“…[ 30 ] Under an overpotential of −200 mV, the current of the cell with bare Zn kept increasing beyond 200 s, which indicates a long and frantic planar diffusion process with deposition extension. [ 31 ] During the charge/discharge process, in order to lower the surface energy, zinc ions tend to accumulate on the tips and grow up on the surface of the anode, [ 32 ] which is schematically shown in Figure 3l. On the contrary, the KL‐Zn proceeds into a stable 3D diffusion process after only 30 s planar diffusion and nucleation process, suggesting that Zn 2+ seemed to be reduced to Zn 0 with the function of confined 3D diffusion.…”

Zinc metal is considered as one of the best anode choices for rechargeable aqueous Zn-based batteries due to its high specific capacity, abundance, and safety. However, dendrite and corrosion issues remain a challenge for this system. Herein, sieve-element function (selective channel of Zn 2+ ) and uniform-pore distribution (≈3.0 nm) of a kaolin-coated Zn anode (KL-Zn) is proposed to alleviate these problems. Based on the artificial Zn metal/electrolyte interface, the KL-Zn anode not only ensures dendritefree deposition and long-time stability (800 h at 1.1 mA h cm −2 ), but also retards side reactions. As a consequence, KL-Zn/MnO 2 batteries can deliver high specific capacity and good capacity retention as well as a reasonably well-preserved morphology (KL-Zn) after 600 cycles at 0.5 A g −1 . This work provides a deep step toward high-performance rechargeable Zn-based battery system.

“…[ 17 ] Since the lithiation voltage of graphite (≈0.1 V on average vs Li + /Li) is higher than the lithium deposition voltage, graphite anodes can prevent detrimental lithium dendrite formation. [ 18 ] The replacement of lithium metal anodes with intercalated anode materials (like graphite) remarkably enhances battery safety and drives the revolution from lithium metal batteries to “rocking‐chair” lithium‐ion batteries. The successful turn can provide a source of reference for the future advances and direction of “rocking‐chair” Zn‐ion batteries.…”

Various organic electrodes have been developed for Zn‐ion batteries, such as diquinoxalino[2,3‐ a :2′,3′‐ c ] phenazine (HATN) based on proton insertion, [ 50 ] polyaniline based on Zn 2+ insertion/extraction and dual‐ion mechanisms, [ 51 ] pyrene‐4,5,9,10‐tetraone electrode with supercapacitor‐like power behavior, [ 52 ] phenanthrenequinone macrocyclic trimer, [ 53 ] etc.…”

In the past decades, the world has witnessed the successful commercialization of “rocking‐chair”‐type lithium‐ion batteries with lithium metal free anodes. Owing to their safe, green, easy manufacturing, and cost‐efficiency characteristics, rechargeable zinc batteries have recently received more and more attention. However, the practical application of Zn metal batteries is hampered mainly by the dendritic growth of Zn metal anode, which leads to poor Coulombic efficiency, hazards, and various side reactions. Herein, the emerging “rocking‐chair”‐type Zn‐ion batteries are systemically reviewed with Zn host anodes instead of Zn metal anodes. As an introduction, the fundamental principles, advantages, and challenges of “rocking‐chair”‐type Zn‐ion batteries are discussed. Subsequently, the design principles and recent advances of cathode, anode, and electrolyte for “rocking‐chair” Zn‐ion batteries are summarized. To conclude, perspectives on the future of “rocking‐chair” Zn‐ion batteries are presented. It is hoped that this review may provide alternative directions for the design of Zn‐ion batteries.
