The graph to the right is a representative graph of the full experiment using a FeCl/LiCl nanocomposite cell provided by our sponsor. During this 3 hour experiment, our MATLAB code continuously checked for the material to reach equilibrium throughout the experiment. With our implementation of the MATLAB code, the sponsor is now able to see all impedance spectra graphs produced from a single experiment in one graph.
FeCl/LiC nanocomposite material’s change of impedance in 3 hours
Example of variance of reversible nanomaterial cell
The table below summarizes the variance value for each set of impedance spectra for the reversible cell (FeCl/LiC). The number of graphs to compare for variance was set to 5 with the point of interest being 32 (63.3 Hz). The graph shown on the left are representative of the first 5 graphs of the experiment with the points of interest colored in red. The total number of graphs at the end of the experiment was 20 graphs meaning there were 4 sets of variance.
The graph on the right is an example of MATLAB comparing the error between an experimental spectra to a target spectra. This will be done using Least Squared Error analysis with the data normalized to get a metric that allows us to see how close our data is to the target spectra.
Experimental Data vs. Target Data for Copper Sulfate
Imaginary vs. Real Axis for Copper Sulfate Impedance at 100 Hz frequency
The graph on the left produced by MATLAB shows the impedance spectra of a copper sulfate composite at a 100 Hz frequency. The team carefully chose to analyze the impedance spectra at a single frequency of a 100 Hz which is the middle of the range of frequencies used to observe impedance.
