Scientists from Hokkaido University have developed a rapid, efficient protocol for cross-coupling reactions, vastly expanding the pool of chemicals that can be used for the synthesis of useful organic compounds.
a novel electrode material for ASSBs
18 Feb 2021
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.
