Summary: This study presents a method to induce uniform nucleation of lithium on copper substrates using high current density, which improves the density and uniformity of lithium electrodeposition. The as-obtained Li seeds with small and uniform size cover the copper surface effectively, and the LiF-rich solid electrolyte interface inhibits dendritic lithium formation, leading to significant improvement in cycling stability of the battery.

Summary: A reliable and dendrite-free Li-metal anode has been fabricated through chemical confinement. The configuration consists of uniformly distributed LiZn and Li2O phases, where the lithiophilic Li2O phases with favorable Li diffusion barrier guarantee preferential Li nucleation and prevent Li diffusion to uneven charge accumulation sites. The electron-conductive LiZn phases ensure efficient electron transfer and enable uniform Li deposition. The as-prepared Li-metal anode demonstrates low overpotential, preferable cycling stability, and rate capability.

Summary: In this study, the use of LSCF oxide as an artificial interphase layer for uniform Li deposition in Li metal batteries was proposed. The PCOVs from LSCF can act as a natural electrostatic shield for Li deposition, preventing dendrite growth. Additionally, LSCF can firmly affix to the copper foil surface, facilitating Li ion transport. Experimental results showed that the LSCF-decorated copper foil exhibited stable electrochemical performance during cycling.

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.

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, 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: In recent years, research on Li metal anodes as an alternative to graphite anodes in Li-ion batteries has gained significant attention due to its potential in boosting the energy density of lithium batteries. However, the practical use of Li metal anodes has been hindered by issues of unstable Li deposition and poor cyclability. This article discusses recent advances in understanding the mechanisms of Li deposition/dissolution and solid-electrolyte-interphase (SEI) formation through advanced characterization techniques and simulation methods. The limitations and open questions in these processes are also addressed, along with perspectives on future research and potential methods for obtaining new insights.

Summary: The elucidation of lithium ion transport pathways through a solid electrolyte separator is important for the development of all-solid-state batteries. Neutron imaging was performed on an all-solid-state lithium-sulfur battery using an increased Li-6 content in the anode. This allowed for differentiation between the mobile lithium ions diffusing through the cell and those initially located in the solid electrolyte, and demonstrated the lithium ion diffusion through the cell and the distribution of trapped lithium ions in charged and discharged states.

Summary: In this study, neutron imaging was used to visualize and study invasion phenomena in fibrous porous transport layers (PTLs) of titanium felt under different flow conditions of gas and liquid phase. The invasion process was characterized by counter-current flow of water and air with joint imbibition and drainage processes. Neutron radiography and tomography were used to visualize the dynamics and study the static gas-liquid distributions. The results showed that the invasion occurred in repeated imbibition/drainage cycles, with frequencies depending on the flow conditions and the PTL structure.

Summary: The low rate-capability of solid-state lithium-sulfur batteries is a major obstacle to their development. Neutron imaging has revealed that sluggish ion transport within the composite cathode is the main reason for this limitation. Furthermore, concentrated lithium near the current collector, discovered through state-of-charge-dependent tomography, indicates a previously overlooked loss mechanism caused by sluggish ion transport.

Summary: By employing thermal-induced in situ polymerization of lithium perfluoropinacolatoaluminate, a novel interface-compatible and safe single-ion conductive 3D polymer electrolyte (3D-SIPE-LiFPA) has been developed.
