Ultra Lightweight Laptop

Stanford scientists are incredible. Who could think of plain papers such as batteries and super capacitors? But scientists at Stanford exploit nanotechnology to quickly create ultra-thin, foldable battery and supercapacitors using plain paper. They prepared the ink with carbon nanotubes and nanowires of silver. Silver nanowires are highly conductive storage device. They are covering the paper with the ink of carbon nanotubes and nanowires of silver.

Yi Cui is assistant professor of materials science and engineering. Cui work is published in the journal paper highly conductive energy storage devices. " It is published online in the Proceedings of the National Academy of Sciences. He says, "The company really needs a low cost, a high performance energy storage like batteries and supercapacitors simple."

What is the difference between battery and capacitor? Batteries and load capacitors both store electricity. But capacitors hold it for a shorter duration than normal batteries. However, the capacitors have an advantage. They can store and discharge electricity much faster than a battery.

Cui said on nanomaterials, "These nanomaterials are special. They are one-dimensional structure with very small diameters." The small diameter is very crucial because it helps the ink to stick firmly nanomaterials on fibrous paper. This makes the battery and supercapacitor very durable. The supercapacitor paper can withstand the charge-discharge cycles of 40,000. It's better than the lithium batteries in that order of magnitude is concerned. Cui said that nanomaterials drivers also ideal because they are moving along electricity much more efficiently than ordinary drivers.

Bing Hu is a postdoctoral researcher. He put this theory into practice. He took a small square of plain paper and dipped in ink. The nanotubes are deposited on the surface of the paper. This document can then be responsible for energy and viola! You hold this wonder called stack of paper.

Cui had already experimented with plastic. He created plastic batteries using nano materials. But it concluded that the paper is a better option than plastic. Because a battery of paper is more durable than the plastic like ink on paper glue more strongly. You can test the durability of paper pulp by crushing, folding or soaked in acid or base, is the performance does not deteriorate.

We can conclude that all the piles of paper is more flexible than the plastic one. By using this flexibility, we can operate the battery in many ways. Cui said: "If I want to paint my wall of a storage device of energy required. I can use a brush. "Cui invention can be very beneficial for electric cars or hybrids, because they demand a quick transfer of power. Supercapacitor The paper also enjoys the distinction of surface to volume ratio high. It will be advantageous for hybrid cars.

Peidong Yang is Professor of Chemistry at the University of California-Berkeley. He said: "The technology has the potential to be commercialized within a short time. I do not think it will be limited to energy storage devices. This is potentially a very beautiful, low cost, flexible electrodes for electrical devices. "

Cui provides the greater use of piles of paper in the large-scale storage of electricity on the grid. We all know that the surplus electricity generated at night could be stored in these piles of paper and later used during peak or rush hours. The energy from wind and solar farms can also be stored in these stacks of paper.

Yang stressed its view, "The most important part of this paper is how a simple thing in life - paper - can be used as a substrate for conducting electrodes made functional by a simple process. It nanotechnology.
