Analyzing rate performance data in battery electrodes is greatly facilitated by access to simple analytical models. Here, we describe a number of simple equations for fitting capacity–rate data. These equations output fit parameters, such as the characteristic time, which quantify rate performance. This characteristic time can be linked to mechanistic effects, such as diffusion and electrical limitations, allowing quantitative analysis.
