Fuel cells on sugar - the future of batteries for mobile phones

Researchers elated idea biobatareek - devices capable of generating electricity on the basis of normal biological processes. Most of them are not able to produce large amounts of energy, but recently, scientists have developed a prototype that can be the easiest and powerful model of the battery all that can be found in today's portable electronic devices, including smartphones.
In the body of the sugar is converted into energy in a process called metabolism, during which it decomposes into carbon dioxide and water, thereby emitting electrons.Biobatareyki produce energy by means of such a conversion process, but only by trapping the electrons generated in the disintegration of sugar, and are similar to those used in instruments that have an organism. Since biobatareykah subject to the samebiological materials , they are non-toxic and renewable source of electricity, which makes them an attractive alternative to traditional batteries, require of metals and chemicals.

Percival Zhang and Zhiguang Zhu, researchers from the Polytechnic University of Virginia, USA, have developed a new biobatareyku with higher power output per unit mass than conventional lithium-ion batteries used in most electronic devices.
New biobatareyka fully converts sugar into energy, and that means better performance than the one that showed the previous biobatareyki, and their charge is more than the lithium-ion counterparts.
"For example, with a conventional battery, your phone can survive a day in the future when the battery is based on sugar, it will work on a single charge 10 days" - emphasizes Zhiguang Zhu. 
New biobatareyka owes such efficiency innovative system enzyme protein nature, provoking a reaction. The system utilizes two active enzyme, which release two pairs of electrons from glucose, whereas 10 other enzymes contribute to the reaction inside biobatareyki restart. When the reaction is resumed active enzymes release four more electrons. After six cycles biobatareyka uses all the energy contained in the sugar molecule, as well as carbon dioxide and water .
Previously biobatareyki can extract only one sixth of the amount of energy that provides a new model, since they do not use such an enzyme system. Upon receipt of a larger number of electrons per unit weight of sugar increases its energy density.
One of the main advantages of this biobatareyki is that at full conversion of sugar to energy use less enzyme than in the body, making the system more stable.
Independent experts say that scientists were able to develop a very economical cycle enzyme, since the system is capable of releasing all the electrons, using a minimum ofenzymes .
But although the new enzyme system represents a significant advancement in technology biobatareek, there are a number of obstacles that must be overcome before the device will be released on the broader market.
Thus, according to researchers at the existing, non-optimized model output is still too low for many devices, and the period of operation element is too short, and it still can not be recharged.
However, they believe that such complexity - it is solely an engineering aspect of the technology. Scientists believe that they can fix them at the earliest stages of a new company to mass produce biobatareek on sugar.
