II Pb-PbF2 cell and LaSrMnO4II sintered La0.9Ba0.1F2.9 II Pb-PbF2 cell. Figure shows the first five cycles between -0.8 V and 0.8 V with different scan rates (0.05 mV/s, 0.08 mV/s, 0.1 mV/s, 0.12 mV/s) at 170 °C and 140 °C. These slow scan rates were selected to study diffusioncontrolled reactions at different temperatures. Figure The CV measurement conducted at 170 °C (Figure ) reveals an oxidation peak at 0.16 V when using a scan rate of 0.05 mV/s.
