“…The current collectors serve as a substrate to collect and transfer electrons from active materials and external circuits, as well as support active materials in the battery fabrication. 38,93,120,121 Commercial Li-ion batteries employ Al and Cu as cathode and anode current collectors, respectively, due to their high electrochemical stability toward oxidation and reduction, low cost, and excellent electrical conductivity. Flexible batteries demand for extra features such as high mechanical stability under deformation and improved adhesion between current collectors and electrode materials.…”

“…In this case, the oxide groups in the current collector could bind more effectively with the CMC binder, and the rough-surface Cu foil could have a higher surface area and tighter contact between Si and Gr. 26 Otherwise, the slurry's surface tension can be reduced by adding a cosolvent such as isopropanol. 16 An alternative explanation for the cracks formed in this thick electrode could be the mixing sequence that may affect the casted properties of the electrode.…”

The manufacturing process aims to optimize the parameters leading to enhanced Lithium-Ion Battery (LiB) electrode properties. Particularly, developing silicon/graphite blends could be an alternative for boosting LiB energy density while using the longstanding properties of graphite. Here, we report the manufacturing parameters impact of the mixing, coating, and calendering steps on the properties of silicon/graphite blend electrodes. The mixing process was assessed by the solid and silicon content dependency, where the viscosity increases when increasing the solid and decreasing the silicon content. Moreover, the slurry rheology directly impacts the mechanical stability of the electrode when coating using thicker comma gaps. The calendering step evidences a porosity threshold necessary for adequate ionic resistance and cycling life. We found that porosities between 45% to 56% for these silicon/graphite blends yield higher performance. Lower than 30% porosity highly impacts the electrochemical performance in a detrimental way.

Rechargeable aqueous zinc batteries (AZBs) are one of the promising options for large‐scale electrical energy storage owing to their safety, affordability and environmental friendliness. During the past decade, there have been remarkable advancements in the AZBs technology, which are achieved through intensive efforts not only in the area of electrode materials but also in the fundamental understandings of non‐electrode components such as electrolytes, solid electrolyte interphase (SEI), current collectors, binders, and separators. In particular, the breakthroughs in the non‐electrode components should not be underestimated in having enabled the AZBs to attain a higher energy and power density beyond that of the conventional AZBs, proving their critical role. In this article, the recent research progress is comprehensively reviewed with respect to non‐electrode components in AZBs, covering the new‐type of electrolytes that have been introduced, attempts for the tailoring of SEI, and the design efforts for multi‐functional current collectors, binders and separators, along with the remaining challenges associated with these non‐electrode components. Finally, perspectives are discussed toward future research directions in this field. This extensive overview on the non‐electrode components is expected to guide and spur further development of high‐performance AZBs.
