Lead prices rose, as European drivers to choose a new battery

London, Jan. 8, according to news, cold winter and the recession has forced more and more European motorists who choose to replace the new battery, which lead to weak prices a boost.

Share of global vehicle battery over 40% of lead demand, analysts said the increased use of batteries has helped boost the 60% decline in 2008, lead prices.

According to auto repair station said the surge in demand for batteries.

RAC British car repair company, said its data show that in January this year, go out the battery-related repair services increased by 5% over last year.

RAC manager John Clayton said: "We are now in red alert, everyone could work out maintenance of vehicles."

"Of course most of the battery-related."

Car batteries in the cold of winter use significantly increased.

Battery life of a vehicle in about five to eight years, the average content of 5-25 kg of lead batteries.

UK vehicle recovery and maintenance services company Green Flag, a rescue station operator Richard Colburn said: "We are really very busy at the moment, more than 400 every day this week for help."

"Most of them are caused by extreme cold weather, battery-related failures, the temperature in parts of -9 degrees. We are in December and January a lot of battery replacement."

Lead prices bounce

Lead the market in recent months has been the auto industry to suppress negative data.

This has lead prices from October 2007 reached a record high of USD 3,890 per tonne, plunged about 70%.

But since the New Year began, lead prices have surged 15%.

Barclays Capital analyst Gayle Berry said: "Over the past week or two weeks, China's car Zheyi in replacing the car battery before the holiday season."

"We see the lead prices by supporting ...... Unlike many other metals, lead prices we have seen gains are supported by improved fundamentals."

Kwik Fit auto parts retailers in Europe, a spokesman said, although the upward trend in car sales conclude too early, but the situation is improving.

"A key driver of battery sales are seasonal fluctuations. For example, the battery last week, a substantial increase in sales over last year due to cold."

AMD introduces DirectX 11 graphics chip ATI Radeon HD 5830 before

Video cards using the high-end GPU will be available in 5830 for around 230 euros. The chip works with a core clock of 800 MHz, the memory at 1000 MHz. The performance suffers significantly due to numerous architectural limitations.

Business blogs: Lenovo ibm Battery , dada ,justblogme , zoomshare , tumblr ,ameblo , sony vgp-bps9/s battery , etc.

AMD today officially introduced the ATI Radeon HD graphics 5830th With the GPU, the manufacturer completes its high-end portfolio with the single GPU models 5870 and 5850 downwards. While the two fastest solutions for 360 euros (Radeon HD 5870) and 250 (Radeon HD 5850) are available, will cost graphics cards with the Radeon HD 5830 about 230 euros.

The Radeon HD 5830 differs from the faster models by the number of computation, texture and raster operation units (ROP). Instead of 1600 stream processors, and available on the fastest graphics chip (Radeon HD 5870), uses the 5830 only 1120 units. The HD 5850 features 1440 stream processors.

However, due to the GPU clock of 800 MHz with 5830 only slightly below the top model with 850 MHz and higher than that of 5850 with 725 MHz. The faster the chip clock reached only by a voltage increase, which is the reason for a slightly higher power consumption at full load compared to the HD 5850th

The raster operation units are limited to 16 in 5830, while have the two fastest variants of the 5800er-line over twice that number. The architectural limitations affect the performance of graphics chips considerably. Thus, the texture fill rate is of 5830 with 44.8 GTexel / s compared to 5850 with 52.2 GTexel / s and 5870 with 68.0 GTexel / s significantly lower. The pixel processing power suffers from the circumcisions: while the top model one Pixelfüllrate GPixel of 27.2 / s and offers 5850 to 23.2 GPixel / s comes, must be content with only 12.8 of the 5830 GPixel / s. Thus equipped the 5830 5770th in this discipline is not even the power of 100 euros cheaper HD

Which are compared to the fastest models in the lower 5800er Series theoretical performance values of an adverse effect in practice. Thus, the Radeon 5830 in game tests achieved significantly lower performance than the little more expensive Radeon HD 5850th Even the Nvidia Geforce GTX 260 is the Radeon HD 5830 in some tests outperform. The available starting from 170 Euro model DX10 ATI Radeon HD 4890 offers the HD 5830 also in many cases, stand up.

