Summary: To address the obstacles of lithium dendrite growth and volume change, as well as poor mechanical properties of SEI, an ultralight CF-Mg3N2 was fabricated as a collector. The CF-Mg3N2 composite enabled homogeneous lithium deposition/stripping with low nucleation overpotential, high Coulombic efficiency, and long cyclability. The Mg3N2-CF@Li//LiFePO4 full cells also exhibited better rate capability and cycling stability, showing practicality. This work's design concept has a far-reaching influence on developing a stable Li metal anode.

Summary: In this study, a simple method was developed to grow vertically aligned ZnO nanoflakes on the surface of 3D Cu foam through an electrochemical synthetic process. The unique structure of the nanoflakes effectively suppressed the growth of lithium dendrites, increasing the number of lithium metal nucleation sites and the specific surface area of the anode. As a result, the performance of lithium metal batteries was greatly improved.

Summary: Researchers developed a Cu-based current collector with a super-three-dimensional lithiophilic modification layer for anode-free lithium metal batteries. The modification layer, consisting of highly dispersed CuOx sites in the O-containing defective carbon, effectively reduces nucleation overpotential and promotes uniform dendrite-free lithium deposition. The current collector exhibits a reduced nucleation overpotential of 14.2 mV and prolonged cycling life over 400 cycles with average CE >98.5%. The work provides a feasible way to fabricate anode-free lithium metal batteries and enhances the understanding of solid electrolyte interface evolution and Li plating/stripping regulation strategy.

Summary: A new anode structure is proposed in this study, which prevents dendritic Li growth and unstable changes in electrode thickness by plating Li in a fixed-volume space located behind the current collector. This structure ensures stable full-cell operation by preventing Li dendrites from growing into the separator and maintaining a constant electrode thickness.

Summary: In this study, a network of LixCu solid solution alloy nanowires was formed in Ni foam to address the limitations caused by the macropores in porous metal architectures, resulting in a three-component composite anode with exceptional cycling stability. The integration of LixCu nanowires significantly increased the active surface area and induced uniform Li deposition, while the hierarchical architecture further tuned the nucleation and growth behavior of Li, leading to long-term cycling stability even under high current rates.

Summary: In this study, two different coating materials, amorphous Al2O3 and Li3PO4, were demonstrated for Li/NF composite anode via atomic layer deposition (ALD) method. Impedance test shows that Li nucleates easily on Li3PO4 surface compared with NF and Al2O3 surface. Scanning electron microscope (SEM) observation reveals that lithium dendrites were deposited on NF and Al2O3 surface, while no dendrite growth was observed on Li3PO4 surface. Li@Li3PO4@NF anode exhibits better cycling stability and rate capability. Li3PO4 reduces the nucleation overpotential and the surface energy barrier, promoting uniform lithium deposition.

Summary: Anode-free lithium metal batteries (AFMBs) are achieved through the uniform deposition of lithium induced by an Au predeposited three-dimensional (3D) anodic current collector with an ether-based electrolyte. AFMBs using LiFePO4 cathode with Au predeposited 3D anodic current collector (LiFePO4/Au-3D Cu) show better rate performance and longer cycle life compared to two-dimensional (2D) bare copper foil (LiFePO4/2D Cu). This improvement is derived from the regulation of lithium deposition and inhibition of electrolyte decomposition due to the local current density through the predeposition of Au and 3D structure. This study provides a new path to realizing AFMBs.
