And paper battery similar, researchers using the “carbon nanotube ink” disseminated clothing fibers, it has the ability to grasp the charge. When the clothes to retain sufficient charge, it can be treated the jacket to charge for the laptop, with trousers for

The same principle and paper battery

This fact is an extension of the concept paper battery. December 7 last year, Stanford University scientists in a report set, they have successfully coated with silver nano-materials, carbon paper into the “paper battery” may become a new light and efficient storage method. Help coating attached to the same characteristics of paper attached to it and the silver in the single-walled carbon nanotubes nanowires film. Preliminary study found that use of nanowires made of silicon cells, the efficiency is now used to power laptops and other devices lithium-ion batteries 10 times.

“This battery for hybrid electronic devices, or providing energy. Use of such batteries, electronic devices will become lighter, last longer, and may one day produce paper electronic products. Battery weight and life of the power cars and trucks in the commercial development of a major obstacle encountered. “Yi Cui said.

In this way through the fiber storage, in addition to portable electronic devices and wearable electronic devices you can use it outside, the researchers said some of the super capacitor paper can also be applied to all the energy needs of the instantaneous power equipment on. University of California, Berkeley, chemistry professor Yang Peidong expects the technology will soon be commercialized.

Solve high cost is a priority

But for the future of this new type of battery, in particular, will replace the current battery, there are different views on the industry. Harbin Institute of Technology School of Applied Chemistry Department Professor Sun Kening that the new paper battery batteries as a new concept, the use of outlook is definitely yes. However, the paper published the battery from the current methods of production point of view, the production of such paper batteries need high cost of production of carbon nanotubes, is not suitable for mass production, so its usefulness is limited. Due process and other reasons, it is not a substitute for extensive use of other types of batteries, and can not market share in a short time.

But be sure, the new batteries for laptop computers, mobile phones,

Digital

Camera and even

Car

Is an ideal drive. For example, because plasticity, such batteries can even be made into the shape of the door, with uncomparable advantages over other batteries.

Researchers most urgent task is how to reduce the cost of such batteries.

Batteries Going Green

For years, battery manufacturers have been developing ways to make their products more environmentally friendly.

Companies look for alternatives to the harmful substances used today. However, that strategy will take decades to commercialize; producing batteries that are stronger and more efficient seems the best option.

Presently, researchers are exploring “bio-batteries”, using substances made from living organisms to power objects.

In 2007, Sony developed a “bio battery” that generates electricity from sugar. This discovery uses carbohydrates and enzymes to generate power and has a maximum output of 50 milliwatts,giving it the capability to power a walkman. This has set path in turning to abundant living organisms to reduce toxic waste produced by batteries. (Sugar fuelled battery..,2007)

A recent development by a research team in Aarhus University in Denmark creates a bacteria colony that reacts with mud and seawater to generate electricity. The bacteria colony works by having contact on top with oxygen while the bottom contacts the organic material. Because both layers are somehow connected in the process, the bottom layer that produces electrons are transported to the top layers therefore reacting with oxygen. Scientists are trying to harvest the nanowire network that these bacteria creates to potentially developing a living biogeobattery (Anupanm, 2010).

Meanwhile, scientists at the University of Leicester are looking for ways to replace harmful, carcinogenic, toxic acids and electrolytes currently and widely used in many commercial metal finishing and energy storage processes (University of Leicester, 2010). So far they have developed ionic liquid solvents that are non-toxic as an alternative to dangerous solutions. Karl Ryder, a senior lecturer at the University who oversees the project explains, “One of our aims is to improve the working environment for people within the manufacturing industry by replacing unpleasant acids or caustic processes with ionic liquids. The user experience is very similar for both and no additional equipment or training is required, but the user benefits from a more pleasant and safer working environment.” (University of Leicester, 2010). The team of researchers received a €1 million funding distributed between several major projects.

One project called POLYZION was to develop an eco-friendly and affordable rechargeable battery for electric vehicles. It is designed to be sustainable, having light-weight characteristics as opposed to existing batteries that use heavy, expensive materials that can be harmful to the environment (University of Leicester, 2010).

Additionally, MIT researches are developing ways to manufacture liquid metal batteries made using earth-abundant elements. A big issue scientists faced in an attempt to develop eco-friendly batteries is the high cost of the material. MIT attempts to tackle this problem by using substances that are plentiful. As a result, the research team developed a small battery made from antimony and magnesium in between an electrolyte. As for now, the battery is not beneficial to small devices, but researchers continue to develop the product to a larger scale (Anupam, 2010 March 19).

Moreover, leading battery producers such as Fuji created the EnviroMAX batteries last year that do not contain ingredients harmful to the environment such as cadmium and mercury. They are packaged with recycled paper and PET plastic which makes the products degradable where they can be disposed normally. This decreases the costs incurred from recycling batteries (Hanlon, 2009).

Hitachi Vehicle Energy Ltd. Created a new Lithium-ion battery designed for automobiles. This new product has more capacity up to 25 Ah that is about 5 times more than its predecessors. It produces energy of up to 120 Wh/kg and power density of 2,400 W/kg. It further provides heat-resistant features preventing internal short circuits and increasing safety (Madan, 2010).

