Rechargeable magnesium batteries have received increasing interest because of the prominent advan-tages,including high security,low cost,and high energy density.The development of rechargeable mag-nesium batteries is hindered by the sluggish Mg2+ ion diffusion kinetics,which makes the exploration of high-performance cathode materials a problem.Recently researchers have exploited various selenium-based cathodes for rechargeable magnesium batteries.Herein,we have critically reviewed these advance-ments,studying different types of reaction mechanisms and analyzing the electrochemical performance of cathode materials in rechargeable magnesium batteries.Besides,as key materials for rechargeable mag-nesium batteries,the exploit and optimization of electrolytes are discussed as well,including the selec-tion of reagents,the effect of Li salts,and the compatibility between electrodes and electrolytes.Finally,promising directions are proposed for future rechargeable magnesium batteries based on selenium-based cathode materials.

The influence of laminar flow on the corrosion of pure zinc (Zn) and cell response was investigated and compared with the static measurements.The results revealed that laminar flow accelerated the corrosion and enhanced the localized corrosion of pure Zn.
The development of ultrastrong maraging stainless steels (MSSs) is always in high demand.However,tra-ditional high-strength MSSs generally exhibit early plastic instability with a low uniform strain since the precipitated nanoparticles are non-coherent wi
