“…Furthermore, VG nanosheets and carbon black, which are both non‐polar sp 2 carbon materials, can be tightly connected through strong π‐π interactions. At the interface between the electrode and VG−Al, carbon black nanoparticles were indeed found to be spread evenly on the VG nanosheets, which indicated that the conductive network in the electrode was in tight contact with the current collector, resulting in a low interfacial resistance [104] …”

Vertically oriented graphene (VG) nanosheets exhibit unique structural characteristics, such as large accessible surface area, rich edges, high electrical conductivity, open network channels, and agglomeration resistance, for electrochemical energy‐storage applications (e. g., supercapacitors, lithium‐ion batteries, etc.). In this Review article, we summarize recent progress in the design and engineering of VG‐based electrodes for high‐performance electrochemical energy technologies within the context of energy‐storage mechanisms and charge‐transfer kinetics, and include a perspective to highlight the challenges and promises in the exploitation of vertically oriented two‐dimensional carbon nanostructures for further enhancement of the performance of electrochemical energy‐storage devices.

Fast-charging batteries have attracted great attention, and are anticipated to charge electrical vehicles and consumer electronics to full-capacity in several minutes. However, commercial electrode materials in batteries generally have a limited rate performance and are difficult to be used in fast-charging batteries. Designing electrodes with an aligned structure is an effective way to shorten the ion transport path and improve the rate performance of a battery. The excellent electronic conductivity of carbon-based electrodes is another key factor for increasing the rate capability of rechargeable batteries. Therefore, aligned carbon-based electrodes (ACBEs) can significantly improve the power density by combining the advantages of an aligned structure and carbon-based materials. In this review, the mechanism, advantages, and challenges of ACBEs for fast-charging batteries are evaluated, and then the design and preparation methods of ACBEs based on their different dimensions are summarized, and their applications in different batteries are illustrated. Finally, the future development of ACBEs for fast-charging batteries is considered.

“…Ni catalyst also played a great role there, boosting the growth rate, density, and quality of the growing graphene sheets. Wang [10] investigated the vertical graphene nanosheets that were grown on commercial Al foil by the plasma-enhanced chemical vapor evaporation method. They form a robust connection with a carbon-based conductive electrode network and thus greatly reduce the electrode current collector interfacial resistance.…”

Vertical Graphene Growth on AlCu4Mg Alloy by PECVD Technique

Vertical graphene, which belongs to nanomaterials, is a very promising tool for improving the useful properties of long-used and proven materials. Since the growth of vertical graphene is different on each base material and has specific deposition setting parameters, it is necessary to examine each base material separately. For this reason, a full factor design of experiment was performed with 26 = 64 rounds, which contained additional 5 central points, i.e., a total of 69 rounds of individual experiments, which was to examine the effect of input factors Temperature, Pressure, Flow, CH4, Plasma Power, and Annealing in H2 on the growth of vertical graphene on aluminum alloy AlCu4Mg. The deposition was performed using plasma-enhanced chemical vapor deposition (PECVD) technology. Mainly, the occurrence of graphene was analyzed, which was confirmed by Raman spectroscopy, as well as its thickness. The characterization was performed using electron and transmission microscopy, including an atomic force microscope. It was found that the growth of graphene occurred in 7 cases and its thickness is affected only by the interaction flow (sccm) × pretreatment H2 (sccm).
