An electrochemically roughened Cu current collector for Si-based electrode in Li-ion batteries

Critical roles of binders and formulation at multiscales of silicon-based composite electrodes

“…Similarly, Lee and Oh proposed the introduction of a graphene/PVdF conductive layer between the current collector and the silicon-based layer [67]. Reyter et al evaluated an electrochemically roughened copper foil as a current collector for micrometric Si powder based electrodes prepared by the conventional slurry-coating method [68]. The formation of a bunch of copper nanowires on the current collector makes a rough surface, which enhances the adhesion of the composite electrode (Fig.…”

Silver-nickel oxide core-shell nanoparticle array electrode with enhanced lithium-storage performance

“…For instance, Reyter et al evaluated a roughened copper foil as a current collector by electrophoretic deposition method for Si powder based electrodes, which showed stable and long-cycle life [33]. Liu et al reported the synthesis of nanoporous Ni current collector via polystyrene microsphere assisted method to enhance the volumetric capacity of nanostructured Li-ion battery anode [34].…”

Biomimetic Nanostructuring of Copper Thin Films Enhances Adhesion to the Negative Electrode Laminate in Lithium‐Ion Batteries

“…These metals are used because of their resistance against oxidation and because they are ubiquitous, however, they are susceptible to environmental degradation. [7] However, although these have been shown to alleviate the adhesion issues between the binder and the active material, they can incur high production cost, or disturb electrode uniformity. The critical adhesion force between laminate and copper is provided by the interaction be-tween a binder and the native oxide layer on copper.…”
