“…1a is the charge and discharge end-of-potential during one run of PSoC test. 26 The calculated ratio of Pb and PbG plates are 0.45 and 1.11 respectively, which indicated that less PbSO 4 particles were present in the charged PbG plate. 1b The smaller potential drop of the PbG plate suggested that the addition of Gr suppresses sulfation.…”

In this article, we report the addition of graphene (Gr) to negative active materials (NAM) of lead-acid batteries (LABs) for sulfation suppression and cycle-life extension. Our experimental results show that with an addition of only a fraction of a percent of Gr, the partial state of charge (PSoC) cycle life is significantly improved by more than 140% from 7,078 to 17,157 cycles. The particle size on a charged Pb-graphene (PbG) plate after the PSoC test is also found to be reduced by around 25% when compare with a Pb plate. Charge and discharge densities measurements from the cyclic voltammetry (CV) test show an enhancement with the addition of Gr, indicating an improvement in the reversibility reaction of PbSO4. An electrochemical model, which takes into account of reduced interfacial resistance, improved charge transfer and enhanced electroactive surface area, is proposed to elucidate the role of Gr throughout the course of a PSoC cycle test. It is demonstrated that experimental results are aligned with our proposed model with enhanced cycle life performance, where PbG plate maintains a higher electroactive surface area for adsorption and desorption of Pb 2+ ions at the interface between active material and electrolyte occurs in parallel to reduced charge transfer.

“…PbSO 4 will quickly accumulate on the surface of negative electrode [75], which cannot be converted efficiently back to Pb during charge [76]. The accumulation of PbSO 4 reduces the effective reaction area of negative electrodes, makes the charge and discharge processes of the negative electrodes difficult, and finally leads to battery failure [77].…”

Summary The lead–acid battery (LAB) has been one of the main secondary electrochemical power sources with wide application in various fields (transport vehicles, telecommunications, information technologies, etc.). It has won a dominating position in energy storage and load‐leveling applications. However, the failure of LAB becomes the key barrier for its further development and application. Therefore, understanding the failure modes and mechanism of LAB is of great significance. The failure modes of LAB mainly include two aspects: failure of the positive electrode and negative electrode. The degradations of active material and grid corrosion are the two major failure modes for positive electrode, while the irreversible sulfation is the most common failure mode for the negative electrode. Introduction of carbon materials to the negative electrodes of LAB could suppress sulfation problem and enhance the battery performance efficiently. This paper will attempt here to pull together observations made by previous research to obtain a more comprehensive and integrative view of LAB failure modes. Moreover, according to a detail investigation to the battery market, we have drawn an objective and optimistic conclusion of LAB prospect. Copyright © 2016 John Wiley & Sons, Ltd.

“…Adding carbon materials into negative active mass (NAM) has been demonstrated as an effective method to suppress the sulfation . As the previous studies state, high conductive carbon materials like carbon black or carbon nanotubes– prolong the cycling life through enhancing the conductivity of negative electrode. Capacitive activated carbon or electrochemically active carbon materials act as tiny charge units to function as bumpers.…”

Long‐Life Lead‐Acid Battery for High‐Rate Partial‐State‐of‐Charge Operation Enabled by a Rice‐Husk‐Based Activated Carbon Negative Electrode Additive

et al. 2020

Lead sulfation severely shortens the cycling life of lead‐acid battery under high‐rate partial‐state‐of‐charge (HRPSoC) operation. Adding carbon materials into negative active mass has been demonstrated as an effective strategy to suppress the sulfation. In this paper, rice‐husk‐based activated carbon (RHAC) with high specific surface area and high pore volume exhibits excellent performances on enhancing the discharge capacity, the dynamic charge acceptance and especially the cycling life of negative electrode of lead acid battery. Results show that the HRPSoC cycling life of negative electrode with RHAC exceeds 5000 cycles which is 4.65 and 1.42 times that of blank negative electrode and negative electrode with commercial activated carbon, respectively. These outstanding performances are ascribed to the unique architectural properties of RHAC comparing with commercial activated carbon, such as three‐dimensional porous structure for acid storage, high mesopore volume for efficient ions transport and large external specific surface area for energetic Pb deposition.
