Cellphone batteries to recharge in 15 minutes

Washington: Scientists
are closer to developing a cellphone battery that will take just
15 minutes to recharge and last more than a week.
A team of Northwestern University engineers created an electrode
for lithium-ion batteries, used in cellphones and iPods, that
allows holding a charge up to ten times greater than current
technology.
Batteries with the new electrode also can charge 10 times faster
than current batteries, the journal Advanced Energy Materials
reported.
"We have found a way to extend a new lithium-ion battery's charge
life by ten times," said Harold H. Kung, researcher, a university
statement said.
"Even after 150 charges, which would be one year or more of
operation, the battery is still five times more effective than
lithium-ion batteries on the market today," Kung said.
Researchers combined two chemical engineering approaches to
address two major battery limitations - energy capacity and charge
rate.
Besides better batteries for cellphones and iPods, the technology
could pave the way for more efficient, smaller batteries for
electric cars.
The technology could be seen in the marketplace in the next three
to five years, the researchers said.
