Chemistry Solid-state chemistry

A newly designed magnesium-tin alloy is bringing magnesium batteries a step closer to reality. The new alloy design improves both stability and magnesium-ion transport inside solid-state batteries, helping address one of the long-standing challenges in next-generation battery technology.

Solid electrolyte particle sizes affect ion pathways

Sometimes the holes, or pores, in the molecular structure of a chemical only appear in the presence of certain conditions or other ‘guest’ molecules. This affects the field of separation—one of the most important processes in industry—but researchers have only just begun to unravel this phenomenon

Solid electrolyte composed of nanoparticles embedded in an amorphous matrix shows high conductivity, formability, and electrochemical stability

Process that can lead to mass synthesis yields solid sulfide electrolyte with world’s highest reported sodium ion conductivity and glass electrolyte

Temperature-controlled, reversible shifting of molecular gear motion in a solid crystal opens new possibilities for material design.

Concave, umbrella-like metal complexes provide space to enable the largest molecular rotor operational in the solid-state.

Researchers succeed in developing a lithium sulfide cathode containing a solid electrolyte with high decomposition resistance, enabling the realization of all-solid-state lithium-sulfur batteries that exceed the energy density of lithium-ion batteries

Lithium ion batteries use liquid electrolytes that have several drawbacks, which can be overcome by all-solid-state lithium secondary batteries (ASSBs). However, it is important to find efficient electrode materials for ASSBs. A research team from Japan has recently developed a novel electrode material for ASSBs by combining lithium sulfate and lithium ruthenate, which results in improved performance. The scientists hope that their novel approach will guide future research and the eventual commercialization of such high-capacity batteries.
