“…Basically, the discharge of the Mg/DCIA organic cell is governed by the following electrochemical reactions 2Mg --~ 2Mg'-" + 4e (Anodic reaction) [1] Standardization of cathode mix by varying amount of acetylene black.--Organic depolarizers are well known for their relatively low conductivity and, since the heterogeneous electrode processes take place primarily at the surface, more quantity of the supplementary conducting materials which occupy critically needed space and contribute nothing coulomctrically, is typically required for organic cathode mixes. Similarly, the DCIA organic compound cannot draw the desired electrons during reduction and hence could give rise to the sloping discharge profile and negligibly small capacity ( Fig.…”

In a search for new pollution-free materials for energy delivery devices, we found that the use of dichloroisocyanuric acid (DCIA) when coupled with magnesium in an aqueous medium of magnesium perchlorate gives rise to the possibility of a 2.4 V output battery. The current density obtained is up to 17 mA cm -'. An optimum amount (50%) of acetylene black has been added to the DCIA cathode mix to assure a relatively high degree of electronic conductivity and utilization efficiency. Several battery parameters such as capacity, energy density, coulombic efficiency, and internal resistance were evaluated at various current densities ranging from 0.83 to 16.67 mA cm z. At a typical discharge rate of 0.83 mA cm -z we report the capacity, energy density, and the coulombic efficiency to be 200 Ah (kg of DCIA) ~, 432 Wh (kg of DCIA) ~ and 48%, respectively. The discharge data are fitted to a general standard model as proposed for primary cells and a good correlation has been found with the experimental results. Surface morphologies of magnesium anodes discharged at different current densities were evaluated using scanning electron microscopy (SEM) for supplementing the observed electrochemical data. High voltage, high melting point, high energy density, and nontoxicity are the most striking features of the reported system which, in our opinion, has the potential to replace the conventional primary battery systems. o~ , , I I J I I J J I -r -~ 0 25 SO 75 9 TIME /rain 67 ~ 12 50 cn~l L J , I J , , l J a 25 50 75 ) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.

“…These black liquors are titrated by dilute sulphuric acid to ad just the pH values. Glicksman and Morehouse (1958) had investigated the pH effect on the electrode potential of aromatic nitro compounds (such äs 2,4-dinitroaniline and 2,4-dinitrotoluene). It was seen that the cathodic Potentials of the nitro compounds increase äs the pH of the electrolyte is decreased, a result which is in agreement with theory and with the present measurements äs shown in Figs.…”

The delignification process during preparation of unbleached soda pulps from bagasse pith in presence of some nitrogen containing additives is enhanced in the following Order: hydroxylamine hydrochloride > p-nitrobenzoic acid > m-nitrobenzoic acid. Study of ultraviolet and infrared abso tion spectra of soda bagasse pith lignin, also potentiometric titration of the black liquors confirm this observation. Moreover, the effect of the additives on the rate of delignification is in agreement with this result.

“…Of late, organic nitro compounds of metal-organic cell systems have received attention as attractive cathodes owing to their flat discharge voltage and high theoretical energy density [1][2][3][4]. Further, these compounds undergo reduction involving 2-12 electron transfer reactions when compared to 1 or 2 electron transfers with inorganic cathode materials such as MnO 2 , HgO, CuO, PbO 2 , AgO, NiO 2 , etc.…”

Electrochemical characteristics of m-dinitrobenzene (m-DNB) based composite cathode materials involving compounds such as AgCl, TiO 2 , HgO and CuCl have been investigated and (Mg AZ31 alloy anode) as an activated battery system using 2 M magnesium perchlorate aqueous electrolyte. The concentration of the composites has been optimized so as to obtain high electrochemical performance of Mg/m-DNB reserve batteries through constant current discharge studies. Mg/m-DNB cells containing 5-wt % of HgO when discharged at current density of 2.1 mA cm )2 delivered 5.3 Ah capacity corresponds to a columbic efficiency of 97% as compared to the cells without composite.
