First, these materials have been coupled with magnesium in the presence of aqueous medium of magnesium perchlorate electrolyte. Secondly, on the consideration of, cost, magnesium anodes have been replaced with zinc and zinc/<i style="mso-bidi-font-style:normal">N</i>-halogen organic cells were also constructed using the aqueous ammonium chloride;-zinc chloride solutions. In both the cases, the metal/<i style="mso-bidi-font-style:normal">N</i>-halogen organic cells ascribe to, (a) High open circuit potential (up to 1 V vs Ag/AgCl), (b) High open circuit voltage (up to, 2.67 V), (c) High closed circuit voltage (up to 2.45 V) and (c) High energy density (up to 798 Wh kg^-1 of the organic. compound). High melting point of these cathodic materials and their non-toxic properties would supplement the scope of their commercial viability for high temperature applications as well, befitting the environmental requirements.</span>
