Japanese company NEC claims to be giving long battery charge times the boot with the launch of its new super thin battery. NEC claims its new organic radical battery (ORB) can be charged in 30 seconds flat. The organic radial properties allow the internal electrode reactions to take place very quickly, as the supporting salts travel through gel state polymers without much resistance. In effect, this means there’s very little resistance to the charging reaction and this allows the battery to be fully charged faster than ordinary batteries. The 300-micron thick battery uses a flexible polymer as its cathode and is slim enough to be integrated in recognition (intelligent) paper and smart cards. NEC claims the battery is environmentally friendly, as it lacks harmful chemicals such as cadmium, lead and mercury, which are present in other battery types currently used in mobile phones and laptops. Samples of the new batteries are currently being displayed at iEXPO 2005 in Tokyo, Japan. NEC has not yet revealed when it will begin putting the batteries into mass production for commercial use. In the region, Sony recently unveiled its Network Walkman NW-E505 MP3 player series, which it claims lets users play songs for three hours with a three-minute charge. However, when the WinLabs team reviewed the player, it was revealed that a three-minute charge only provided a little over two hours of playback. Meanwhile over in Japan, Canon is also working on a fuel cell technology, which it claims is an environmentally friendly replacement for lithium batteries. The firm also believes the technology will be able to increase battery life considerably. However, in contrast to NEC, Canon’s new technology will mostly be included in slightly larger devices such as digital cameras and compact photos printers.
