<H1 class=title><FONT size=4>New high-performance lithium-ion battery 'top
candidate' for electric cars</FONT></H1>
<H2 class=subtitle></H2>
<P>Scientists are reporting development of an advanced lithium-ion battery that
is ideal for powering the electric vehicles now making their way into dealer
showrooms. The new battery can store large amounts of energy in a small space
and has a high rate capacity, meaning it can provide current even in extreme
temperatures. A report on this innovation appears in ACS' Journal of the
American Chemical Society.</P>
<P>Bruno Scrosati, Yang-Kook Sun, and colleagues point out that consumers have a
great desire for electric vehicles, given the shortage and expense of petroleum.
But a typical hybrid car can only go short distances on electricity alone, and
they hold less charge in very hot or very cold temperatures. With the government
push to have one million electric cars on U.S. roads by 2015, the pressure to
solve these problems is high. To make electric vehicles a more realistic
alternative to gas-powered automobiles, the researchers realized that an
improved battery was needed.</P>
<P>The scientists developed a high-capacity, nanostructured, tin-carbon anode,
or positive electrode, and a high-voltage, lithium-ion cathode, the negative
electrode. When the two parts are put together, the result is a high-performance
battery with a high energy density and rate capacity. "On the basis of the
performance demonstrated here, this battery is a top candidate for powering
sustainable vehicles," the researchers say. </P>
