Summary: In this study, the authors explore a new approach to control gelation mechanisms and patterns using electrochemical-chemical-chemical reactions. By oxidizing the ionic species and/or molecules in solution at a specific electric potential, an intermediate species is generated and reacts with macromolecules to form hydrogels. This method allows for the selection of gelation reactions and control of hydrogel growth rate, and has been demonstrated for patterning hydrogels on gold and flexible ITO foils using a commercial 3D printer.

Summary: This study investigates the electrochemical behavior of titanium niobium oxide (TNO) composites with different percentages of multi-walled carbon nanotubes (MWCNTs). It is found that the addition of MWCNTs significantly improves the electrochemical performance of TNO in terms of initial capacity, rate performance, and rate capability. The cyclic stability of the TNO/MWCNTs composites is also greatly enhanced, with the optimal content of MWCNTs being 3%. The presence of MWCNTs creates a conductive network with good ionic and electrical conductivity, improving the rate performance of the samples and moderating the stresses caused by the intercalation/deintercalation of Li-ions.

Summary: The practical use of lithium metal in high-energy density lithium metal batteries is hindered by the continuous formation of lithium dendrites and irreversibly formed solid electrolyte interfaces (SEIs). By combining operando nuclear magnetic resonance (NMR) spectroscopy with ex situ titration gas chromatography (TGC) and mass spectrometry titration (MST) techniques, a solid foundation for quantifying the evolution of dead lithium metal and SEI separately has been established. The existence of LiH has been identified, causing deviations in the quantification results of dead lithium metal obtained by these techniques. Quantitative studies on the formation of inactive lithium under different operating conditions have revealed a general two-stage failure process for lithium metal.

Summary: Li metal batteries (LMBs) have great potential for next-generation energy storage due to their high energy density and low electrochemical potential. The formation/dissolution of Li metal at the solid-electrolyte interface (SEI) layer has been a major concern, as it leads to battery degradation in practical conditions. In the past decade, in situ electrochemical transmission electron microscopy (EC-TEM) has been developed to track the reactions at the electrode/electrolyte interfaces. This perspective provides a brief introduction to liquid cell development, discusses different configurations of EC-TEM, and focuses on recent advances and future prospects of liquid-cell EC-TEM for LMB research.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
