Batteries of the future: current in a piece of paper

Researchers at Rensselaer Polytechnic Institute in the U.S. have developed a new energy storage device that is easy to confuse at first sight with a piece of black paper. The "nano-battery" is not only extremely light and thin, but also flexible and thus could enable completely new equipment designs.

The paper batteries could, for example in implantable medical Devices be installed or much better than previously housed in vehicles. The DELL XPS M1530 batteryoperate at temperatures up to 150 degrees Celsius and to minus 70 degrees and can also be printed like paper. Another case the battery do not need, so they could be moved into the smallest niches.

The energy storage have another advantage: you can not just as a high-capacity battery, but also as a condenser to work - in most electrical Systems these are currently two components. But the most amazing ability is that it can be even used without isolation in human blood.

The proximity to paper is no accident: more than 90 percent of the Nano batteries are made of cellulose. The Rensselaer researchers soaked this paper with aligned carbon nanotubes, which are responsible for the black color. The nanotubes act as electrodes and allow the design to be conductive. The electrolyte is fed into the paper. The energy transfer can be done slowly and relatively evenly over a long period such as a HP Pavilion DV5 Battery or in a flash as in a capacitor.

The paper batteries can be rolled, twisted, folded or cut into any shape without losing their Efficiency or lose mechanical integrity. The nano-papers can be stacked as well as their white counterparts to increase the total capacity.

The researchers used an ionic liquid as the electrolyte, ultimately, a liquid salt, which contains mainly ions. The liquid contains no water. The HP Pavilion DV7 Battery can in the given temperature range can therefore neither freeze nor evaporate portions thereof.

The components of the Dell Latitude E4300 battery are not expensive, but so far the team has not yet developed a mass production capabilities. The goal is to machines that manufacture the paper batteries as ordinary newspaper is printed. A patent application has been filed. Now you are working on increasing the efficiency of the batteries and the Development manufacturing techniques.

Basic data of electrical batteries Papp was not yet known. Also how it behaves with the durability of the Dell XPS M1730 battery or when first Applications be expected in practice, has not been disclosed.
