      abstract     = {In zero-excess lithium metal batteries (ZELMBs), also
                      termed “anode-free” LMBs, Li from the positive electrode
                      is electrodeposited onto a bare current collector instead of
                      the Li metal negative electrode commonly used in LMBs. This
                      enables high theoretical energy density and facile, safe,
                      and low-cost assembly. To tackle coulombic inefficiencies
                      during Li deposition/dissolution, 3D structured current
                      collectors can be used instead of 2D foil materials. This
                      study elucidates the Li deposition behavior in custom-made
                      open-porous Cu micro-foams from nucleation to large scale
                      deposition. For the first time in ZELMBs, surface and
                      sub-surface Li deposits in open-porous 3D materials are
                      compared to deposits on 2D foils using cryogenic focused ion
                      beam scanning electron microscopy (cryo-FIB-SEM). The
                      results highlight that Cu micro-foams can store substantial
                      amounts of dendrite-free Li in their open-porous 3D
                      structure, minimizing detrimental volume changes during Li
                      deposition/dissolution. Electrochemical analyses and
                      simulations reveal that current density distribution over
                      the large surface area of the Cu micro-foams reduces the Li
                      nucleation overvoltage by $≈40\%.$ Also, charge/discharge
                      cycling in ZELMBs shows increases in coulombic efficiency,
                      capacity retention, and cycle life. Overall, this work
                      explains how open-porous Cu micro-foam current collectors
                      improve the Li deposition behavior to boost the cycling
                      characteristics of ZELMBs.},
