Fuel cells and raw materials

Predicted in 2007 gasoline prices Dell Latitude D610 Battery will increase 27%. Supply disruption in Nigeria, Iran’s nuclear problem may be caused by interruption of oil exports, as well as declines in U.S. gasoline stocks since April 2006 prices increased significantly. Brent oil price from 66 U.S. dollars / barrel soared to 73 U.S. dollars / barrel. Oil prices in 2007 is expected to be raised to 63.7 U.S. dollars / barrel. According to a variety of ways to predict, in 2010 China’s natural gas consumption will reach 1000 × 108 Lifang Mi / a about.

China’s methanol consumption in recent years has maintained rapid growth momentum, 1998 and-2004 average annual growth rate of 15% in 2004 to 5.73 million tons, while domestic methanol production over the same period was only 4.406 million tons, showing the situation of short supply. But the future of new methanol production capacity can quickly enlarge, thus reversing the supply and demand. Is expected in 2010 China’s methanol production capacity reached 15 million tons in 2015 will reach 24.1 million tons. The demand side, formaldehyde, methanol consumption is still the main driving force is expected in 2010 will consume four million tons of methanol, in addition to acetic acid production capacity in 2010 to reach 3 million tons required to consume 1.9 million tons of methanol, combined with MTBE, and other downstream products the needs of development status of China’s methanol demand in 2010 is expected to reach 12.3 million tons in 2015 to 24.5 million tons (The above data comes from coal Network). To preliminary statistics, China’s current project under construction or official of the methanol project in less than 50, the methanol project under construction production capacity more than 4 million t / a, while the proposed methanol plant and planning capacity of more than 20 million t / a. If the projects Dell Latitude D620 Battery are all carried out in accordance with the planning, then (of course, a lot of projects in the planning stage only), the next two to three years may be focused on the situation of heavy volume, which will have a major methanol’s future price of negative effects. In addition, most new projects are concentrated in the central and western areas, which will lead to a regional excess of methanol supply problems.

“Made in China” to change the market structure

Domestic battery sweep pattern of the Chinese market is clearly inseparable from its efforts over the years. In order to rewrite the past, Japanese-brand batteries rampant in the Chinese market situation, South-fu, Double Deer, White Elephant and so provoked the burden of domestic battery brands to create a scientific and technological innovation “Made in China” journey. Which ranked top in the domestic market of South-fu batteries, but also by virtue of a powerful “Plant science research” independent innovation mechanism, in the process, technology, product innovation and other aspects of comprehensive research and development, become the largest alkaline battery brands.

Philosophy of environmental protection from a sense of responsibility with Dell Latitude D820 Battery

The overall rise of China’s battery business benefited from strong corporate social responsibility. Domestic battery is no longer based on the current corporate cost of pollution to the environment to develop business, but through the “green revolution” to win customers and markets. Back in the early 90s of last century, the Chinese battery manufacturer with a sense of responsibility and mission to begin the process of environmental protection battery production. Like Nanfu, through independent research and technological innovation, the success of transformation out of the world’s most advanced production lines, and in 2000 the first full realization of alkaline manganese batteries mercury-free products. Fu, etc. in the South under the leadership of a number of enterprises, the domestic many large companies also have the battery began to restructure production of environmentally friendly energy saving alkaline Dell Inspiron 6000 Battery.

Can be said that the success of China’s battery production companies, not dependent on the cheap “Made in China” and the international brand price competition, but through constant innovation in technology and market, through the international standards of quality and Dell Laptop battery marketing have won consumers and market.

Silica nanoparticles and solar cells

February 3rd, 2010

Silica nanoparticles and solar cells

Scientists digital camera battery have been working to find better materials and methods to create high-performance solar cells. U.S. scientists, a new study found that in silicon solar cells formed on the surface layer of silicon nanoparticle films can enhance the ability of its energy conversion and reduce the battery’s own heat and prolong life. Relevant papers will be published in “Applied Physics Express” (Applied Physics Letters) on.

The study was conducted by physicists at the University of Illinois Munir Nayfeh leadership, mainly targeted at the ultra-violet absorption and transformation. In terms of traditional solar cells, ultraviolet light leaking out of line either directly or by absorption of silicon devices, but it is converted into heat instead of electricity, which may affect the service life. In 2004, published in the “Photonics Technology Letters” (Photonics Technology Letters) in a study, Nayfeh confirmed that the UV lines with the appropriate nano-scale particles kodak klic-5001 effectively combined to produce electricity.

In order to achieve practical results, Nayfeh and his colleagues conducted a new study. They first use its own developed a proprietary technology to larger silicon switch is made of discrete nano-scale particles, they will be issued in different colors of fluorescence. Then, the researchers of these particles dispersed in isopropyl alcohol and wipe the surface of the solar cell. When the alcohol evaporates, the surface of the battery will eventually form a tight layer of nano-granular films.

The researchers found that if the solar cells covering the surface is the thickness of 1 nm blue fluorescent nano-particles thin-film, the entire cell will be able to transform more than 60% of the UV lines, but the visible light, the conversion rate of increase less than 3%. However, if the battery is the thickness of the surface covered by 285 nm red fluorescent particle film, then the ultraviolet ray kodak klic-7001 can increase the conversion rate of 67%, while the enhancement of visible light can reach 10%.

Nayfeh that the performance of solar cells such improvements should be more attributed to the improvement of the battery voltage rather than current. He said, “Our study conclusions indicate that charge transfer within the thin film and nano-particle interface, the importance of the amendment.”

Nayfeh said that the new coating process can easily incorporated into the current solar cell manufacturing process, while the costs are not an additional increase.

Nokia intends to be completed end of this year recovery plan for bad batteries

Nokia Corporation (Nokia Corp.) Spokesman Marianne Holmlund said the kodak klic-7004 company plans to complete its year-end 2007, the battery restoration program. The company currently too much heat is being replaced with 4,600 million cell phone batteries.

According to “Nihon Keizai Shimbun” (Nikkei) reported, Holmlund said, Nokia is working with Matsushita Electric Industrial Co., Ltd. (Matsushita Electric Industrial Co.) Cooperation to ensure that problems with lithium batteries can be repaired as soon as possible. Those batteries from Matsushita Battery Co., Ltd. (Matsushita Battery Industrial Co.) Manufacturing.

The Finnish mobile phone giant has released the battery product advice, because of the problems these batteries overheating while charging the battery itself, leading to deformation. Nokia insists that this is not a serious injury due to battery overheating carried back to the response, but consumers demand the product should be replaced.

Holmlund said that Nokia batteries to fix all problem is very difficult, like the call back to the car and computer parts products, fixed rates are usually 30% or less.

If the battery is low repair rate, Nokia is likely to consider continuing the Dell Latitude D510 Battery in 2007 after the rehabilitation program.

Holmlund did not indicate the cost of replacement batteries. Once the battery is expected to identify the cause of the malfunction, Nokia and Panasonic will be sharing costs.
