Exploring electrochemical lithium-ion battery degradation modelling.
At the end of August 2020 my OG Pixel of 3 years stopped turning on. I became curious in understanding what was happening to the battery that final lead to the retirement of one of my favourite phones. I began looking into battery simulation textbooks, videos and papers (all will be referenced below). Common mathamatical models include equivalent circuit modeling (ECM), black-box modeling and fundamental governing equations. I plan to first focus on a blend of empirical data and fundamental governing equations (electrochemical models) by using this paper as a starting point and then seeing where this research dive will take me next.

I am still looking for a opensource battery database that is more current. The battery data I'll be using for now is from the NASA Ames Prognostics Center of Excellence (PCoE) testbed. The README document with this data is under battery-data-README.txt.
