“…But under HRPSoC conditions, where a LAB delivers high-discharge current and gets a short duration of charge only, these reverse electrochemical reactions usually get hindered [23][24][25][26][27] mainly due to (i) Recrystallization of amorphous PbSO 4 particles generated during the discharge process into rigid crystalline form (usually large in size >10 μm [28]) which are hard to be reduced because of its low specific surface area (SSA) or porosity [7]. (ii) The non-conducting nature of the so-formed PbSO 4 crystals hinders the reaction process [8,9,18,29].…”

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.
