“…Moreover, lignin, a soluble polymer, improves accumulator terminal voltage and resists passivation in deep-cycle cells (Vanýsek et al, 2020). The absence of lignin, previously introduced via wooden separators, shortened cycle life due to irreversible sulfation (Pavlov, 2011).…”

“…Material-based methodologies are targeted techniques principally designed to tackle specific aging mechanisms through chemical or electrochemical means, often involving modification of the cell components' composition. Usually performed offline, these techniques frequently address multiple aging mechanisms concurrently, employing tools such as active material expanders and electrolyte additives (Bullock, 1979;Shiomi et al, 1997;Vermesan et al, 2004;Vanýsek et al, 2020;Wu et al, 2020).…”

This comprehensive review examines the enduring relevance and technological advancements in lead-acid battery (LAB) systems despite competition from lithium-ion batteries. LABs, characterized by their extensive commercial application since the 19th century, boast a high recycling rate. They are commonly used in large-scale energy storage and as backup sources in various applications. This study delves into the primary challenges facing LABs, notably their short cycle life, and the mechanisms underlying capacity decline, such as sulfation, grid corrosion, and positive active material (PAM) degradation. We present an in-depth analysis of various material-based interventions, including active material expanders, grid alloying, and electrolyte additives, designed to mitigate these aging mechanisms. These interventions include using barium sulfate and carbon additives to reduce sulfation, implementing lead-calcium-tin alloys for grid stability, and incorporating boric and phosphoric acids in electrolytes for enhanced performance. In contrast, operation-based strategies focus on optimizing battery management during operation. These include modifying charging algorithms, employing desulfation techniques, and integrating novel approaches such as reflex and electroacoustic charging. The latter, a promising technique, involves using sound waves to enhance the electrochemical processes and potentially prolong the cycle life of LABs. Initial findings suggest that electroacoustic charging could revitalize interest in LAB technology, offering a sustainable and economically viable option for renewable energy storage. The review evaluates the techno-economic implications of improved LAB cycle life, particularly in renewable energy storage. It underscores the potential of extending LAB cycle life through material and operation-based strategies, including the innovative application of electroacoustic charging, to enhance the competitiveness of LABs in the evolving energy storage market.

“…8 However, the molecular-scale interactions between PbSO 4 and barite are complex and poorly understood, especially in the sulfuric acid solutions that are relevant to lead−acid batteries. A better understanding of such processes will aid in ongoing efforts to produce improved battery additives 9,10 and build models of battery operation. 11 We hope this work will help address emerging grid-level power storage needs by facilitating the development of lead−acid batteries with improved efficiency, cycle life, and recyclability.…”

Barite (BaSO4) is a common additive in lead–acid batteries, where it acts as a nucleating agent to promote the reversible formation and dissolution of PbSO4 during battery cycling. However, little is known about the molecular-scale mechanisms that control the nucleation and cyclic evolution of PbSO4 over a battery’s lifetime. In this study, we explore the responses of a barite (001) surface to cycles of high and low lead concentrations in 100 mM sulfuric acid solution using in situ atomic force microscopy and high-resolution X-ray reflectivity. We find that PbSO4 epitaxial films readily nucleate on the barite surface, even from solutions that are undersaturated relative to bulk PbSO4. Despite this, barite (001) proves to be an ineffective nucleator of bulk PbSO4, as multilayer growth is suppressed even in highly supersaturated solutions. Instead, we find evidence that Pb2+ ions can directly exchange with Ba2+ to create mixed (Ba,Pb)SO4 surfaces. These chemically mixed surfaces do not host PbSO4 monolayers as readily as pristine barite, and the original reactivity is not regained until a fresh surface is re-established by aggressive etching. Our results can be partly explained by traditional models of thin-film growth, which predict a Stranski–Krastanov (S–K) growth mode, where monolayer films are stabilized by a reduction in surface energy, but multilayer growth is inhibited by epitaxial strain. Complementary density functional theory calculations confirm the basic energetic terms of the model but also show evidence for thickness-dependent energetics that are more complex than would be predicted from traditional models. The experimental results are better understood by extending the model to consider the formation of mixed surfaces and films, which have reduced strain and interfacial energies relative to pure films while also being stabilized by entropy of mixing. These insights into nonstoichiometric heteroepitaxy will enable better predictions of how barite affects PbSO4 nucleation in battery environments.
