Description
Scope
This record contains workflows to extract feactures from the GITT (without intermittent EIS) measurement on the harvested negative electrode (anode) of the INR18650-MJ1 Li-ion battery cell from LG CHEM. It simulteaneously sets up the simulator and EP-BOLFI optimizer inputs for later parameterization.
