Lithium metal, as the “Holy Grail” of lithium battery anodes, is promising to be used in the next-generation of high-energy-density storage devices. However, serious safety risk and poor cycle performance are inevitable when bare lithium foil is used as the anode material, due to the uncontrolled growth of lithium dendrites, unstable solid electrolyte interface, and infinite volume expansion of lithium during cycling, which largely hinder the further commercial application of lithium metal batteries (LMBs). The utilization of up-to-date current collectors with specific composition and structure is believed to be effective to overcome these shortcomings. However, a systematic evaluation of the merit of different current collector materials for realizing high-performance lithium metal anodes is still lacking. This review summarizes the fashionable advanced current collector materials for long-life LMBs in recent years. The superiorities and related electrochemical performances by using these current collector materials are discussed in detail. It is expected that this review may promote the rational choice of appreciatory current collector materials with unique structure designs to extend the cycle life of lithium metal anodes for achieving the next-generation of high-energy-density LMBs.

用于高性能锂金属阳极的先进集流体材料
金属锂作为锂电池负极的“圣杯”，有望用于下一代高能量密度存储设备。然而，当使用裸锂箔作为负极材料时，由于锂枝晶生长不受控制、固体电解质界面不稳定以及锂在循环过程中体积无限膨胀，严重的安全风险和较差的循环性能是不可避免的，这在很大程度上阻碍了锂的进一步发展。锂金属电池（LMB）的商业应用。使用具有特定组成和结构的最新集电器被认为可以有效克服这些缺点。然而，仍然缺乏对不同集流体材料在实现高性能锂金属负极方面的优点的系统评价。本综述总结了近年来流行的长寿命LMBs先进集流体材料。详细讨论了使用这些集流体材料的优势和相关的电化学性能。预计本综述将促进对具有独特结构设计的增值集流体材料的合理选择，以延长锂金属负极的循环寿命，从而实现下一代高能量密度的LMBs。
