Nanotechnology Advancing Battery Technology


Welcome to the Collaborative Revolution!

These are the kinds of advances we need to see if green renewable energy is to ever have a shot at competing with fossil fuels as a cost effective energy alternative. Those of you who follow the blog know I'm a bit enamored with nanotechnology and the more I read the cooler it becomes. The article linked below explains how a research team has enhanced the traditional lithium battery.

"To create the layered carbon nanotubes, the researchers dipped a base material repeatedly into a solution loaded with carbon nanotubes. The layers then built themselves up like a candle. To make the carbon nanotubes self-assemble onto the base material and stick together in even sheets, the scientists alternately charged them with positive and negative organic compounds. According to the researchers, the method could be adapted for spraying on the nanotubes which would then make the batteries ready for mass production on an assembly line."

The other cool thing is they recharged the battery a 1,000 times with no appreciable impact on its ability to hold the charge.

Hat tip to Glenn Reynolds at Instapundit.

As Glenn would say, "Faster please!"
