The RM2610 isolates and quantifies the resistance characteristics of electrode sheets, a major component of lithium-ion batteries (LIBs), as two components: the composite layer resistance and the interface resistance between the composite layer and collector. The system allows users to visualize these two quantities by measuring the surface of the electrode sheet with a test fixture that consists of an array of test probes and then using proprietary analytical techniques to quantify them.
