“…Full sulfation is most important reason for failure of lead-acid batteries. There some reports about reduction of sulfation in leadacid batteries [14][15][16]. Nevertheless, there is not any report for the complete preventing the sulfation in the lead-acid batteries.…”

“…Therefore, this irreversibility causes the permanent deposition of the hard crystalline phase of PbSO 4 as an inactive material on electrodes [19,25] as shown schematically in figure 2. This is generally termed as 'irreversible sulphation' which keeps on increasing with operating cycles and is a major cause of LAB failure [30,31]. Further, the rise in working temperature [32] and high depth of discharge (DOD) [33][34][35][36][37][38] are some other factors which can accelerate it.…”

Development in lead (Pb)-acid batteries (LABs) is an important area of research. The improvement in this electrochemical device is imperative as it can open several new fronts of technological advancement in different sectors like automobile, telecommunications, renewable energy, etc. Since the rapid failure of a LAB due to Pb sulphation under partial-state-of-charging, electrode grid corrosion and water loss are some major obstructions in its advancement. The doping of various carbon forms into the negative active material of an electrode has been suggested to be effective at improving the storage capacity and cyclic life of LABs by suppressing irreversible sulphation. This report is an attempt to focus on different theories related to the working mechanism of carbon and to summarize the investigation results observed by various researchers regarding the significant role of nano-carbon additives in LABs. On the basis of that, we tried to compare their performance along with the discussion on the best possible additive.

Concentrated sulfuric acid (SA) and nonionic surfactant (C 12 H 25 (OCH 2 CH 2 ) 10 OH, C 12 E 10 ) form lyotropic liquid crystalline (LLC) mesophases in a broad range of SA concentrations; the SA/C 12 E 10 mole ratio may vary from 2 to 11 in the LLC mesophases in the presence of a small amount of water. The mesophase is hexagonal at low SA concentration and cubic at higher concentrations. Three different compositions were prepared (one hexagonal and two cubic) with the SA/C 12 E 10 mole ratio of 2.5, 6, and 9, denoted as 2.5LC, 6LC, and 9LC, respectively. They all display electrochemical SA activity in Pt and Pb systems. Most interestingly, they show the electrochemical formation of stable PbO species in a deeply acidic medium as evidenced by the X-ray diffraction, cyclic voltammetry, and linear sweep voltammetry experiments. The preferable properties of PbO over PbSO 4 for lead acid batteries (LABs) make it uniquely positioned as a superior gel electrolyte for the LABs that would mitigate sulfation.
