“…Please do not adjust marginsPlease do not adjust margins directly related to the formation of PbSO 4 on the electrode surface, as supported by our SEM observation as well as in the reported literature 5,11,14,16. In addition, we assume that thesurface coverage of PbSO 4 on the Pb/PbG electrode surface could also affect the charge and discharge performance of the cell.…”

“…At the initial stage, a typical oxidation peak where Pb is oxidized to PbSO 4 can be found at approximately −0.65 V, and a typical reduction peak where PbSO 4 is reduced back to Pb can be found at around −1.2 V. 6,12 It can be seen that there were no significant shift of the oxidation and reduction potentials with the addition of Gr. Similar models were adopted by other researchers 11,23,30,31 for studying the electrochemical reactions in LAB. The higher oxidation and reduction current density suggests that the PbG plate has a higher utilization of Pb active particles.…”

“…The decreasing DL capacitance trend as cycle number increases agreed with our proposed model. 11 With the combination of reduced interfacial resistance, improved charge transfer and enhanced number of electroactive sites brought by Gr, it is likely that the reaction of formation and dissolution of PbSO 4 crystals on PbG plate occur at a faster rate than that on Pb plate. 35 It can be seen that DL capacitance values decreased at a faster rate for Pb plate when compared to that of the PbG plate.…”

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.

“…The method is highly appreciated by the experts in the field of impedance spectroscopy and presented in recent monographs and surveys [35][36][37][38]. As an advanced development, DIA gradually enters in the impedance analysis and is already successfully applied for studies of electrochemical energy sources and other systems [39][40][41][42][43][44][45][46][47][48].…”
