“…Since the electrolyte and the active substance inside the negative plate cannot interact due to the lead sulfate coating's high coverage, the cycle life will end. [ 53 ] While in a lead‐carbon battery, a conductive network of carbon grows around lead sulfate, encouraging the reduction of lead sulfate crystals during the charging process. The lead sulfate layer can be penetrated by carbon to allow electrolytes to be transported to the NAM inside the negative plate (Figure 8b).…”

Herein, a simple method to prepare porous carbon that inhibits hydrogen evolution is used, which has enormous advantages for both capacitors and lead‐acid batteries. The quantitative filter paper spongy porous carbon (SQFPC) is successfully synthesized by the two‐step method. SQFPC displays a porous, spongy structure with a large specific surface area (1847 m2 g−1). In electrochemical tests, SQFPC exhibits high specific capacitance (244 F g−1 at 1 A g−1) and a capacitance retention rate of 72.5% at 40 A g−1. In addition, the capacity of the battery with 0.5 wt% SQFPC is improved by 57.6% at a discharge rate of 0.1C, and the cycle life under the high‐rate partial state of charge is 9.3 times that of the blank battery. The enhanced battery performance is related to the unique structure and surface functional groups of carbon, which speed up ion movement inside the battery and provide active sites for lead deposition.

“…They formulated the following hypothesis: During charging, peroxide Pb 2 O 5 is formed on the positive plate, while the negative plate is reduced to a spongy lead state. A sub‐sulfate Pb 2 SO 4 is formed during the discharge at the negative electrode, while bioxide PbO 2 appears at the positive electrode 22 . The black color of the negative plate would be due to the Pb 2 SO 4 , which would be quickly transformed in the air into lead sulfate PbSO 4 (white) according to the reaction:

2 {Pb}_{2} {SO}_{4} + {normalH}_{2} {SO}_{4} + {normalO}_{2} \to 4 {PbSO}_{4} + {normalH}_{2} O .

Extracting the parameters of a lead‐acid battery under real‐world operating conditions is a significant part of solar photovoltaic (PV) engineering. Usually, the battery management system handles the battery system based on its model. However, its model's parameters can change due to its electrochemical nature. Hence, enhancing the model parameters' accuracy is required to achieve a reliable and accurate model. This research employs an improved methodology for extracting lead‐acid battery data outdoors. The suggested method combines numerical and analytical formulations of parametric battery models for solar PV energy storage. The Shepherd model, which considers the battery's non‐linear properties, is selected in this paper. Based on a modern meta‐heuristic marine predator algorithm, the parameters of two solar lead‐acid batteries are discovered using an optimal parameter identification technique (MPA). The MPA exhibits its capability in terms of fast convergence and accuracy. The acquired test results are compared to those produced by the salp swarm algorithm, artificial eco‐system optimizer, hunger games search, a new optimization meta‐heuristic method that inspires the behavior of the swarm of birds called COOT, and honey badger algorithm in terms of efficiency, convergence speed, and identification accuracy. The findings demonstrated that the MPA outperformed the other optimizers in identifying ability. This optimizer achieved 99.99% identification efficiency for both Bergan and Banner battery types, making it an excellent battery identification option.

Aqueous zinc‐based batteries have garnered considerable interest as promising energy storage devices due to the low cost, remarkable energy density, high safety, and eco‐friendliness. However, the mutual challenges of cathode dissolution, electrolyte parasitic reactions, disordered zinc dendrite growth, and easily punctured separator have significantly impeded the widespread commercialization of aqueous zinc‐based batteries. Realizing high‐performance zinc‐based batteries becomes imperative yet remains extremely challenging. To address these concerns, great efforts have recently been made to design high‐performance zinc‐based batteries. Here the state‐of‐the‐art in organic materials is critically reviewed for aqueous zinc‐based batteries, covering main components of a battery. This review provides a comprehensive overview on the design strategies of organic materials for zinc‐based batteries, encompassing cathode, anode, electrolyte, and separator. Furthermore, the challenges and prospective research directions are also discussed to provide a guideline for further development of highly stable zinc‐based batteries.
