanding topic in Energy Storage and Next Generation Energy Demand. Rechargeable lithium-air batteries have recently attracted great interest mainly due to their high energy density. A unit cell of a lithium-air battery typically consists of a thin lithium sheet as the negative electrode, a porous carbon electrode filled with oxygen/air as the positive electrode, and a separator material between the electrodes. The organic electrolyte used consists of a dissolved lithium salt in an aprotic solvent. The oxidation of lithium at the anode and reduction of oxygen at the cathode induces a current flow.
  In this battery simulation course, the discharge of a lithium-air battery is simulated using the Lithium-Ion Battery interface. The transport of oxygen (from external air) in the porous carbon electrode is modelled using the Transport of Diluted Species in Porous Media interface in COMSOL Multiphysics. The electrochemical reaction of oxygen reduction in the carbon electrode leads to changes in the concentration of the reaction product and electrode porosity. In this example, model analysis is done for a range of discharge current densities. A comparison of the oxygen concentration, porosity, and film thickness in the positive electrode at low and high discharge current densities is done to understand their effect on the cell voltage profiles. This model can be used for studying the performance of lithium-air batteries and for providing insights toward cell design.

  Note that this is a very specific simulation course which is good to get an idea of how battery simulation is actually done. Consider this as a starting point in the simulation of batteries. After trying out the 1D simulation, you can try out how you can implement the same idea in 2D and 3D. The course is prepared with the help of the Official COMSOL simulation model and documentations.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
