Adsorption model standardisation

I’ve recently stumbled across the “Battery Parameter eXchange” BPX standard. Released on the 27th of June this year, and funded by the Faraday Institute, BPX aims to define a consistent set of physics-based equations for battery models.

This is a fantastic idea! From my own experience working with adsorption models, everyone likes to do things a little differently. That makes sharing models, parameters to those models, and comparing results a huge headache. Creating a standard for adsorption models would allow much more collaboration between research organisations and industry. It’s not only about defining a consistent set of equations and boundary conditions, but also the process of fitting the model parameters to experimental data.

If there is anyone reading this who resonates with what I've said, let’s talk. My experience is that the adsorption community seems to be more fragmented than other research fields like electrochemistry. Creating an adsorption model standard could be a really great start towards promoting data exchange and increasing trust.

I’m going to write a separate post about the similarities between modelling batteries and adsorption systems, as I believe there is a lot to learn from the electrochemical modelling community who have far more open-source projects such as PyBAMM that are constantly improving.

I’m building an adsorption process simulation tool AdSim, and if that interests you, let’s talk.
