Abstract

For decades authors have preferred to model batteries with either Thevenin-style models using RLC, or Randlesstyle by adding a Warburg element. These are claimed to model accurately. We present convincing empirical evidence suggesting that a fractional-derivative (constant-phase element) model is required. Our data shows that existing state-of-the-art models may be overly complicated, requiring numerical rather than physical considerations to find parameters.
