“…267 The passivation effect relates to the interference of charges uptake through blocking the HER active sites; this can be rationalized by decreasing the doublelayer capacitance to suppress water splitting. 269,270 On the other hand, heed must be paid to the interactions between the additives and the electrode surface. In one model proposed, during the operation (discharge) of lead−acid batteries, the Pb surface of the Pb−Sb alloy anode is positively polarized, preferring to electrostatically absorb SO 4 2− ; on the other hand, the Sb surface is negatively charged, thus being preferentially covered by H + .…”

“…For instance, adding 10 –4 M 2-methoxybenzaldehyde into the 4.5 M H 2 SO 4 aqueous electrolyte downshifts the HER onset potential of the Pb–Sb alloy anode from −0.574 V to −0.674 V vs SHE, where the onset current density is set as 0.1 mA cm –2 (Figure a) . The passivation effect relates to the interference of charges uptake through blocking the HER active sites; this can be rationalized by decreasing the double-layer capacitance to suppress water splitting. , …”

Aqueous electrolytes are the leading candidate to meet the surging demand for safe and low-cost storage batteries. Aqueous electrolytes facilitate more sustainable battery technologies due to the attributes of being nonflammable, environmentally benign, and cost effective. Yet, water’s narrow electrochemical stability window remains the primary bottleneck for the development of high-energy aqueous batteries with long cycle life and infallible safety. Water’s electrolysis leads to either hydrogen evolution reaction (HER) or oxygen evolution reaction (OER), which causes a series of dire consequences, including poor Coulombic efficiency, short device longevity, and safety issues. These are often showstoppers of a new aqueous battery technology besides the low energy density. Prolific progress has been made in the understanding of HER and OER from both catalysis and battery fields. Unfortunately, a systematic review on these advances from a battery chemistry standpoint is lacking. This review provides in-depth discussions on the mechanisms of water electrolysis on electrodes, where we summarize the critical influencing factors applicable for a broad spectrum of aqueous battery systems. Recent progress and existing challenges on suppressing water electrolysis are discussed, and our perspectives on the future development of this field are provided.

“…Therefore the inhibition of hydrogen evolution during the charging of a lead-acid battery is an important part of the engineering for any battery system. [7][8][9][10] The aim of this work is to explore the use of L-serine to inhibit the hydrogen evolution during the reaction of Pb with 5.0 M H 2 SO 4 .…”

“…There is also a lack of data on the study of lignins incorporated in the actual NAM. As a matter of fact, in most of the research works reported (3,4,5) , the surface of a solid lead electrode is used as the working electrode while the lignin is dissolved in the electrolyte (usually sulfuric acid). It is therefore of practical interest to have a method for direct evaluation of a formed NAM with a particular OE in its formulation.…”

The use of additives in the formulation of the active material of the negative plate (NAM) of lead-acid batteries has proven to be fundamental for their adequate performance and extended life-time. This research work presents a new methodology for evaluating additive effects using carbon paste composite electrodes. The performance of the composite electrodes was evaluated through cyclic voltammetry and chronopotentiometry. A protocol for the construction and evaluation of the NAM carbon paste electrodes was developed, which could be use to compare different commercial additives. The size of the working electrodes prepared in this work reduces in an important manner the evaluation time of such materials, opening the opportunity to perform testing and selection of additives in times which are much more in accordance to industry requirements.
