Achieving high-current-density and high-areacapacity operation of Li metal anodes offers promising opportunities for high-performing next-generation batteries. However, high-rate Li deposition suffers from undesired Liion depletion especially at the electrolyte-anode interface, which compromises achievable capacity and lifetime. Here, electronegative graphene quantum dots are synthesized and assembled into an ultra-thin overlayer capable of efficient Liion adsorbing at the nanoscale on Li-metal to fully relieve Liion depletion. The protected Li anode achieves long-term reversible Li plating/stripping over 1000 h at both superior current density of 60 mA cm À2 and areal capacity of 60 mAh cm À2 . Implementation of the protected anode allows for the construction of Li-air full battery with both enhanced rate capability and cycling performance.

“…[14][15][16] 3D current collectors, which are conducive to cushioning volume expansion and homogenizing electric field distribution, have spurred burgeoning research interest in ameliorating Li plating/stripping operation. [17][18][19][20][21][22][23] In this respect, it still remains a formidable challenge to acquire low Li nucleation overpotential due to the lithiophobic property of common current collectors (e.g., Cu, Ni, C), thereby inescapably triggering Li dendrite formation. [24] In addition, the spontaneously derived solid electrolyte interface (SEI) is prone to crack and form repetitively, therefore further deteriorating the Li dendrite issue.…”

Li metal is regarded as one of the most promising anodes for next‐generation rechargeable batteries. Nonetheless, infinite volume change and severe dendrite growth impede its practicability. To date, unremitting efforts have been devoted to stabilizing Li metal anode via the rational design of 3D current collectors. In this sense, optimizing Li nucleation behavior plays a pivotal role in alleviating the dendrite formation. Herein, a practically viable route is devised by in situ crafting lithiophilic CuSe granules on the dealloyed Cu skeleton (D‐Cu@CuSe). Persuasive electrochemical analysis and systematic theoretical calculation disclose the underlying Li nucleation mechanism on the CuSe overlayer. Impressively, the D‐Cu@CuSe‐Li symmetric cell can sustain a stable plating/stripping operation over 1000 h at a high depth of discharge at 62.5%. More crucially, when paired with high‐loading sulfur cathodes, D‐Cu@CuSe‐Li||S batteries harvest advanced areal capacity and stable cycling performance even under stringent working conditions of low negative‐to‐positive (N/P) (≈2) and electrolyte‐to‐sulfur (8 μL mgs−1) ratios. Overall, a fresh perspective into rationalizing current collector design is afforded, which extends Li utilization and cycling durability in the pursuit of pragmatic Li metal anodes.

“…Cautious should be taken about the amount of the lithiophilic material in the 3D current collectors in order to ensure the high practical gravimetric and volumetric energy density of the anode. Some metal compounds that undergo conversion reactions with lithium can also affect the morphology of the deposited lithium and reduce the nucleation overpotential, such as metal oxides (ZnO (Jin C. et al, 2017;Sun et al, 2019a;Zhao et al, 2019;Yue et al, 2020), CuO (Zhang C. et al, 2018;Huang et al, 2019;Wei et al, 2020;Huang et al, 2021), Cu 2 O SnO 2 ), fluorides (CuF 2 (Yan C. et al, 2018), NiF 2 (Peng et al, 2017)), phosphides (Cu 3 P) Sun et al, 2019b) and nitrides (Cu 3 N) (Lee D. et al, 2020;Li et al, 2021). Zhang et al (Zhang C. et al, 2018) prepared lithiophilic CuO nanosheets modified Cu foil by a simple wet chemical reaction to stabilize the lithium nucleation and alleviate the growth of lithium dendrites, thus enhancing the lithium plating and stripping performance.…”

Lithium metal is a promising anode material for its low redox potential and high theoretical specific capacity. However, the commercial application of the lithium metal anode is hindered with safety concerns arising from the uncontrolled growth of the lithium dendrites and significant volume variation during the lithium plating and stripping processes. Modification to the current collector is effective in tailoring the morphology of the deposited lithium and improving the cycling performance of the lithium metal batteries This review summarizes at first the global research advances in the structural design and the selection of the current collectors and their textures. It then presents some of our efforts in realizing controlled lithium deposition by designing current collectors in three aspects, lithium deposition induced by the micro-to-nano structures, lithiophilic alloys and iron carbides. Finally, conclusions and prospects are made for the further research of the current collectors.
