“…The introduction of lithophilic nanoparticles as seed sites can effectively control the nucleation behavior of lithium, and common nanoparticles that can be used as seeds are Zn single atoms/nanoparticles, Si, noble metals (Au and Ag), and some metal compounds. − Yang et al induced lithium nucleation and growth by introducing Zn SAs on the MXene nanosheets. As a result of the abundant Zn SAs, lithium tends to nucleate uniformly on Zn–MXene, resulting in an ultralong cycle life of 1200 h. Self-supporting MXene@Zn@Li designed by Feng et al shows excellent reversibility, in which Zn can effectively induce the uniform nucleation of lithium as a nucleating agent.…”

Lithium−sulfur batteries (LSBs) are a new type of energy storage system with great potential, which has an ultrahigh energy density of 2600 Wh kg −1 . However, the polysulfide shuttle and dendrite growth have seriously impeded practical applications. As a new type of twodimensional (2D) transition metal carbide/nitride, MXene possesses the advantages of metal conductivity, structural diversity, and abundant terminal groups. Thus, it is beneficial to regulate the dynamic process of ions, which make it widely applied in LSBs. Guided by the multifunction of MXene in LSBs, this work summarizes the application of MXene for cathode construction, separator modification, anode protection, and electrolyte regulation. Recent related works are reviewed from the aspects of MXene-based morphology adjustment, element doping, surface modification, and composite material construction. Finally, the challenges and application prospects of MXene are prospected.

Lithium(Li) metal is an anode candidate for rechargeable batteries due to its ultra‐high theoretical capacity and extremely low standard potential. However, the dendritic Li and dead Li have hindered the practical application of next‐generation batteries. Constructing 3D anode current collectors can not only decrease the local current density but also relieve the volume expansion. Herein, the 3D Ni nano‐starfish@Al(NSA) is synthesized as anode current collectors. Compared with the 3D Ni nano‐cone@Al(NCA) with sharp cone tips, the NSA shows a superior cycle performance, especially at high current density. This is because the NSA has a more uniform surface curvature than NCA, which makes the electric field distribution more homogeneous and reduces the local electric field, thereby inducing the even deposition of Li and suppressing the growth of Li dendrites. The NSA@Li anode gives superior cycling performance over 2800 h at a current density of 4 mA cm−2 in a symmetric cell. A full cell paired with LiFePO4 cathode shows high Coulombic efficiency of 96.8% approaching 200 cycle‐life at 0.5 °C. This work provides a view of the microstructure design of current collectors for achieving better performance Li metal batteries.
