Researchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes. Proof-of-concept anodes — the part of the battery that stores lithium ions — built with graphene nanoribbons (GNRs) and tin oxide showed an initial capacity…
University team discovery lets Li-ion batteries charge faster
Editor’s note: Storing power generated by any large-scale source would let utilities spend less fossil fuel and take advantage of renewable energy sources that produce on variable schedules. Hence, the importance of this news. The article comes from Rice University. Researchers at Rice University have refined silicon-based lithium-ion technology by literally crushing their previous work…
Nanocable holds higher capacitance than previous microdesigns
A tiny coaxial nanocable has been created that is much smaller than a human hair. The cable could be used as a transmission line for radio frequency signals or to build next-generation energy storage, a tantalizing prospect for wind and grid developers. The nanocable was developed through recent graphene-research techniques and has a higher capacitance…
