We have investigated the influence of mixing conditions during the positive electrode fabrication on the discharge performance and internal resistances under high rate discharge of a test lithium-ion battery at 30 °C, employing fast Fourier transform electrochemical impedance spectroscopy in-situ to minimize the change in the state of charge. The internal resistances are assigned to each component in the positive electrode by comparing with cross-sectional scanning electron micrographs. The mixings of the active material and conductive filler with too low rotating speed both before and after the addition of the binder and solvent, pre-mixing and slurry mixing, respectively, give smaller active contact area between agglomerated conductive filler and the active material, leading to larger interfacial resistance. The pre-mixing and slurry mixing under too high rotating speed both result in larger interfacial resistances due to poor contacts of agglomerated active material with the conductive filler and the electrolyte.
