Sulfide solid electrolytes (SEs) with high Li-ion conductivities (σ<sub>ion</sub>) and soft mechanical properties have limited applications in wet casting processes for commercial all-solid-state batteries (ASSBs) because of their inherent atmospheric and chemical instabilities. In this study, we fabricated sulfide SEs with a novel core-shell structure via environmental mechanical alloying, while providing sufficient control of the partial pressure of oxygen. This powder possesses notable atmosp
Metal–fluoride possesses a high potential as new high-performance water oxidation catalysts due to a highly polarized electronic configuration. However, low conductivity, related to high iconicity in metal–fluorine bonds, and instability of metal–fluoride in alkaline solution act as major roadblocks for using metal–fluoride as a highly efficient electrocatalyst. Here, we first disclose a novel strategy to design the electrochemically active and stable metal–fluoride electrocatalysts, nickel–coba
Charge separation is the most important factor in determining the photocatalytic activity of a 2D/2D heterostructure. Despite the exclusive advantages of 2D/2D heterostructure semiconductor systems such as large surface/volume ratios, their use in photocatalysis is limited due to the low efficiency of charge separation and high recombination rates. As a remedy for the weak interlayer binding and low carrier transport efficiency in 2D/2D heterojunctioned semiconductors, we suggested an impurity i
