Smartphone won't need batteries in the future

With the ability to fully charged in seconds, smaller size and the ability to use a few days, the application of energy from the silicon into smartphones is very promising.

 

 

Battery current is still one of the problems related to electronic devices received the most complaints. Not enough capacity to meet user needs, so long charging time, battery rapid heating and great weight? Have you ever thought about the prospect of a device that does not need battery energy by operating the machine has been integrated directly into the device yet?

 

 

Find out a more efficient source of energy for mobile devices is a problem a lot of research labs focused on solving the world.

 

 

For the first time in history, scientists have successfully created an energy source from silicon - the material component of computer chips and solar particles. Accordingly, this discovery could open up the future of mobile devices that will contain energy without batteries. Super capacitors can be fully charged silicon within a few seconds and can operate the phone in a few days.

 

This is the work of a team of engineers at the University of Vanderbilt, and it could open up a new future for smartphones and other mobile devices.

 

 

 

 

 

 
Specifically, unlike conventional batteries, capacitors contain energy above by arranging the ions on a silicon surface with holes instead of the energy contained in the chemical reaction. However, because silicon can react with some chemicals in the electrolyte produces electric charge, so engineers were conducting coating is a layer of graphene. Flakes were not only protective but also increased silicon power density significantly. As a result, the new capacitors will be able to store more energy with the charging time is reduced to just in seconds. All of the above technologies will be encapsulated in a tiny silicon chip.

 

 

 

Superior energy density (red region) of the chip is new energy research.

It is known that the current supercapacitors are usually made ​​of carbon and silicon in the idea utilize this field is still relatively new and groundbreaking. Still, to this technology can step out the mass market, there are still many problems to be solved engineers. However, we may also excited by the future, most likely the phone will no longer use the more cumbersome batteries instead are tiny chip energy, creating space for flexibility other conditions or significantly reduced weight equipment.
