Learning the Electrochemistry of Degradation and Safety in Graphite Porous Electrodes for Lithium-ion Batteries
… and cost requirements. However, modeling battery degradation is challenging as it not only is hard to visualize in-operando, but also affects cell performance at multiple scales - from single particle to porous electrode to the battery pack. Insights obtained from experimentation on a given scale …
