NEC Corp has developed a battery that can be recharged only in 30 seconds, company sources said. Called an organic radical battery, it can be recharged to the same level of power as that stored in nickel-hydrogen cells, which are widely used in digital cameras, portable MD players and other electronic devices.

It takes only about 30 seconds to recharge the battery enough to allow 80 hours of continuous operation of an MD player, compared with around an hour needed by conventional rechargeables, the company claims.

Because of its ability to recharge faster, the new battery, which stores power in a special resin, is expected to make radio-controlled toy cars, shavers and other products much more convenient to use.

The battery can also discharge power in a short time, making it useful in applications requiring a large amount of power.

NEC believes the battery can be used as an emergency power source for computers in case of blackouts as well as in hybrid cars driven by a gasoline engine and electric motor.
