Super laptop Battery

Super laptop Battery Ever wish you could charge your cellphone or laptop in a few seconds rather than hours? As this ScienCentral News video explains, researchers at the Massachusetts Institute of Technology are developing a battery that could do just that, and also might never need to be replaced.

The Past is Future

As our portable devices get more high-tech, the laptop batteries that power them can seem to lag behind. But Joel Schindall and his team at M.I.T. plan to make long charge times and expensive replacements a thing of the past–by improving on technology from the past.

They turned to the capacitor, which was invented nearly 300 years ago. Schindall explains, “We made the connection that perhaps we could take an old product, a capacitor, and use a new technology, nanotechnology, to make that old product in a new way.”

Rechargable and disposable batteries use a chemical reaction to produce energy. “That’s an effective way to store a large amount of energy,” he says, “but the problem is that after many charges and discharges … the battery loses capacity to the point where the user has to discard it.sony vgp-bps2c,vgp-bps2a“

But capacitors contain energy as an electric field of charged particles created by two metal electrodes. Capacitors charge faster and last longer than normal batteries. The problem is that storage capacity is proportional to the surface area of the battery’s electrodes, so even today’s most powerful capacitors hold 25 times less energy than similarly sized standard chemical batteries.

The researchers solved this by covering the electrodes with millions of tiny filaments called nanotubes. Each nanotube is 30,000 times thinner than a human hair. Similar to how a thick, fuzzy bath towel soaks up more water than a thin, flat bed sheet, the nanotube filaments increase the surface area of the electrodes and allow the capacitor to store more energy. Schindall says this combines the strength of today’s batteries with the longevity and speed of capacitors.

“It could be recharged many, many times perhaps hundreds of thousands of times,sony vgp-bps5a ,vgp-bps2c and … it could be recharged very quickly, just in a matter of seconds rather than a matter of hours,” he says.

This technology has broad practical possibilities, affecting any device that requires a battery. Schindall says, “Small devices such as hearing aids that could be more quickly recharged where the batteries wouldn’t wear out; up to larger devices such as automobiles where you could regeneratively re-use the energy of motion and therefore improve the energy efficiency and fuel economy.”

Schindall thinks hybrid cars would be a particularly popular application for these batteries, vgp-bpl2 ,vgp-bps2,especially because current hybrid batteries are expensive to replace.

Schindall also sees the ecological benefit to these reinvented capacitors. According to the Environmental Protection Agency, more than 3 billion industrial and household batteries were sold in the United States in 1998. When these batteries are disposed, toxic chemicals like cadmium can seep into the ground.

“It’s better for the environment, because it allows the user to not worry about replacing his battery,” he says. “It can be discharged and charged hundreds of thousands of times, essentially lasting longer than the life of the equipment with which it is associated.”

Schindall and his team aren’t the only ones looking back to capacitors as the future of batteries; a research group in England recently announced advances of their own.Sony vgp-bps2c, But Schindall’s groups expects their prototype to be finished in the next few months, and they hope to see them on the market in less than five years.

Schindall’s research was featured in the May 2006 edition of Discover Magazine and presented at the 15th International Seminar on Double Layer Capacitors and Hybrid Energy Storage Devices in Deerfield Beach, Florida on December 2005. His research is funded by the Ford-MIT Consortium.

Most notebook batteries begin to degrade after three to six months.

And runtime? Lampe-Onnerud said she gets four hours out of the conventionally sized Sonata plugged into her notebook on a regular basis in ordinary conditions. The power meters on most notebooks say they get four hours,hp pavlion dv6000 battery, but in reality the runtime is shorter than that.

There is a catch, however. The Sonata will sell at a premium.  Notebook makers always try to minimize component costs. Manufacturers also tend to be skittish when it comes to trying out products from start-ups.

No More Exploding Laptop Batteries?

Aww darn, no more cool explosions from exploding laptop batteries!  STOBA, a new material technology will steal the joy of seeing your laptop explode from faulty batteries. Boy, it seemed like a week didn’t pass without Apple, Toshiba laptop battery, Sony, Dell laptop battery, Sanyo, Lenovo, or some other laptop manufacturer issuing a battery recall due to exploding batteries. Well, apparently STOBA will make consumer electronics safer.

Taiwan’s Industrial Technology Research Institute (ITRI) has developed STOBA, a material technology that prevents lithium-ion batteries from overheating, catching fire or exploding.

