Electrical resistivity is an important measure to qualify electrodes for lithium‐ion batteries. A reliable determination of conductivity is of high practical importance with regard to, for example, electrode production improvements and quality control. To complement state‐of‐the‐art measuring techniques, a new method has been developed based on a new “micron‐powder probe”. Following a simple measuring procedure, the system allows nondestructive, highly reproducible, and rapid data acquisition. In this paper, we describe the new concept thoroughly and present experimental results. These results demonstrate that an initial determination of resistance values in battery electrodes is beneficial especially if it is combined with an electrical postmortem analysis of cycled cathode disks. The outcome of our investigation is validated with regard to the electrochemical performance of cathodes in half‐cells.
