Det här låter riktigt coolt. Undrans hur lånd tid det kommer att ta innan man kan köpa sådana batterier till sin mobil eller laptop?

April 2, 2004 (TOKYO) -- 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.
The battery can also discharge power in a short time, making it useful in applications requiring a large amount of power.
