The ImpedanceAnalyzer is an open-source, web-based analysis platform aimed at making physics-based models as easy to use as equivalent circuits for the analysis of experimental EIS spectra.
This repository contains all of the data and code used in the first manuscript about the tool. To cite this repository:

If you are interested in using the COMSOL model to simulate the linear impedance response of the P2D battery model, you may find the following paper containing the frequency-domain equations useful:
The code in this repository has been tested with the following versions of software:
- Python 3.6.3 https://www.python.org/
- Conda 4.3.30 (through Miniconda3) https://conda.io/miniconda.html
- Git Bash on Windows
The environment.yml file can be used to recreate the same conda environment with the following commands:
conda env create -f environment.yml
source activate ImpedanceAnalyzerManuscript
COMSOL v4.4 and LiveLink for MATLAB (2013b) were used to run the impedance simulations.