In total, the ATI Radeon HD 5830 with a price target of 230 euros for ambitious players to little power. Radeon HD 5850 graphics cards cost only 20 euros more and offer much higher performance. provides for the standard user who place heavy emphasis on DirectX 11 graphics cards, but not as high demands on the performance, the 5770 and 5750 models are better. The latter are available from 110 Euro.

Nvidia can not currently come up with similar solutions. First DX11 models of AMD’s competitor will introduce in late March. The market launch is expected to recent rumors that move but up in May.

The ATI Radeon HD 5830 AMD completes its high-end portfolio with the single GPU models 5870 and 5850 downwards. Because of numerous architectural limitations made the chip, however, significantly less performance than the top models of the 5800er series.

Zhengrong Shi predicted solar cell prices will drop within a decade and a half

Energy richest man Zhengrong Shi on March 20 opened in Shanghai, “China International Industry Fair,” the said large number of Chinese companies flocking into the solar photovoltaic industry, the products so that the upstream polysilicon demand, price increases, but the result of homogeneous competition will be ten years later halved the price of silicon. At the same time, he believed that the real competitor is the solar thermal power generation and other traditional industries, rather than between the same industry escalating price war.

Ten years later half of the silicon prices will drop

Europe, a study recently reported that by mid-century solar power will account for 30% of the entire energy supply, while the end of this century that proportion will rise to 70%. Zhengrong Shi pointed out, solar industry is the future of energy development. Although the demand for solar energy grew by 37% within 5 years, but only a few years China’s solar companies have as many as 400 to 500. This pushed up upstream prices of polysilicon and other raw materials.

Over the past 3-5 years, polysilicon prices rose 165%, while in China, prices rose by as much as 200%. 2006 second and third quarters, China’s solar cell to achieve the highest price in history, that one watt of solar cells 4 to 5 dollars. In the fourth quarter, there were obvious signs of decline, a drop of 5% to 10%. “Next year, this figure will fall by 5% to 10%.” According to analysis of 2016 1 watt of solar cells for two U.S. dollars a price below the market will change significantly.

Dr. Shi believes that in order to make the prices of end products can be declining battery, technical innovation and equipment must be modified. The technical innovation is the use of thin film batteries, which is the original battery replaced with 300 micron 2 to 3 microns or even thinner battery, saving cost, but also applicable to a wider range of industries. If the thin film battery with the existing mature cells of the conversion rate of polysilicon line, or 15%, and the future market will be dominated by thin film batteries.

The battery life is the main discipline of the Asus UL30A, because the computer runs and runs without electricity. Tap only after almost ten hours shows the battery fatigue. This represents a flight from Frankfurt to San Francisco. Two films of the “Lord of the Rings” trilogy can be enjoyed thanks to six hours running time multimedia service road on the drive to Italy. The eight-cell battery with 5600 milliamps does a thorough job.

The touchpad Asus embeds directly into the palm rest, the input surface is different from the housing surface only through the dimpled surface. For Touchpadtasten Asus follows the trend towards the rocker. Therefore, only offer Tastenenden a successful pressure point - a classic touchpad with two separate keys can use more pleasant. The keyboard is characterized by large distances and a pleasant print key point. Asus is based at the keyboard layout on the desktop standard.

Interfaces, and a second operating system: apple a1008 , apple a1012 , apple A1021 , apple a1022 , apple A1036 , etc.

The only difference between the terminals and the interfaces of the UL30A EeePC 1005PE is in HDMI output. As with 1005PE are three USB ports and one VGA and LAN port on the sides of the sub-notebooks. Wireless Internet users can go to the WLAN. Bluetooth does not offer the test pattern.

However, the subnotebook is available in several slightly different versions for sale, including a configuration with a Bluetooth module. While it imposes itself formally to the UL30A get most of the move to waive the user has when connecting external hard drives, but at a eSata port. A card reader and a webcam round out the equipment list.

How many EeePC models also has the Asus UL30A on the alternative operating system “Express Gate”. Just six seconds after pressing the power switch of the second computer so ready to use. Express Gate is ideal for surfing the Internet, phone or music listening. As a primary operating system Windows 7 uses the Home Premium 64-bit edition available. On Windows, the user can also switch to the second power switch between different modes of operation of the computer.

