from chemistry to pack
Every push toward faster charging runs into the same wall eventually: it isn’t the wire, the electrode particles, or even the reaction kinetics that gives out first. It’s the electrolyte itself struggling to move enough lithium salt to where it’s needed, fast enough. That transport bottleneck has a name: concentration polarization. It’s one of the … Read more
Authors: Ionworks For several decades, the Doyle-Fuller-Newman model has been the cornerstone of computational battery modeling, design, and optimization. Since the model was developed based on an assumption of Fickian diffusion in the solid active material particles, the equilibrium state in a DFN model is an electrode of compositionally homogeneous particles. While this is appropriate … Read more
The need for modelling The primary reason why one is interested in having a model of a battery is it allows us to make informed decisions, optimise or control a battery to deliver on its intended applications. For instance, we may be interested in knowing how different material choices, electrode compositions or cell packaging, will … Read more
