Summary:SDX® which is surface coated aluminum current collector (AL) with carbon black and organic binder, makes a cell resistance lower and adhesion between cathode active material and AL stronger, so as to improve battery performances dramatically. The cell resistance was separated simply into electronic resistance and ionic resistance. We successfully separated the electronic resistance into material resistance and interface resistance between cathode active material and AL. And then, we independently measured the material resistance and the interface resistance by Electrode Resistance Meter (HIOKI E.E. CORPORATION) which can separate electrode resistance into material and interface resistance. In this paper, more detailed examinations were carried out, and the mechanism of decreasing resistance by SDX® in lithium ion battery (LIB) was tried to be clarified.
