Abstract 3D porous current collectors (CCs) play a critical role in ensuring uniform lithium (Li) deposition and distributing density evenly across electrode surfaces. These attributes are essential for improving the safety stability of Li metal batteries. However, copper (Cu) ‐based CCs face notable drawbacks, such as rigid structures, insufficient pore volume, excessive mass, weak intrinsic lithiophilicity Li, which hinder their performance. To overcome these limitations, novel...
