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?
It is significantly faster than its competitors for single cell (anode/cathode pair) simulations.
It comes with a library of common electrode parameters and chemistries.
Simulations can be run for free via this website, meaning that no installation is required.
It is able to cope with larger systems of equations than its competitors (it exhibits linear scaling).
These features mean that computations can be run that are not possible using other software. We have the computational power to solve the 10s of millions of equations that are required to accurately model thermally coupled models of realistic device such as pouch cells. These large computations can be solved in modest compute time (often <30 minutes) on a standard desktop computer.
Nonlinear diffusivity in the solid, and in the electrolyte enables accurate simulation of real devices.
Full thermo-electrochemical coupling.
The ability to solve in the 3-dimensional geometries required for pouch cells and battery modules.
Linear scalability and ability to solve systems of ~100,000,000 (and even more, depending on the machine's RAM) Differential Algebraic Equations (DAEs).
Accurate reproduction of real experimental data including drive cycles, not just discharge curves.
Several predefined, commercially relevant parametrisations (Kokam 7.5Ah pouch cell, LG M50 5Ah, 21700 NCA/Gr-Si 4.5Ah).
A library of material properties so that users can design their own cells.
Users can define their own parameters sets allowing highly customizable numerical experiments.
