Hey, I'm working right now in some battery characterization and I recently ran a charge/discharge test on a LIR2032 coin cell battery. I'm getting this graph (purple and blue with square signal) but It really doesn't look like a galvanostatic curve so I was hoping you could help me figuring it out how to get one because all of the parameters of the test seem fine for me. For this I'm using a SMU that sources voltage and measures current and I'm also using a RC circuit but instead of the capacitor I have my coin battery. Any help would be very useful, thanks!
