How i chose LiFeP04 as active material , and why there is no option of editing Current collectors thickness?
Actually the type of Li-ion battery, to be more specific, the electrode material will affect the simulation in two ways:
Regarding to the current collectors, usually they are tabs connecting with the electrodes/electrolyte so you can explicitly draw them in the mesh and set the material of them to be passive zones. Thanks.
I wonder which model you were using currently? Is it MSMD battery module or the li-ion battery model included in the potential model? Thanks.
Hello and thank you ,
I tried to use the MSMD , however i did not find any option about specifying properties such as current collector’s thickness, and even more basic such as selecting the cathode and anode material (LFP,LCO..etc and graphite ) ..Does this means that the material of the battery is fixed ? If not, how do i define these properties ?
Thank you for your reply. If you are using MSMD with NGTK or ECM for echem sub-models, there is actually no need for the electrodes properties as anode or cathode are not dsitinguished in the model. The whole battery cell is treated as same material. If you are using Neumann P2D model, the properties are set in the battery model panel, as shown:
Here the anode and cathode properties are set separately. For more details, please read our Theory Guide and User Guide:
For MSMD model, the echems are solved by echem sub-models, which are not deployed on the CFD mesh. The echem sub-models are connected with the CFD calculation only with the j_chem and q_chem, as described in the theory guide so that the material properties are not required for the CFD calculation. Thanks.
Ok about this, but still it is not clarified what's the type of my battery model ... Lithium Cobalt Oxide? Lithium Iron Phospate or something else, what's the dimension of my current collectors ? .. these properties are essential for my results and i dont have a clue about them in Ansys
Thank you very much !!!
