“…To evaluate the electrochemical performance of the synthesized CNT@Cu, a half-cell test was conducted using physically etched Zn metal as the counter electrode. 36 Figure 2A illustrates the timevoltage profiles of Zn plating/stripping behavior occurring in the half-cell applying CNT@Cu/bare Cu as a working electrode. Zn was deposited on the working electrode at a current density of 1 mA cm -2 for 1 h, followed by stripping at a cut-off voltage of 0.5 V in the half-cell experiment.…”

As an alternative to Li‐ion batteries, aqueous Zn batteries have gained attention due to the abundance of Zn metal, low reduction potential (–0.76 V vs. standard hydrogen electrode), and high theoretical capacity (820 mAh g–1) of multivalent Zn2+ ion. However, the growth of Zn dendrites and the formation of irreversible surface reaction byproducts pose challenges for ensuring a long battery lifespan and commercialization. Herein, the Cu foil coated with a single‐walled carbon nanotube (SWCNT) layer using a facile doctor blade casting method is utilized. The SWCNT‐coated Cu foil demonstrates a significantly longer battery lifespan compared to the bare Cu in the half‐cell tests. Through operando optical microscopy imaging, we are able to provide intuitive evidence that Zn deposition occurs between the carbon nanotube (CNT) coating and Cu substrate, in agreement with the computational results. Also, with various imaging techniques, the flat morphology and homogeneous distribution of Zn beneath the SWCNT layer are demonstrated. In addition, the full‐cell using CNT‐coated Cu exhibits a long cycle life compared to the control group, thereby demonstrating improved electrochemical performance with limited Zn for the cycling process.

Dissipative self‐assembly (DSA) system requires a continuous supply of fuels to maintain the far‐from‐equilibrium assembled state. Living organisms exist and operate far from the thermodynamic equilibrium by continuous consumption of energy taken from the surroundings, so how to realize the construction of the artificial DSA system has attracted much attention by researchers all over the world. Owing to dynamic controllable noncovalent interactions, artificial supramolecular DSA systems have achieved higher functions fueled by various types of energy, such as chemical fuels, light, electric energy, acoustic energy, and mechanical energy. Upon the input of external fuels, nonactive precursors can be activated to form building blocks at higher energy levels and then self‐assemble into transient supramolecular structures. As the proceeding of deactivation reaction, the building blocks with higher energy level dissipate back to the initial precursors, resulting in the disassembly process, to complete a full cycle. In this review, we summarize the recent advances of artificial supramolecular DSA systems on its construction strategies and energy‐fueled regulation approaches. The applications of supramolecular DSA systems in luminescence modulating, information encryption, self‐regulating gels, drug delivery, and catalysis are also discussed. We hope that this review article will facilitate further understanding and development of DSA systems.
