Like everyone else, I have far too many battery powered devices and not enough long lasting, reliable batteries! As a result, I am quite interested whenever I hear about some sort of advance in the battery market, like the new paper thin batteries developed by NEC:
NEC has debuted some ultra-thin and flexible quick charging batteries named ORB, for Organic Radical Battery. We’re having a hard time deciding what is the coolest part about these; their 0.3mm thickness that allows them to be flexible, or the fact that they can be recharged in about 30 seconds. The organic radical materials inside the battery are in an “electrolyte-permeated gel state,” which is supposedly about halfway between a solid and a liquid. This helps ions make a smooth move (no, the other one), reducing resistance, allowing the batteries to charge faster. 1 square centimeter will give you about 1 miliwatt hour.
These batteries will be useful for things like RFID tags, electronic paper, and wearable computers. If they can boost the power though, maybe they’d make their way into normal laptops and other small computing devices. Even something like the iPod Nano would benefit from super thin batteries!
