The lithium metal anode is a competitive candidate for next‐generation lithium‐ion batteries for its low redox potential and ultra‐high theoretical specific capacity. Nevertheless, obstacles regarding heterogeneous lithium deposition, dendrite growth, and poor Coulombic efficiency limit its practical application. Among rational electrode designs, carbon materials have been regarded as feasible hosts for stabilizing lithium to address the above issues due to their light weight, high conductivity, and adjustable physicochemical properties. Therefore, tremendous efforts have been made to design stereoscopic carbon materials with multitudinous lithiophilic sites and large specific surface areas to facilitate rapid lithium‐ion flux, nucleation and mitigate lithium dendrite formation by controlling the kinetics of lithium deposition. Furthermore, the mechanism of lithium plating/stripping is commendably elucidated with the help of advanced in situ characterization techniques. This progress report systematically reviews progress in carbon materials/lithium composite anodes for lithium metal batteries and the detailed parts are as follows: 1) carbon/lithium composite methods; 2) design lithiophilic mechanism; 3) various carbon materials substrates; 4) advanced in situ characterization techniques for lithium metal anodes; and 5) prospects toward the practical applications of advanced lithium metal batteries. This review provides new insights into lithium metal batteries’ technological development and practical application.

[ 20,21 ] To mitigate and ameliorate the problems of lithium dendrite, many solutions are proposed, such as modifying the surface of lithium metal anode, [ 22–24 ] optimizing electrolyte, [ 25–28 ] and decorating the current collector, [ 29–33 ] and so on.

of lithium metal anode, [22][23][24] optimizing electrolyte, [25][26][27][28] and decorating the current collector, [29][30][31][32][33] and so on. However, the study on the modifying separator in LMBs is rare. [34,35] As an important component of batteries, the separators are able to remain stable in the air. [35] Therefore, modifying the separator is a relatively cheap and conventional way in favor of mass production. [36] In our previous report, [35] a lithiated SiO microparticles and polyacrylic acid were coated on the polyethylene separators. The batteries with the modified separators not only have the suppression of dendrite, but also have superior electrochemical performance.The main principle of designing separators is that the modified separator has the effect of suppression of lithium dendrite without sacrificing the normal function. In the previous report, [37] bismuth (Bi) can alloy with lithium to reduce the deposition overpotential and reduce the dendrite growth. Moreover, Bi as anode material has attracted great attention in aqueous energy storage, LIBs and sodium-ion batteries with low-cost, high volumetric capacity density, and safety. [38,39] To the best of our knowledge, there is no report on Bi for separator modifying.In this work, a low cost, high efficiency, and scalable dealloying method was developed to synthesize nano-sized Bi by chemical etching the Al 90 Bi 10 alloy. The synthesized nano-sized Bi was used as the modifying material of the polyethylene (PE) separator for the lithium metal batteries and the anode materials for the potassium ion batteries (KIBs). For LMBs, the Bi-modified PE separator had the good wettability of electrolyte and the effect of suppression of lithium dendrite by the experiment and the first-principle calculations. On the contrary, the nano-sized Bi showed a good electrochemical performance for KIBs.The ORCID identification number(s) for the author(s) of this article can be found under

“…In this respect, the superior electrical conductivity and mechanical properties of graphene make this an ideal and desirable current collector material. [28][29][30] However, the application of graphene as a current collector in ZIBs requires a suitable manufacturing process for making the graphene into a film. 31 Among the various possible approaches, the stacking of graphene is particularly promising due to the easy fabrication of films with suitable thicknesses for use as the current collector.…”

“…Unfortunately, the application of heat to remove the oxygen can lead a poor interfacial adhesion of the electrode materials to the current collector due to low wettability, which can lead to a low reversibility. [25][26][27][28][29][30][31][32][33][34][35][36][37] Therefore, there is an urgent need to develop a desirable current collector capable of improving the electrical conductivity and interfacial adhesion between the electrode material and the current collector.…”

Zinc-ion batteries (ZIBs) are considered as a reasonable alternative to lithiumion batteries (LIBs) due to their satisfactory safety levels, low cost, and ecofriendliness. Nevertheless, the ZIBs have suffered from rapid capacity fading and unstable cycling stability due to poor reversibility. To overcome this issue, a suitable current collector with high electrical conductivity and good interfacial adhesion to the electrode material is essential. Herein, for the first time, an improved-quality graphene film (IQGF) is uniformly decorated with ultrafine manganese oxide nanoparticles (UFMP) and the resulting UFMP@IQGF composite is used as a multifunctional current collector. The asfabricated ZIB exhibits a superb energy storage performance and reversibility, with an improved specific capacity of 404.7 mA h g À1 at a current density of 0.1 A g À1 , and an excellent ultrafast cycling stability, with a capacity retention of 83.7% for up to 300 cycles at a current density of 2.0 A g À1 . Moreover, the all-solid-state ZIB using a gel-electrolyte exhibits a good energy storage performance, mechanical flexibility, and feasibility for practical applications.
