Two Advances Point Toward a Cheaper Electric-Car Battery

MIT technology review -- For the roads to start filling up with electric cars, batteries will need to get much cheaper—as much as 80 percent cheaper by some estimates (see “How Improved Batteries Will Make Electric Vehicles Competitive”). Two recent advances that make an experimental type of battery much more practical could lead to such cost savings.

Researchers have for years been working on a type of battery that uses lithium metal in one electrode and sulfur in the other. In theory, this kind of battery could store three to five times as much energy as a conventional lithium-ion battery (see “Revisiting Lithium-Sulfur Batteries”). But lithium metal is highly reactive when exposed to water and can form root-like structures inside batteries over time; these structures can join positive and negative electrodes,

I'm still convinced that eventually EV will need technology that does away with the battery altogether.
E-Squirrel Champion Author Orange County Posts:3,021 Points:823,240 Joined:Feb 2005	Message Posted: Dec 20, 2012 2:17:06 PM Ignore E-Squirrel Report Abuse leeac enthuses: "EV technology continues to advance and EVs are here to stay." Well, the technology will improve over time, but the gains discussed here are just announcements in research papers. These may or may not work out; other technologies may be better. The better technology includes more efficient ICE's as well as improved hybrid designs. Not to mention natural gas....which is already a mature technology.

Like the HDTV... They used to be 1900.00 and now a 54" is 495.00 at WalMart. CD Players started out at about $1200.00 now $29.99.

They cannot get a battery to work so now the want to make sure that we have the potential bomb. Actually this is nothing new. Some Pilots of Cargo Aircraft refuse to load lithium components due to their explosive nature. Just think what this could be like in an auto accident when it is raining or snowing and you EV battery cracks open.
