We've seen countless attempts to build a better lithium-ion battery, but there's been far fewer research efforts devoted solely to figuring out why lithium-ion batteries don't last longer. A team of scientists at the Pacific Northwest National Laboratory have been doing just that, however, and they're now sharing some of their findings.

Researchers at the Fraunhofer Institute in Germany have managed to create a tiny battery, small enough to be easily "printed" and manufactured. 
 
The battery, which weighs only a few grams, could find use in disposable receipts, cards and other handy application. It is also pretty cheap to manufacture. As the anode and the cathode material gets "used up" as it drains, it's easily disposable as well. It's just a millimeter thick and runs at 1.5 volts. It is also claimed to be quite environmentally friendly, as it does not use mercury. 
 
Products running using this battery can be expected to see production by next year.
