In this study, we investigated the results based on the “C.R.M. resistance” of positive electrodes (Co-, Ni- and Mn-based materials), which was directly related to the input-output power characteristics, using the “four-electrode cell”.^1,2) By comparing the resistance of these positive electrodes, we found that the Ni-based electrode had the lowest C.R.M. resistance in the range of 4.0 V–3.5 V and the Mn-based electrode had a stationary C.R.M. resistance over a wide range of both the charge and discharge states.
