System Bits: April 30


Future batteries could use a graphene sponge Researchers at Sweden’s Chalmers University of Technology devised a porous, sponge-like aerogel, made of reduced-graphene oxide, to serve as a freestanding electrode in the battery cell. This utilization has the potential to advance lithium sulfur batteries, which are said to possess a theoretical energy density about five times greater than lithi... » read more

Recharging The Battery


There are few technologies in today’s cutting-edge technological environment that have a difficult time finding new levels of performance. Battery technology is one of them. With the exception of a few experimental offerings, batteries and their performance metrics are relatively flat. There has been some progress, of course. But when compared to other technologies such as transistors, mem... » read more
