CFD Online Discussion Forums - Data source for Echemistry Scheme File

Hello everyone!

I would like to enter data for LiFePO4 cathode in the Fluent battery model echemistry library scheme file and I know how to do it.

However I do not have the relevant data for it. I've searched high and low but couldn't find it on the web.

If anyone has managed to gather this data and doesn't mind sharing it, please help.

Specifically, I'm looking for data in the following variables:

Code:

(theoretical-capacity (constant . 986.4))

                (max-solid-li-concentration (constant . 51200))

                (density-active (constant . 5010))

                (density-filler (constant . 1800))

                (density-current-collector (constant . 2710))

                (diffusion-coefficient (constant . 1e-13))

                (electric-conductivity (constant . 10))

                (butler-volmer-parameter  (rate-constant (constant . 3e-11))

                                          (anodic-transfer-coefficient (constant . 0.5))

                                          (cathodic-transfer-coefficient (constant . 0.5))

                (filler-vof (constant . 0.2))  

                (diameter (constant . 0.00002))

                (bruggeman-tortuosity-exponent (constant . 1.5))

These are LCO cathode values and I would like to get the values for LiFePO4.

Thank you in advance!