Check out a video of how the technology works, including a demonstration on why lithium-ion batteries explode. There is an animated explosion in the demo, so enjoy.

ITRI’s STOBA material technology for Lithium-ion batteries has received a 2009 R&D 100 Award.

Innovative Technology is First to Ensure the Safety of Lithium-ion Batteries
Used in Many Consumer Electronics and Electric Vehicles

HSINCHU, Taiwan, Nov. 12, 2009 – ITRI (Industrial Technology Research Institute), Taiwan’s largest and one of the world’s leading high-tech research and development institutions, will accept a “2009 R&D 100 Award in Energy Devices” today, in Orlando, Fla., for developing STOBA (self-terminated oligomers with hyper-branched architecture), the first technology to enhance the safety of lithium-ion (Li-ion) batteries.

“It is a great honor to be recognized by a publication as prestigious and influential as R&D Magazine,” said Dr. Alex Peng, senior research scientist and deputy general director at ITRI’s Material and Chemical Research Laboratories (MCL). “During the past five years, the STOBA team worked diligently to develop this technology. They have truly earned this achievement.” 

Li-ion batteries, the power source for many consumer electronic devices, including cell phones, laptops, MP3 players, cameras, and hybrid and electric cars, are susceptible to overheating, which can cause fires and explosions. In the past, safety standards for Li-ion batteries could not be raised because there was no solution available.

To meet the growing demand for high-safety lithium batteries, ITRI successfully developed STOBA, which has fundamentally resolved the safety issue. By integrating a nano-grade high-molecular polymer, which forms a protective film, into the Li-ion battery, a locking effect is generated when the battery encounters excessive heat, external impact or piercing and interrupts the electrical and chemical action, preventing explosions. In 2008 and 2009, STOBA passed the mandatory shorting and piercing experiments conducted by battery manufacturers in Japan and Taiwan. These intensive nail penetration and impact tests confirmed STOBA’s effectiveness in preventing internal shorting and overheating in Li-ion batteries.

For the past 47 years, The R&D 100 Awards have annually identified and recognized the 100 most significant and revolutionary technologies newly introduced to the market. Past winning technologies include the printer (1986) and HDTV (1998). An R&D 100 Award serves as a mark of excellence to industry, government and academia and confirms the technology is one of the top innovations of the year. This year’s winners will be honored at a ceremony this evening in Orlando, Fla.

Now charge mobile, laptop while you walk

Believe it or not, you may be able to charge your mobile, laptop and iPod by a few minutes of walk in near future. Scientists at Georgia Tech university have claimed to have developed the first device to tap the power of motion and produce practical amounts of electricity from piezoelectronics.

The team group said piezoelectrics can generate voltages up to 1.26 volts, and can produce even higher voltages, the Discovery Channel reported.

“This is a key step to designing technology that will be useful in the near future,” said co-author Z L Wang. “Every move you make, every step you take, you can generate electricity. The power output could quickly jump high enough to power iPods and cell phones,” Wang said.

By cramming 20,000 nanowires into three square centimetres, the scientists have created the world’s first device powered solely by piezoelectric materials.

A piezoelectric material is something that, when pushed or pulled, generates a mild electrical charge.

“Within three to five years piezoeleectric nanowires, woven into a cotton shirt or housed in a shoe heel, could charge a cell phone or laptop battery after even a short walk,” they said.

The group used plentiful and easy-to-manipulate zinc oxide nanowires to create their nanogenerator. Twenty thousand nanowires, placed side by side and end to end, covers three square centimetres, with two thin electrodes hanging off either end.

This unique arrangement maximises the electricity the piezoelectric nanowires can create. The wires work with each other, amplifying the electrical charge to record levels as the single layer is pushed back and forth with only the most slight and gentle of nudges.

“Pushing the arranged nanowires harder or faster would bump the power output up to 30 times without damaging the device. If more powerful, and more expensive, gallium nitride replaced the cheap zinc oxide nanowires the power output could increase another 10 times,” the team added.

That’s more than enough energy to power most consumer devices, if the piezoelectric material were in motion constantly. Other tiny piezoelectric-powered devices could sense fires and gather weather data in areas outside the reach of traditional power grids.

To power such small sensors Wang will create tiny batteries or supercapacitors to store the electricity generated by his advanced piezoelectric nanowires.
