The nanoengineered battery is lightweight, ultra thin, completely flexible, and geared toward meeting the trickiest design and energy requirements of tomorrow’s gadgets, implantable medical equipment, and transportation vehicles.

Along with its ability to function in temperatures up to 300 degrees Fahrenheit and down to 100 below zero, the device is completely integrated and can be printed like paper. The device is also unique in that it can function as both a high-energy battery and a high-power supercapacitor, which are generally separate components in most electrical systems. Another key feature is the capability to use human blood or sweat to help power the battery.

Details of the project are outlined in the paper “Flexible Energy Storage Devices Based on Nanocomposite Paper” published Aug. 13 in the Proceedings of the National Academy of Sciences.

The semblance to paper is no accident: more than 90 percent of the device is made up of cellulose, the same plant cells used in newsprint, loose leaf, lunch bags, and nearly every other type of paper.

I think that's a long shot. Batteries don't provide anything that combustion engines do. A battery is simply a way of storing electricity. All combustion engines do is convert power into electricity on the go, whereas batteries store it. The problem of attaining that energy still remains once you have a battery. Although, having electricity 'mass produced' allows for the use of large scale CO2 reduction using sequestration, solar plants, nuclear, etc. So yes I think this is a great concept IF it works... However, I remember 10 years ago seeing electric cars, in berlin they were going to be 'the next big thing', what happened to that dream???
