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: A dendrite-free composite Li metal anode has been achieved using a flexible, freestanding, well-aligned, and highly-lithiophilic MXene paper. The MX@CS paper with a micro-crumpled surface effectively decreases the local current density, guides even Li plating, and suppresses dendritic Li growth. The surface-adsorbed chitosan enhances lithiophilicity and reduces Li nucleation overpotential. The dendrite-free Li morphology of the MX@CS-Li anode results in significantly improved cycling life and high Coulombic efficiency.

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: 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: In this study, N-methylformamide (NMF) was introduced as an organic solvent and its solvation structure was modulated to obtain a stable organic/aqueous hybrid electrolyte for high-voltage Zn batteries. NMF showed excellent stability against Zn metal anodes and reduced the availability of free water molecules by creating numerous hydrogen bonds, allowing for the use of high-voltage Zn||LiMn2O4 batteries. The introduction of NMF prevented hydrogen evolution reaction and promoted the formation of an F-rich solid electrolyte interphase, thereby inhibiting dendrite growth on Zn anodes. The Zn||LiMn2O4 full cells exhibited a high average Coulombic efficiency of 99.7% over 400 cycles.

Summary: This study reports a surface and interface engineering strategy to improve the electrochemical performance of sodium-ion batteries by surface engineering of tin nanorods via N-doped carbon layers (Sn@NC). The authors demonstrate that uniform surface modification can enhance electron and sodium transport kinetics, control alloy pulverization, and form a stable organic-inorganic solid-electrolyte interface (SEI). It is also discovered that the diethylene glycol dimethyl ether electrolyte with optimized Na+ solvation structure can significantly improve reaction kinetics. Consequently, Sn@NC anodes achieve extra-long cycling stability and the full cell exhibits high energy density, excellent high-rate capability, and long cycle life over a wide temperature range.

A specific iron sulfide-based heterostructure (Fe7S8/FeS2/NCNT) with nitrogen-doped carbon nanotubes has been prepared, which demonstrated high reversible capacity, superior rate capability, long-term cycling stability, and outstanding rate capability in different electrolytes. The outstanding performance is mainly attributed to fast sodium-ion diffusion kinetics, high capacitive contribution, and convenient interfacial dynamics.

Summary: In this study, Fe single atom catalysts with sulfur and oxygen functional groups near the atomically dispersed metal centers were prepared, which showed highly efficient oxygen reduction reaction (ORR) performance. The Fe1/NSOC catalyst exhibited a half-wave potential of 0.92 V vs. RHE, surpassing commercial Pt/C (0.88 V), Fe single atoms on N-doped carbon (Fe1/NC, 0.89 V), and most reported nonprecious metal catalysts. Spectroscopic measurements revealed that the presence of sulfur group induced the formation of epoxy groups near the FeN4S2 centers, which not only modulated the electronic structure of Fe single atoms but also participated in the catalytic process to improve the kinetics. Density functional theory calculations demonstrated that the sulfur and epoxy groups engineered the charges of Fe reactive center, facilitating the reductive release of OH* (rate-limiting step) and boosting the overall oxygen reduction efficiency.

Summary: Considering the abundance and low price of sodium, sodium-ion batteries (SIBs) have great potential as an alternative to lithium-based batteries in large-scale energy storage. Layered transition-metal oxides (LTMOs) are regarded as the most promising cathode materials for SIBs due to their high specific capacity and suitable preparation methods. However, their practical utilization is hindered by irreversible structural evolution, slow kinetics, and water sensitivity. Nanoengineering provides an opportunity to address these issues and improve the performance of LTMOs.

Summary: MXenes have been extensively studied for their desirable properties in energy-related applications. However, their practical use has been hindered by slow catalytic reaction kinetics and limited active sites. Surface engineering strategies, including termination engineering, defect engineering, heteroatom doping engineering, secondary material engineering, and extension to MXene analogues, have been investigated to overcome these limitations and enhance the electrocatalytic performance of MXenes. This review summarizes the progress and challenges of MXenes in electrochemical conversion reactions, and emphasizes the need for further understanding and development of MXene-based materials to meet the growing demand for sustainable energy solutions.

Summary: We accelerate the kinetics of acid oxygen reduction reaction (ORR) by using a bi-functional ligand-assisted strategy to pre-control the distance of hetero-metal atoms. The synthesized Fe-Zn diatomic pairs on carbon substrates show outstanding ORR performance with an ultrahigh half-wave potential of 0.86 V vs. RHE in acid electrolyte. The specific distance range of around 3 angstrom between Fe-Zn diatomic pairs is the key to their ultrahigh activity, averaging the interaction between hetero-diatomic active sites and oxygen molecules.
