A battery separatoris a porous solid material that separates the anode and cathode in a battery to preventshort circuits. The pores in the solid are filled with an aqueous electrolyte solution. The porosity of the anode is c = 0.47 and the tortuosity is t = 2.35 The maximum rate of charge/discharge of the battery is related to diffusion of the ions between the anodes. The system is depicted below: Assuming flux of A through stagnant B, L = 1.00 mm determine the flux of Nations in a sodium- ion battery in kgmol/smat an operating temperature of 50 °C. Note: because this is a battery, we do not Cu = 5.00 kgmol/m Si=0.200 kgmol/m have to maintain charge neutrality = 58.7 kgmol/m = 54.9 kgmol/m (electrons move as current through the circuit), so you should use the diffusivity of the Nation (not the charge-neutral complex).
