Toshiba's New Battery Recharges In One
Minute March 30, 2020
Toshiba announces a new
lithium-ion battery -- the type used in virtually all laptops -- that
recharges 60 times faster than current batteries.
Toshiba on Tuesday announced a
new lithium-ion battery -- the type used in virtually all laptops -- that
recharges 60 times faster than current batteries and loses less than one
percent of its capacity after 1,000 recharges.
The new battery can be refilled to 80 percent of capacity in one minute,
Toshiba claimed, significantly less time than the one-to-four hours needed

batteries now in use.
According to Toshiba, the
secret's in the negative electrode. "Nano-particles prevent organic liquid
electrolytes from reducing during battery recharging," said Toshiba in a
statement. "The nano-particles quickly absorb and store vast amount of
lithium ions, without causing any deterioration in the electrode."
The Japanese technology giant
said that it expected to put the new batteries into play in 2006, initially
in automotive and industrial applications. One use, Toshiba said, would be
within hybrid vehicles, which store power generated when, for instance, the
Toshiba said it would move the
new batteries into consumer electronics applications, such as laptops and
cameras, at a later date.
Fuel Cells Could Be Next Power Source For Laptops May 12, 2020
ABI Research says some Japanese
companies are pumping millions into R&D, and that by 2012, as many as 15% of
laptops could use fuel cells for power.

Japanese technology companies are pumping hundreds of millions of dollars
into R&D on fuel cells to power laptops, PDAs, and phones, a research firm
said Wednesday, in an effort to keep up with the insatiable power demand of
Fuel-cell technology, developed by NASA during the opening years of the
space program, creates electricity from chemical reactions between
fuels--such as hydrogen or methanol--and an oxidant. They've been touted as
the power source for everything from future automobiles to in-home
generators that take a house off the grid.
By 2012, said Atakan Ozbek, director of energy research at ABI Research, 10%
to 15% of laptops sold worldwide will rely on micro fuel cells, not
batteries, for their power. "Even though processor vendors like Intel and
power management manufacturers such as Texas Instruments are giving us
solutions and better chips for longer battery life," said Ozbek, "device
makers are continually adding functionality that means more energy is
needed. That trend is never going to change."
Over the long term, he said, battery technology just isn't up to the
chore--and fuel cells may provide a way to extend power lifespan.
"With new applications, whether it's 3G or Wi-Fi or DVD, we need more
power," Ozbek said. "We need six to eight, or eight to 10 hours of
continuous power, something we just can't get from the current technology."
Prime candidates for longer-life power supplies in portable devices, he
said, include mobile workers and the military.
Micro fuel cells as small as a disposable cigarette lighter could be the
answer. Using an 80-20 mix of water and methanol, they promise to deliver
enough power to keep the next several generations of laptops and PDAs
running for a longer time. Today's laptops draw 10 to 15 watts of power, but
future models will be even hungrier, needing 20 to 25 watts. Micro fuel
cells focus on providing up to 100 watts of power.
Japanese firms such as Samsung, Toshiba, and Sony are among those investing
in fuel cell technologies; according to Ozbek, they're in a better position
to bring their work to fruition. "On one level, these firms make chips,' he
said. "On another they make components. And they make complete products.
They know where they're going, and this gives them a competitive edge in the
Although his study looked far down the road, Ozbek said to expect
small-sized trials of fuel cell-powered laptops as early as 2005. He
projects that about 2,000 units will be put into play next year, used almost
exclusively within the Japanese companies betting heavily on fuel cells.
The fuel cells themselves are disposable--not rechargeable like today's
lithium-ion batteries in laptops--but that's not an insurmountable
challenge, said Ozbek. Distribution channels are already in place for such
items, and may take the form of agreements with major firms such as Bic and
Gillette, which know how to sell disposable products. Users might balk at
the idea of replacing, rather than recharging, but Ozbek pointed to the
success of similar models, such as ink-jet cartridges, as a harbinger.
But there are many hurdles that haven't yet been faced. "Not everything is a
bed of roses," said Ozbek. He cited environmental concerns, the lack of
standards, and the need to come up with regulations on shipping fuel cells
similar to those now in place for batteries and disposable lighters.
"What's needed is a couple of million [micro fuel cells] out there," Ozbek
said. "Once that happens, manufacturers can increase capacity in a very
