Summary: The study demonstrates that the Mn1-xVxP solid solution exhibits excellent high-rate cycling performance at high current density, thanks to the synergistic effects of two reaction mechanisms. The homogeneous substitution of vanadium ions in the solid solution enables the alloying/insertion hybrid electrochemical reaction to proceed effectively, reducing the rate of volume change and preventing pulverization and agglomeration of alloying reaction-type Li-Mn-P crystallites during cycling.

Summary: This study investigates the impact of dispersion forces on MO6S8 chevrel phase intercalation compounds. Dispersion forces have only a slight effect on the lattice spacing of the chevrel phase, but have a significant impact on the insertion voltage and charge carrier mobility. Additionally, the diffusion barriers of charge carriers in the chevrel phase scale linearly with ion size, regardless of the ion charge.

Summary: The new high-pressure die-cast (HPDC) Mg-4Al-3La-1Ca-0.3Mn (ALaX431) alloy achieves higher strength than existing HPDC Mg alloys, mainly due to the formation of fine grained structure, semi-continuous reticular structure, and nanoscale precipitates. Consequently, it has great potential for wide application.

Summary: Rechargeable aluminum batteries have potential as large-scale energy storage technologies due to their abundance, high theoretical capacity, and safety. Researchers have developed a prototype cell with low discharge-charge hysteresis, ultra-flat discharge plateau, and exceptional cycle stability. The intercalation-extraction mechanism of the Al-Mo6Se8 system has been investigated, revealing a reversible intercalation reaction from Mo6Se8 to Al4/3Mo6Se8. The stable electrochemical performance and clear intercalation mechanism provide an alternative for beyond-lithium battery technologies.

Summary: The use of cerium-based conversion coating has been shown to effectively improve the corrosion resistance of squeeze-cast Mg-4wt%Y alloy in a salt solution, with significant reduction in corrosion rate observed compared to the base alloy. The corrosion mechanism predominantly involves pitting corrosion around the second phase due to micro-galvanic coupling between alpha-Mg phase and Mg24Y5 precipitates.

Summary: The aim of this study is to investigate the effect of heat treatment on the microstructure, mechanical, and corrosion properties of Al 319.0 alloy. The results show that heat treatment leads to the dissolution of certain phases and changes in the morphology of others. Treated alloy specimens exhibit improved mechanical properties at ambient temperatures, but a reduction in performance at higher temperatures due to thermal softening. In terms of corrosion resistance, the heat-treated alloy demonstrates superior performance compared to the as-cast alloy, thanks to the presence of protective precipitates and a finer microstructure.
