A battery separator is a porous solid material that separates the anode and cathode in a battery to prevent short circuits. The pores in the solid are filled with an aqueous electrolyte solution. The porosity of the anode is € = 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: L= 1.00 mm Assuming flux of A through stagnant B, determine the flux of Nations in a sodium- ion battery in kgmol/s m’ at an operating temperature of 50 °C. CA = 5.00 kgmol/m C = 58.7 kgmol/m CA2 = 0.200 kgmol/m 42 = 54.9 kgmol/m Note: because this is a battery, we do not have to maintain charge neutrality (electrons move as current through the circuit), so you should use the diffusivity of the Nation (not the charge-neutral complex).
