Japan's NEC has developed a thin, foldable battery to be used in cards or clothes, leading to new possibilities such as people walking through ticket gates with fare passes in their pockets. The 0.3-millimeter (0.012-inch) thick battery can support tens of thousands of signal transmissions on a single charge and can be recharged in less than 30 seconds, NEC said.
The battery "will be used extensively in the future to power all kinds" of gadgets ranging from electronic paper to tags that trace retail goods in real-time, it said.
It is "bringing us closer to a ubiquitous networked society by allowing access to the network anytime, anywhere," an NEC statement said.
It will open the way for small wearable computers, such as ticket cards that can be attached to a person's clothes, it said.
Can it keep us warm?
Wake up, Neo.
Probably will assist in building less detectable bombs, as well.
That was my first thought before even clicking the link to read the article. Paper thin batteries to power electric blasting caps on a bomb vest.
or in a letter.
I personally don't like the idea of having a "paper-thin" battery strapped to be. What would happen if the contents seaped onto your skin?
Probably not. NEC's website said that its energy capacity is 1 milliwatt hour per square centimeter. So one of these flat batteries the size of a credit card would have less than 50 mWh of capacity.
Compare that to a AAA battery with about 1800 mWh capacity or even a common 2032 lithium battery with 675 mWh.
Can a folding car be far off? ala George Jetson?.......
Re Post 9 ... isn't that the display at the Hilton in Vegas ???
Any advance in battery technology is much appreciated.
I haven't the slightest clue. Actually, when I found the picture on google, I didn't even notice what the background was.
