Summary: It is demonstrated that sodium formate (HCOONa), a component of the solid electrolyte interphase (SEI), can be used to design high-performance artificial SEI layers, which effectively suppress sodium dendrite formation and side reactions with the electrolyte. A single molecular layer of HCOONa formed on a commercial copper current collector extends the lifespan of anode-free Cu|Na3V2(PO4)(3) battery to 400 cycles, representing the longest reported cycle lifetime in anode-free NMBs.

Summary: Due to its high theoretical special capacity, low cost, and low redox potential, sodium (Na) metal is considered as an ideal anode material for high-energy-density Na metal batteries. However, dendrite formation and unstable interface between Na and electrolyte hinder its practical application. In this study, a Zn coating on the Na metal surface was successfully fabricated through a simple chemical method, which improved the corrosion resistance and led to a uniform Na deposition. The Zn-coated Na showed stable cycling performance and high capacity in symmetric cells. When combined with Na3V2(PO4)(3) cathode, full cells with Zn-coated Na demonstrated good cycling stability and rate capability.

Summary: Lithium-sulfur (Li-S) batteries, with high energy densities and abundance of sulfur, are considered as promising candidates for high-energy batteries. However, the traditional carbon hosts used in Li-S batteries have limitations in adsorbing Li-polysulfides and facilitating redox kinetics, resulting in low capacity and rate capability. This review highlights the use of non-carbon hosts in Li-S batteries, which show improved sulfur utilization and stabilizing Li metal anodes. The challenges and prospects of implementing non-carbon hosts for practical carbon-free Li-S batteries are also discussed.

Summary: Sodium metal (Na) anodes, with high capacity and low electrochemical potential, are considered the most promising anode for high-energy-density sodium batteries. However, uncontrolled Na dendrite growth and unstable solid electrolyte interphase layer (SEI) formation during cycling have led to poor coulombic efficiency and shorter lifespan. This study explores a series of Na-ion conductive alloy-type protective interfaces (Na-In, Na-Bi, Na-Zn, Na-Sn) as artificial SEI layers to address these issues.

Partial copper-coated Pd nanocubes can reduce 95% of NO3- and have 89% selectivity for NO2- reduction over 20 cycles (80 h). Complete copper-covered Pd nanocubes can reduce about 99% of NO3- and selectively reduce NO2- to NH4+ with a 70% selectivity over 20 cycles (80 h).
