Molecularly engineered COF-graphene interlayer boosts Li-S battery performance
Researchers have developed a new molecularly engineered COF-graphene interface called TUS-44 to improve the performance of lithium-sulfur batteries. This material addresses issues like polysulfide shuttling and slow conversion kinetics, which have historically limited the lifespan and efficiency of these batteries.
Why it matters
Advancements in battery technology are critical for the development of high-capacity, long-lasting energy storage solutions for electric vehicles and renewable energy grids.
Researchers from Lanzhou University, Tohoku University and SRM University have developed a molecularly engineered covalent organic framework (COF)-graphene interface that addresses two persistent challenges in lithium-sulfur (Li-S) batteries: polysulfide shuttling and sluggish conversion kinetics.