Conclusions: Good long-distance runner

For 600 euros, there are currently no subnotebook with such a long battery life. Take for the comparatively low price, however, compromising the user must monitor and touchpad in purchasing. Also, the manufacturer saves on the interface - eSATA and Bluetooth are many devices in this price range as standard. The rest of the hardware equipment but if this is fully in order.

Whether Intel, AMD to make every effort to reduce the power consumption of the hardware platform, and now laptops are unable to obtain all-weather 8-hour battery life, the key crux of the problem lies in lithium battery technology limitations, it is difficult to provide a high enough capacity. Two years ago, fuel cells, once is quite strong, but now attributed to silent, of course, fuel cells can provide longer battery life, but it's inconvenient to use, and the high cost of sales in consumables way, it is difficult to obtain broad market recognition, development of high-capacity lithium battery technology has become the industry consensus.

Stanford University announced today that one of their team in the field of lithium batteries was a revolutionary breakthrough, the research team has successfully developed a silicon nanowire technology, you can increase the capacity of lithium batteries 10 times, if you use this new type of battery , notebook computer battery life performance increase from the current two hours to 20 hours or more! Developers believe that this technology is not similar to the type lithium polymer technology improvements, but rather bring about revolutionary progress!

We know that the capacity of lithium-ion battery(Dell Battery , dell C1295 , dell D5318 ,dell GD761 , dell GK479 , dell KD186 , dell KD476 ) anode from the lithium ion can attach the number of decisions, attached greater the number of lithium-ion battery capacity of the greater! In the charging process, with the positively charged anode of lithium-ion will be absorbed by silicon material, making expansion of silicon material; in the work of discharge, lithium-ion will be released from the silicon to make silicon material shrinkage occurs - this expansion and contraction will lead to repeated silicon to become powder, resulting in diminishing the capacity of the battery. Stanford research results to solve this problem, they used nano-technology is made of silicon nanowires as the anode, and in the absorption of lithium ions can be expanded four times, while in the discharge process would not lead to powdering, or broken, which means not only to ensure that the battery capacity increase 10 times, and can significantly extend battery life.

The research team did not say when it will push the commercialization of this technology, according to Stanford's entrepreneurial culture, the research team can use the research results of the establishment of enterprises, by way of technology licensing operation, if the silicon nanowire lithium batteries can be really involved in commercialization, it will completely solve the shortage of digital devices, battery life, short life problem - then your laptop could easily rely on batteries to work 20 hours or more, so that the battery mode, the hardware performance do not have to drop too low; UMPC, smart phone, etc. handheld devices can also be obtained rapidly.

In the third report, Devanathan, Venkatnathan, and Dupuis computed the dynamical properties of water molecules and hydronium ions in Nafion and related them to the structural changes reported previously. They confirmed other researchers’ finding that the behavior of water molecules within nanoscale pores and channels of PEMs, especially at low hydration levels, is remarkably different from that of molecules in bulk water.

At low hydration, fewer than 20% of the water molecules are free (bulklike). With increasing hydration, the diffusion coefficients of hydronium ions and water molecules increase, and the mean residence time of water molecules around sulfonate groups decreases. These results provide a molecular-level explanation for the proton and water dynamics observed in neutron scattering experiments.

Because the structure and dynamics of the membrane under different levels of hydration cannot be directly observed in experiments, there is no universally accepted model of the structure of Nafion. This research makes a significant step toward that goal and toward the development of the next generation of PEMs.

Characteristics of the ideal PEM include high proton conductivity at low hydration levels; thermal, mechanical, and chemical stability; durability under prolonged operation; and low cost. None of the existing membranes meet all these requirements, and developing new membranes requires a molecular-level understanding of membrane chemistry and nanostructure. Molecular dynamics simulations like these, together with experiments, are laying the foundation for future breakthroughs in fuel cells.

A fundamental understanding of the relationship between membrane nanostructure and the dynamics of water molecules is needed for the development of efficient, reliable, and cost-effective membranes to advance PEM fuel cell technology. The structure and dynamics of the polymer membranes under different levels of hydration cannot be directly observed in experiments, but they can be modeled in molecular dynamics simulations, as shown in a series of three papers published in the Journal of Physical Chemistry B by Ram Devanathan, Arun Venkatnathan, and Michel Dupuis of Pacific Northwest National Laboratory (PNNL).
