Description
Summary:1-Nitronaphthalene has been investigated for use as a battery depolarizer in conjunction with a high-energt magnesium anode. Acetylene black is added to improve the conductivity of the non-conducting organic compound and its concentration in the mix is optimized for better performance of the cathode. To assess its suitability and its characteristics as a cathode active material, magnesium/1-nitronaphthalene cells are fabricated and discharged in different electrolytes (magnesium chloride, magnesium bromide and magnesium perchlorate) at various current densities. The capacity delivered by the cell system shows better reduction efficiency of the 1-nitronaphthalene depolarizer. Cyclic voltammetric studies are carried out on a glassy-carbon electrode to understand the reduction behaviour of 1-nitronaphthalene.
