PostSubject: How National Security Hinges on Better Lithium Batteries.   Tue Oct 11, 2011 2:13 pm

Lithium spontaneously combusts inside air, yet the battery in your computer梐nd in either of the stacks in the new variety of electric vehicles梚s made from that. Lithium even burns during water, which is too bad must be lithium-water battery could get both cheap and successful. Now battery-maker PolyPlus claims to experience created such a electric by encasing the lithium from a special membrane that will allow for it to pass cost without melting down.

"Lithium is normally explosive in water, inches Arun Majumdar, director for the Advanced Research Projects Agency朎nergy, or possibly ARPA杄, which is funding PolyPlus's development effort, noted inside the agency's second annual office meeting March 1. By ensconcing the lithium around the membrane's seal, the PolyPlus battery reacts safely with all the oxygen dissolved in the water and delivers even though 1, 300 watt-hours every kilogram of electricity. "This will be a fish, but it's a really battery. "



PolyPlus is one amongst several better battery-makers this ARPA杄 is funding, all wishing to improve upon a basic lithium ion battery's nearly 400 watt-hours per kilogram梩he cause all-electric cars don't have long distance range of an traditional automobile. The program梔ubbed BEEST, for Batteries for Energy Storage in Transportation梙as funded 10 projects in every, ranging from rechargeable energy composed entirely of solid materials to high-energy denseness capacitors. "Just like Intel Inside of, I hope you have BEEST inside your electric cars at some point, " Majumdar said.

Reinventing the battery is techniques available today to both reduce usage of oil and bring manufacturing jobs back to the U. S., Secretary of one's Steven Chu told conference attendees. John Goodenough inside the University of Texas conceived the lithium ion battery used today梑ut Japanese and Korean companies now produce just about the most globally. "Just because we lost the lead doesn't mean we can't stimulate it back, " Chu mentioned, referencing battery technology with Argonne National Laboratory at this point being licensed by Overall Motors and LG.

Really, better batteries梠r finding an effective way to keep lithium from combusting with air, like PolyPlus and the Missouri University of Science and Technology making the effort do梒an result in minimizing the demand for brought in oil that sends $1 billion per day abroad, largely to Nova scotia, Middle Eastern countries and Venezuela. "Our national security could be very dependent on energy stability, " Chu noted. "Energy we create in your home is wealth creation in the home. "
