Dell Laptop Battery Use and Maintenance

Some companies have tinkered with the internal chemistry of the batteries. Notebooks contain lithium cobalt batteries. Altair Nanotechnologies and EnerDel have devised lithium titanate batteries, while others have come up with lithium potassium batteries. hp laptop battery The change in chemistry lowers the risk of explosions, dell precision m65 battery but also lowers the energy density. Lower energy density directly leads to lower mileage or runtime on laptops. Others are looking at getting rid of lithium altogether and switching to a rechargeable zinc battery.

“Some factories still use very, very rudimental quality measures,” she said.

At the same time, the Sonata will outperform conventional batteries, http://www.toplaptopbatteries.com/acer/as07b42.htm the company said. It will recharge from depleted to 80 percent capacity in about 30 minutes. dell inspiron 1520 battery The Sonata also will provide like-new performance for three years, according to the company. 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.

The Industrial Technology Research Institute (ITRI) is a nonprofit R&D organization engaging in applied research and technical services. Founded in 1973, ITRI has played a vital role in transforming Taiwan’s economy from a labor-intensive industry to a high-tech industry. Numerous well-known high-tech companies in Taiwan, such as leaders in the semiconductor industry TSMC and UMC, can trace their origins to ITRI.

Paper Battery Said To Outperform Lithium Ion

A paper battery based on carbon nanotubes and silver nanowires could store an electric charge in a mobile device. Researchers also claim the new battery is disposable and that its shape could conform to the shape of different devices.

A Stanford University researcher said his team has demonstrated conductive coatings for battery components ranging from supercapacitors to inexpensive electrodes. The process could be commercially available in several years, according to Yi Cui, a Stanford assistant professor of materials science and engineering.

“Paper can now be used as a substrate to make functional conductive electrodes,” the Stanford researcher said.

The conductive paper was prepared by coating it with a special nano-ink solution containing carbon nanotubes and silver nanowires, which assemble into a thin film of one-dimensional structures that adhere to the fibrous paper surface. The coated sheet of paper became a highly conductive storage device, which the researchers charged, then connected to power light-emitting diodes.

Batteries can store a charge longer than capacitors but cannot supply as much current per unit of time. Stanford’s conductive paper could be used to build either type, but the researchers claim that its high conductivity and high surface-to-volume ratio could enable supercapacitors for electric cars, which depend on quick jolts of electricity during acceleration.

The researchers also predict that paper storage devices could be used in massive arrays to store excess energy from power grids at night, then redistribute it during the day.

In tests, the Standford researchers were able to charge and discharge the paper battery up to 40,000 times, a 10-fold increase over conventional lithium-ion batteries.
