“…The accumulation of hard crystals significantly hinders current distribution and electrolyte diffusion and limits cycle life. The State-of-Charge (SoC) of the battery is related to the electrochemical double layer (EDL) structure as reported by Kirchev et al 11,[22][23][24] It was found that the formation of PbSO 4 could modify the EDL structure and reduced the electroactive surface area that participates in the charge and discharge processes. 10,11 It is well-recognized that carbon additives are the most widely used materials in controlling 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.

“…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].…”

<p class="PaperAbstract">This paper is in the memory of the big Bulgarian scientist Professor Zdravko Stoynov. An original and non-standard personality with the spirit of a gentleman, he turned all that he touched into a masterpiece. His innovative thinking which made him one of the world’s leaders in Electrochemical Impedance Spectroscopy, chiseled away at the scientific taboos and created new scientific horizons. Zdravko Stoynov left us an abundant heritage – his spirit, his interminable capacity to wonder, his developments and inventions – all that he has taught us and brought up with. It has no dimensions but rather carries a unique value.</p>
