“…Based on this theory, various 3D current collectors were developed to buffer the dendrite growth for Li metal anode counterpart, 46,47 including 3D Cu foam, 48 3D Zn/Carbon Nanotube(CNT) framework, 49,50 and Cu mesh 51 . Achievements in prolonging the lifespan were obvious, a good case in point is that the designed 3D Zn@CNTs (Figure 3E) reported by Lu et.al presented homogenous precipitation of Zn and showed a much‐prolonged lifespan in a symmetric cell with more than 200 hours stable stripping and platting (Figure 3F).…”

Rechargeable Zn‐based batteries (RZBs) have attracted much attention and been regarded as one of the most promising candidates for next‐generation energy storage featured with high safety, low costs, environmental friendliness, and satisfactory energy density. The aqueous electrolyte system exhibits great potential to power the future wearable electronics. Apart from the achievements of high capacity cathode and stable electrolyte, the anode suffers from problems of dendrite growth, hydrogen evolution, and passivation with limited attention. The dendrite formation strongly restricts the battery lifespan. Therefore, strategies focused on dendrite suppression are carefully categorized and summarized in this review, including crystallographic orientation manipulation, electric field control, ion flux regulation, and mechanical shield. Each strategy and the detailed approaches are critically dissected. Finally, remaining challenges are emphasized in this review, expecting to supply further research with potential directions to fulfill the high performance of the Zn anodes.

“…The modification strategies for Zn-metal anodes are similar to those of alkali-metal anodes. Up to now, a great deal of strategies have been proposed, such as constructing 3D current collectors, [121][122][123] providing a host for the "hostless" Zn anode, [124][125][126] modifying liquid electrolytes, [127][128][129] utilizing solid-state electrolytes, [130][131][132] alloy engineering, [133] using zincophilic substrates, [134] interfacial design, [135][136][137] adding seeds to regulate Zn deposition, [138] and designing multifunctional separators.

Metal anodes based on a plating/stripping electrochemistry such as metallic Li, Na, K, Zn, Mg, Ca, Al, and Fe have attracted widespread attention over the past several years because of their high theoretical specific capacity, low electrochemical potential, and superior electronic conductivity. Metal anodes can be paired with cathodes to construct high-energy-density rechargeable metal batteries. However, inherent issues including large volume changes, uncontrollable growth of dangerous dendrites, and an unstable solid electrolyte interphase (SEI) hinder their further development. MXene as an emerging 2D material has shown great potential to address the inherent issues of metal anodes due to its 2D structure, abundant surface functional groups, and the ability to construct macroscopic architectures. To date, under the assistance of MXene, various strategies have been proposed to achieve stable and dendrite-free metal anodes, such as MXene-based host design, designing metalphilic MXene-based substrates, modifying the metal surface with MXene, constructing MXene arrays, and decorating separators or electrolytes with MXene. Herein the applications and advances of MXene in stable and dendrite-free metal anodes are carefully summarized and analyzed. Some perspectives and outlooks for future research are also proposed.

“…[173,216] Recently, Xu et al [253] demonstrated a stable 3D Zn anode by electrodepositing Zn onto a facile NH 3 • H 2 O etched nano-porous Cu skeleton (Figure 19a). The Zn on the Cu skeleton is uniform and compact, can reversibly plating/ stripping with fast electrochemical kinetics and high Coulombic efficiency almost 100 % for 350 h. In addition, commercially available Cu, [264][265][266] Ni [255] foams and Cu meshes [216] are also feasible alternatives of nanostructured Cu skeleton to stabilize Zn metal anodes, in both neutral and alkaline electrolytes.…”
