Batteries with different chemistries and designs encounter various (redox reactions) to store energy through applying charges and discharges rates. Redox flow batteries systems such as zinc bromine batteries cells systems (ZnBr2) can be enclosed with high surface area anode electrodes (reactors) and charged with some amount of added carbon particles for zinc deposition. The electrochemical reactions within a fabricated ZnBr2 battery cell system have been investigated with the coupled inlets and outlets brass fitting materials (15mm and 30mm) of different anode and cathode electrolyte compositions. SEM analysis was explored on some charged particles collected from the anode reactor to identify all the existing elements within the deposited charged zinc particles after several charges. The investigated zinc particles were between 254 microns to 354 microns. The electrolyte composition includes 3 moles of KBr (535.51 grams), 1 mole of KCl (111.89 grams) as the cathode side electrolyte and 3 moles of ZnBr2 (649 grams), 1 mole of ZnCl2 (205 grams), and 1M of KCl (111.826 grams) as the anode electrolyte solution. Originally, this journal paper has discovered the importance of coupling chemically resistance materials to ZnBr2 cells as investigated on the fabricated ZnBr2 cell that was initially converted to a CuZn2 battery cell system and reverted to the ideal ZnBr2 cell system before using an SEM technique to identify separately the present elements.
