Ultra-Fast Online Solution to the Newman Model of Li-Ion Battery Performance

Welcome to DandeLiion

These web pages provide general information on the DandeLiion solver for lithium-ion batteries. It also allows you to submit simulations which will be carried out on our server for free; the results can be viewed in the browser of downloaded for detailed post-processing. Suggestions and contributions are welcome! Feel free to contact us.

What is DandeLiion?

DandeLiion is an ultra-fast solver for electrochemical models of planar lithium-ion cells and thermal-electrochemical models of three-dimensional composite pouch cells. It solves models of the form first described by Doyle, Fuller, and Newman in the mid 90s, and which are now commonly known either as Newman models, or as porous electrode theory.

Why use DandeLiion?

3D simulation examples

Contact the DandeLiion team for more information.

Pouch cell heating during 5C discharge. A fully coupled thermo-electrochemical 3D simulation (9600 coupled DFN models).
Tesla Model S battery module simulation (1C discharge, temperature distribution across the module). A fully coupled thermo-electrochemical 3D simulation with liquid cooling (440 coupled DFN models).



Temperature coupling

Temperature distribution in a 3-D pouch cell. The full DFN model is solved in each finite volume. This simulation involves solving more than 5M coupled differential-algebraic equations.

Drive Cycle simulation

A 1/2 hour fragment of a drive cycle simulation (red line) in comparison with experiment (black line). The relative error (orange line) does not exceed 1%.

Charge/discharge experiment simulation

LG M50 battery simulation with a time-varying current demand.

Commercial NCA/Gr-Si battery discharge 

High-energy 21700 NCA/Gr-Si battery simulation. Discharge at two different temperatures and comparison with experiment.

High-current Drive Cycle simulation

An example of a high-current drive cycle simulation with a highly a non-uniform current profile. Peak charge and discharge currents reach 10C.

Secondary variables

A constant-current (1C) charge and discharge profile of a commercial Kokam (7.5 Ah) pouch cell. Both micro- and macroscopic variables (such as concentration of Li ions in particles, potentials, etc.) at user-defined times can be saved to a set of files and post-processed offline.

GITT experiment simulation

21700 NCA/Gr-Si battery undergoing a Galvanostatic Intermittent Titration Technique (GITT) experiment. Experimental current and voltages vs simulation with excellent agreement.

GITT simulation (zoomed-in)

A zoomed-in picture of the comparison with the experiment demonstrating the quality of the comparison.