The market today focuses on the emerging green market. Companies spend millions on the research and innovation sector to develop methods of increasing efficiency to reduce waste, or finding abundant alternatives to current methods. Many have succeeded, but may take time until the developments are released to the masses. Nevertheless, the decision remains in the hands of consumers to persistently push towards the eco-friendly movement.

Bio-Engineered Batteries?

It seems Angela Belcher’s lab, Biomolecular Materials Group at MIT, has come up with a new microminiature battery, developed from genetically altered viruses, that could change technology as we know it!

The minute size of this battery has incredible application implications for the powering of electronics, electric cars, and the military.

“We can make them in larger diameters,” Belcher said, “but they are all 880 nanometers in length,” which matches the length of the individual virus particles. And, “once we’ve altered the genes of the virus to grow the electrode material, we can easily clone millions of identical copies of the virus to use in assembling our batteries. For the metal oxide we chose cobalt oxide because it has very good specific capacity, which will produce batteries with high energy density.”

More bang for the buck is what this all measures up to. Just to give you an idea of themicroscopicity of this itty bitty battery, a nanometer is one billionth of a meter (500 times smaller than the tip of your pen). And for you engineers, the anode and electrolyte elements for this battery are a done deal. The cathode has given them some difficulty but there are a few working prototypes in the lab, as we speak.

“The nanoscale materials we’ve made supply two to three times the electrical energy for their mass or volume, compared to previous materials,” the team reported.

These futuristic batteries are so tweaky that they could be interwoven into fabric for military applications (the ultimate in warfighting battle armor). “We definitely don’t have full batteries on those [fiber architectures]. We’ve only worked on single electrodes so far, but the idea is to try to make these fiber batteries that could be integrated into textiles and woven into lots of different shapes,” Belcher says, explaining that much of this is still in the works, but that it is conceivably possible, in the very near future, that people’s clothing, cars, aircraft skins, etc. may be interwoven with finely spun power filaments for every application imaginable.

The size and weight of standard batteries powerful enough to propel electric cars has always been an engineering constraint in design.

The positively-charged anode is created by genetically altering the virus so that it draws to itself the materials it needs to become “the positive terminal” of the battery. “Once you do the genetic engineering with the viruses themselves, you pour in the solution and they grow the right combination of these materials on them,” Belcher says. Basically, the microbes collect exotic materials, primarily cobalt oxide and gold. And because these viruses are negatively charged, they can be sandwiched in between oppositely charged polymers to form thin, flexible sheets or spun from liquid crystal like a spiderweb to series or parallel strings of tiny power producing networks.

“What we’re working on is not thinking about a particular device application, but trying to improve the quality of the anode and cathode materials—using biology just to make a higher quality material for energy density,” Belcher says. “We haven’t ruled out cars. That’s a lot of amplification. But right now the thing is trying to make the best material possible, and if we get a really great material, then we have to think about how do you scale it.”

This research was funded by the Army Research Office Institute of Collaborative Biotechnologies, the Institute of Soldier Nanotechnologies and the David and Lucille Packard Foundation.

Nanocomposite Said To Boost Lithium Batteries By 5X

Nanocomposites aim to boost the capacity of lithium ion batteries by five-times by hanging nanometer-sized silicon particles on trees of carbon black that self-assemble into porous micron-sized spheres, which increase an electrode’s surface area with interconnected internal channels.

High-performance lithium ion batteries today use anodes made from carbon (graphite). Silicon has been proposed as a substitute for graphite since it offers a theoretical improvement of 10-times in capacity over graphite, but so far prototypes have proven too unstable for creating lithium batteries with a long lifetime, according to professor Gleb Yushin at the Georgia Institute of Technology.

The problem, according to Yushin, is that silicon particles crack when they are formed at the same granularity of graphite particles—about 15 to 20 microns. The new nanocomposite material solves that problem by hanging 30 nanometer sized silicon particles on trees of carbon black which then self-assemble into porous spheres about 10-to-30 microns in diameter. The resulting electrode remains stable due to the durable carbon-superstructure that prevents cracking, but benefits from the increased surface area afforded by the smaller silicon nanoparticles.

Common chemical vapor deposition processes allow the new hybrid silicon-carbon electrodes to be mass produced economically, according to Yushin. He also claimes that because the tiny silicon nanoparticles are permanently attached to the micron-sized carbon black trees, they avoid the health hazards of processes that require handling of nanoscale particles.

So far Georgia Tech has fabricated experimental anode electrodes, which it is testing for use in standard manufacturing processes for lithium batteries. Their prototype has survived over one hundred recharge cycles without any degradation, leading the researchers to predict they will last for thousands of recharges.

Besides Yushin, other Georgia Tech researchers involved in the project include Alexandre Magasinki, Patrick Dixon, Benjamin Hertzberg and Alexander Alexeev, along with Alexander Kvit from the University of Wisconsin-Madison, Igor Luzinov from Clemson University, and Jorge Ayala from Superior Graphite (Chicago).

Funding was provided by a Small Business Innovation Research (SBIR) grant from the National Aeronautics and Space Administration (NASA) to Superior Graphite and Streamline Nanotechnologies, Inc.
