Japanese engineers develop new super-thin battery with rapid recharge capabilities
by Mike Adams, the Health Ranger, NaturalNews Editor
Japan's NEC Corp. claims that company engineers have developed a revolutionary "organic radical battery" that can be recharged in 30 seconds and is extremely thin at less than a millimeter in thickness.
Engineers at Japan's NEC Corp. have developed a flexible battery that is less than a millimeter thick and can be charged in half a minute, the company said.
The battery has been designed for use in applications such as active radio frequency identification (RFID) cards and could provide enough power to keep such cards running for several weeks before requiring a recharge, said Yoshimi Kubo, chief manager of fuel cell and battery research at NEC's fundamental and environmental research laboratories yesterday.

The battery measures about 4 centimeters square and has been fitted into a card that's about the same size as an identification or credit card.
After a charge, it can keep an LED embedded in the card lighted for about 20 minutes before requiring a recharge.
Such thin batteries are important for active-type RFID cards.
Most RFID cards or tags are passive devices that aren't capable of transmitting data on their own and work when brought into proximity with a radio field from a tag reader.
NEC said it has no plans for commercial production of the device or an estimate of how much it would cost at such a time as production begins.
Because the battery is capable of delivering a large amount of power in a short period, NEC demonstrated it being used to power a PC for about 15 seconds, which is enough time for the PC to back up important data and shut down properly.
Like the prototype on show this week, NEC didn't have any immediate commercialization plans for the technology.
