Nanotubes in batteries
Elsewhere in nanotube news, Nanoexa has announced 3kw / kg energy density in a lithium ion battery. The article is short on perspective with regard to that figure (usually energy density is measured in kilowatt hours, not kilowatts), but a helpful autobloggreen reader cites their press release as claiming “50% higher energy density than existing lithium ion cells.” Not bad! Here’s the press release (pdf).
