The use of graphene seems to be emerging as one of the ways forward for new lithium-ion battery designs. If you remember, SiNode Systems is working with anodes that use graphene to build a high-capacity, high-performance lithium-ion battery. It turns out Rice University researchers also are experimenting with graphene--in the form of graphene nanoribbons (GNRs)--to achieve a similar effect.
A Rice research team--including chemistry, engineering, and computer science professor James Tour and postdoctoral research Jian Lin--has successfully created proof-of-concept anodes that are capable of more capacity than typical battery anodes by creating them out of GNRs and tin oxide. Typical lithium-ion battery anodes, or the part of the battery that stores lithium ions, are made primarily of tin oxide and graphite. Click to read the rest of this story on DesignNews.
Are there any good examples of any mature products utilizing nanotubes or ribbons - in electronics - currently in production? Not to be a pessimist, as I really want to see their advantages used in electronics, but there is a big difference between mixing them into products for 20%-30% strength gains and making them work well in electrical applications.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
