The physical parameters of the negative and positive electrode are very similar, the positive electrode had slightly lower thickness, at 76 µm rather than 84 µm, a higher pore volume of 33,5% compared to 25% and a slightly lower mean particle radius of 5.2 µm rather than 5.9 µm. Whereas the thermal properties are also very similar with the Specific hear capacity (Cp) at 990 and 950 J kg -1 K -1 respectively, thermal diffusivity, ( α) is 0.282 compared to 2.266 mm 2 s -1 and the thermal conductivity 0.892 compared to 4.058 for the dry electrodes at room temperature, which corresponds to the difference in electronic conductivity of 0.847 and 215 Sm -1 . Indicating that the thermal and electronic conductivities can be linked.
