Comments for Carbon Nanotubes Could Be Secret to Greater EV Range at http://www.ecogeek.org , comment 1 to 3 out of 3 comments http://www.ecogeek.org Sun, 19 May 2013 16:57:53 +0100 FeedCreator 1.7.3 http://www.ecogeek.org/power-storage/3196-carbon-nanotubes-could-be-secret-to-greater-ev-ran#comment-40417 I think greater [i]capacity[/i] is what the article (second page) is stating: "The more total lithium the battery can store, the greater its total energy storage capacity. The faster the ions can move out of one electrode and into the other, the greater its power. In work published this week in the journal Nature Nanotechnology, the MIT group showed that lithium ions in a battery electrolyte react with oxygen-containing chemical groups on the surface of the carbon nanotubes in the film. Because of the huge surface area and porous structure of the nanotube electrodes, there are many places for the ions to react, and they can travel in and out rapidly, which gives the nanotube battery [b]high energy capacity and power[/b], says Shao-Horn." - m Thu, 22 Jul 2010 05:34:51 +0100 http://www.ecogeek.org/power-storage/3196-carbon-nanotubes-could-be-secret-to-greater-ev-ran#comment-39890 Great article! Here's another EV story: http://www.ecoseed.org/en/general-green-news/green-topics/green-transportation/electric-vehicles/7452 - Saar Wed, 23 Jun 2010 04:31:24 +0100 http://www.ecogeek.org/power-storage/3196-carbon-nanotubes-could-be-secret-to-greater-ev-ran#comment-39862 Hi, [quote]could lead to much greater range in electric vehicles[/quote] Thats an incorrect conclusion. [quote]The carbon nanotube electrodes enable lithium ion batteries to deliver ten times more [b]power[/b] than a conventional battery and store five times more [b]energy[/b] than a conventional ultracapacitor.[/quote] Power delivery and energy capacity are not the same. Current capacitors have excellent power delivery but poor energy capacity. If this technology had five times the energy capacity of a conventional battery that conclusion would be correct. - Mitch Tue, 22 Jun 2010 14:39:46 +0100
