Electrochemical characterizations of Zn eutectic mixture | [Fe(phen)3](BF4)2 and Zn eutectic mixture | LiI cells. (a) Charge/discharge profiles of Zn eutectic mixture | [Fe(phen)3](BF4)2 cell assembled from 5 M Zinc eutectic mixture as anolyte and 0.2 M [Fe(phen)3](BF4)2 and 0.8 M LiTFSI in EC/DMC as catholyte. The volume ratio of the anolyte and catholyte is 1:2; (b) corresponding charge/discharge capacity, Coulombic efficiency (CE) and energy efficiency (EE). The normalized capacity stands for the value of the actual capacity divided by the maximum capacity under such a cell configuration; (c) charge/discharge profiles of Zn eutectic mixture | LiI cell assembled using 6.25 M Zinc eutectic mixture as anolyte and 3 M LiI aqueous solution as catholyte with a volume ratio of 1:2. The capacity is calculated based on the volume of the Zinc eutectic mixture.
