(a) Polarization curves (Voltage (V) vs. current (I)) and (b) gross power density (Pd) as a function of current density for RED tests using multivalent ions (NaCl/MgCl2) of different molal compositions. In pure MgCl2 solution, the power density and the OCV decreased by 94% and 57%, respectively, with respect to pure NaCl solution. Reproduced with permission from [5]. Copyright 2016 Elsevier.
