Button batteries have a high output-to-mass ratio; lithium–iodine batteries consist of a solid electrolyte; the nickel–cadmium (NiCad) battery is rechargeable; and the lead–acid battery, which is also rechargeable, does not require the electrodes to be in separate compartments. A fuel cell requires an external supply of reactants as the products of the reaction are continuously

This study aimed to optimize the recovery of transesterifiable oil from industrial fats, oil, and grease (FOG) esterified with an H2SO4 catalyst extracted from discarded lead-acid batteries. In recovering the oil, a thermal process was employed to extract it from the raw FOG, followed by esterification with sulfuric acid derived from lead-acid batteries. Central composite
In this paper, we report on a novel ceria-supported platinum catalyst prepared by a rapid solution-combustion reaction and its effectiveness in realizing a sealed lead-acid battery with nearly 100% recombination of hydrogen and oxygen gases, generated during its recharge, into water.

Gas-recombining catalysts have been used for many years in some lead−acid batteries, as well as in other battery systems, to recombine hydrogen gas with oxygen and produce water vapour, which condenses and reduces the need for water additions. In VRLA batteries, water replenishment occurs by virtue of the reaction of oxygen with the negative
One of the most efficacious and affordable tactics to remove the barriers faced with lead-acid batteries is addition of a low dosage of additive (s) into their electrolyte [9, [22], [23], [24]]. The compounds selected as additive should be non-toxic and non-hazardous.

Lead-acid battery consists of more than 50% of the secondary battery market, and the lead source for lead-acid battery production mainly comes from a nearly equal proportion of lead and lead resources. Primarily, lead resource is chiefly in the form of minerals, such as PbCO 3, PbS, and PbSO 4 [257, 258]. The other secondary lead resource emerges mostly from spent lead

Implementation of battery management systems, a key component of every LIB system, could improve lead–acid battery operation, efficiency, and cycle life. Perhaps the best prospect for the unutilized potential of lead–acid batteries is electric grid storage, for which the future market is estimated to be on the order of trillions of dollars.
In terms of catalysis used in secondary batteries, the first things we could think of are Li-S and Li-O 2 batteries. As for the LSB, (19−22) it is consisted of a cathode with sulfur (S) as the active material, electrolyte (solid-state or liquid), an anode (Li metal), and a separator (Figure 2 a).
In this part, we expect that the catalysts can speed up the reaction kinetics as much as possible, leading to a better electrochemical performance of batteries. Second, the formation of electrode–electrolyte interfaces in batteries is narrated in detail. This section shows the importance of selective catalysis for battery systems.
In principle, lead–acid rechargeable batteries are relatively simple energy storage devices based on the lead electrodes that operate in aqueous electrolytes with sulfuric acid, while the details of the charging and discharging processes are complex and pose a number of challenges to efforts to improve their performance.
For the past few years, a growing number of studies have introduced catalysts or the concept of catalysis into battery systems for achieving better electrochemical performance or designing materials with distinctive structures and excellent properties.
Carbons play a vital role in advancing the properties of lead-acid batteries for various applications, including deep depth of discharge cycling, partial state-of-charge, and high-rate partial state-of-charge cycling.
