| 總結: | Although lithium metal anode has irreplaceable advantages, such as ultra-high specific energy density and ultra-low redox potential, a variety of issues, i.e., short cycle life, low Coulomb efficiency, and tendency to cause fire explosions caused by lithium dendrite growth and high reactivity to the electrolyte, seriously hinder the practical progress of lithium metal anode. This perspective summarizes how 3D lithiophilic materials have stabilized lithium metal anodes in recent years by improving the uneven deposition of lithium metal, alleviating the volume expansion of lithium metal anodes, and limiting dendrite growth. Simultaneously, the issues of the 3D composite lithium anodes in practical application are concluded and the research direction of 3D composite lithium anode is prospected.
