“…However, the lowest R ct value of all belongs to C/Pb composite electrode indicates the largest electrochemically active surface area and the best charge acceptance of C/Pb composite electrode. The high specific surface area and pore volume of C/Pb composite electrode are attributed to the good connection between C/Pb composite and sponge lead [58][59][60] . On the other hand, different interface resistances between electrode and electrolyte can be identified from the EIS results [26] .…”

A novel C/Pb composite has been successfully prepared by electroless plating to reduce the hydrogen evolution and achieve the high reversibility of the anode of lead-carbon battery (LCB). The deposited lead on the surface of C/Pb composite was found to be uniform and adherent to carbon surface. Because lead has been stuck on the surface of C/Pb composite, the embedded structure suppresses the hydrogen evolution of lead-carbon anode and strengthens the connection between carbon additive and sponge lead. Compared with the blank anode, the lead-carbon anode with C/Pb composite displays excellent chargedischarge reversibility, which is attributed to the good connection between carbon additives and lead that has been stuck on the surface of C/Pb composite during the preparation process. The addition of C/Pb composite maintains a solid anode structure with high specific surface area and power volume, and thereby, it plays a significant role in the highly reversible lead-carbon anode.

“…Another possibility is to study this process itself, while it is appropriate to use such techniques that allow carrying information about either the composition or the particle size of the active substance. Such techniques include X-ray diffraction analysis (6), Raman spectroscopy (7) (both composition-oriented), and microscopic techniques such as SEM microscopy, AFM microscopy (8), or confocal microscopy (6).…”

Confocal Laser Scanning Microscopy (CLSM) is a widely used technique mainly in fields of biology or multidisciplinary material sciences. Although CLSM has the ability to monitor also electrochemical processes like lead sulfate-crystal growth, nobody used CLSM for such application. We performed operando observation of the pasted active mass of negative electrode for lead-acid batteries during deep cycling. Electrode with pasted negative active mass was optimized for cycling in ECC-opto-std electrochemical cell by EL-CELL. Lead sulfate crystal growth and changes of electrode surface during cycling were observed using a laser scanning confocal microscope Olympus Lext OLS4100. We evaluate the surface changes and sulfate crystal growth. The cycling mode leads to fast gradual degradation of the negative electrode and massive growth of lead sulfate crystals. Confocal laser scanning microscopy was identified as a powerful technique for visualization of lead sulfate crystal promotion during battery cycling.

Properties and Characterization Techniques of Graphene Modified Asphalt Binders

et al. 2023

Graphene is a carbon-based nanomaterial used in various industries to improve the performance of hundreds of materials. For instance, graphene-like materials have been employed as asphalt binder modifying agents in pavement engineering. In the literature, it has been reported that (in comparison to an unmodified binder) the Graphene Modified Asphalt Binders (GMABs) exhibit an enhanced performance grade, a lower thermal susceptibility, a higher fatigue life, and a decreased accumulation of permanent deformations. Nonetheless, although GMABs stand out significantly from traditional alternatives, there is still no consensus on their behavior regarding chemical, rheological, microstructural, morphological, thermogravimetric, and surface topography properties. Therefore, this research conducted a literature review on the properties and advanced characterization techniques of GMABs. Thus, the laboratory protocols covered by this manuscript are atomic force microscopy, differential scanning calorimetry, dynamic shear rheometer, elemental analysis, Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, thermogravimetric analysis, X-ray diffraction, and X-ray photoelectron spectroscopy. Consequently, the main contribution of this investigation to the state-of-the-art is the identification of the prominent trends and gaps in the current state of knowledge.
