Since the introduction of electric and hybrid vehicles topics

such as energy storage and batteries become increasingly important and interesting. That shows in the growing number of scientific
publications and company foundations in this segment. Over the last 
years, several companies have developed nanotechnology applications, which can improve the material structure of batteries.

 

Without fundamental technological advances for batteries electric cars will remain a niche product without any progress regarding commercialization. It is therefore even more pleasant to see
latest news from companies such as Aleees. Recently, the Taiwanese
manufacturer Advanced Lithium Electrochemistry Co., Ltd. (Aleees), discussed its innovative double-layer nano-carbon coating technology at the 220th Electrochemical Society (ECS) meeting held in Boston (U.S.). 

 

Aleees has created an innovative double-layer nano-carbon coating technology which allows olivine material to be coated with different carbon compounds with thicknesses less than 5nm so as to improve the structural integrity of the material and enhance the life cycle of batteries by 2.7 times! 

 

Besides developments from big blue chip companies such as IBM,Matsushita, Panasonic, Sanyo, Mitsubishi or NEC Corporation it is the smaller innovative enterprises like Altair Nanotech, Cymbet, ITN Energy Systems, Blue Spark Technologies (formerly Thin Battery Technologies) or PolyIC that enormously drive the commercialization progress of electric vehicles. Most important: New investments will create new jobs. 

 

Alongside the increasing news on batteries the graphene topic remains up-to-date and has priority once again like in our Jun-/Jul-11 edition (topics include e.g. worldwide patent filings, computer chips with graphene, graphene and the terahertz band).

Building Energy Storage Device on a Single Nanowire [24]

The world at large runs on lithium ion batteries. New research at Rice University shows that tiny worlds may soon do the same.

The Rice lab of Prof. Pulickel Ajayan has packed an entire lithium ion energy storage device into a single nanowire. The researchers believe their creation is as small as such devices can possibly get, and could be valuable as a rechargeable power source for new generations of nanoelectronics.

In their paper, researchers described testing two versions of their battery/supercapacitor hybrid. The first is a sandwich with nickel/tin anode, polyethylene oxide (PEO) electrolyte and polyaniline cathode layers; it was built as proof that lithium ions would move efficiently through the anode to the electrolyte and then to the supercapacitor-like cathode, which stores the ions in bulk and gives the device the ability to charge and discharge quickly.

FeTRAM - A New Type of Computer Memory [27]

 

Researchers at Purdue's Birck Nanotechnology Center (USA) are developing a new type of computer memory that could be faster than the existing commercial memory and use far less power than flash memory devices. The technology combines silicon nanowires with a "ferroelectric" polymer, a material that switches polarity when electric fields are applied, making possible a new type of ferroelectric transistor. 

 

The ferroelectric transistor's changing polarity is read as 0 or 1, an operation needed for digital circuits to store information in binary code consisting of sequences of ones and zeroes. The new technology is called FeTRAM, for ferroelectric transistor random access memory.

Rice Researchers Power Line-voltage Light Bulb with Nanotube Wire [28]
 
Cables made of carbon nanotubes are inching toward electrical conductivities seen in metal wires, and that may light up interest among a range of industries, according to Rice University researchers. 
 
A Rice lab made such a cable from double-walled carbon nanotubes and powered a fluorescent light bulb at standard line voltage - a true test of the novel material's ability to stake a claim in energy systems of the future. The cables developed in the study are spun from pristine nanotubes and can be tied together without losing their conductivity.

Electric Motor made from a Single Molecule [30]

 

Chemists at Tufts University's School of Arts and
Sciences (U.S.) have developed the world's first single molecule electric motor

 

The Tufts team reports an electric motor that measures a mere 1nm across, groundbreaking work considering that the current world record is a 200nm motor.

 

"There has been significant progress in the construction of molecular motors powered by light and by chemical reactions, but this is the first time that electrically-driven molecular motors have been demonstrated, despite a few theoretical proposals," says E. Charles H. Sykes, Ph.D., associate professor of chemistry at Tufts and senior author on the paper. "We have been able to show that you can provide electricity to a single molecule and get it to do something that is not just random."

Printed Photovoltaic Cells on Paper [34]


Researchers at Chemnitz University of Technology, Germany, have now presented solar panels that are printed on paper. The technology known as 3PV - Printed Paper Photovoltaics - uses conventional printing methods and standard substrates, like those used for magazines, posters or packaging.

Special inks with electrical properties form the necessary structures on paper, which ensure that electricity is generated when being exposed to light. Since the employed conventional printing methods, i.e. gravure, flexo and offset printing, are very cost-efficient, the printed solar panels shall generate much cheaper electricity in comparison to conventional solar cells.
