Electronic conductivity for electrodes with 2.5 and 5 wt% C45 carbon black and surrogate active particles (Al₂O₃) made using (A) increasing bath temperature and (B) increasing bath pH. Error bars are found from the 5 µm uncertainty in electrode thickness which determines how conductivity is calculated using a four-point probe. (C) Electronic conductivity for electrodes made at 85 °C using an alkaline bath.
