Officials in recent days

Sony laptop battery, the United States and Japan cooperative research in clean hydrogen energy technology to reach a consensus. January 8, in Japan, visiting U.S. Energy Secretary Spencer Abraham and the Japanese Ministry of Economy, Trade and Industry signed a cooperative research on hydrogen and fuel cell technology of paper battery technology. Abraham said that international cooperation is the key to achieve both goals. Hydrogen battery is considered a clean and highly efficient battery. People to promote the use of hydrogen energy, said people will no longer be dependent on oil, they asked for a reduction in pollution.


Japan and the United States officials and technical experts will be in fuel cells and technology policy, as well as hydrogen production, storage and transport technology cooperation.VGP-BPL2, Japan and the United States is the “hydrogen economy International Cooperation Organization” members. The organization set up in November last year to promote hydrogen production, storage, transport and end-user and technical exchanges, to complete the common use of hydrogen battery code and meet the relevant standard.

Internet survey, said the first quarter notebook sales accounted for nearly 20%


Market research firm DisplaySearch,PCGA-BP2T, said Wednesday first quarter of this year the Internet the world’s notebook sales accounted for nearly one-fifth.


DisplaySearch said the first quarter of Internet sales for the nearly 600 million units to 30.5% Acer trick won market share. Internet sales of the Acer is its closest competitor - ASUS twice.


DisplaySearch said that the Internet in Latin America, North America, Asia (excluding Japan and China), as well as Europe, the Middle East and Africa (hereinafter referred to as “EMEA”) sales of the most popular areas. EMEA accounted for the sales of Internet access for about 45%, 26% in North America. Telecommunications companies to provide subsidies to boost the sales of the European Internet.


EMEA notebook market share of 38% market share in North America less than 30%. PCGA-BP2V,HP Notebook sales more than 7.3 million units, a market share of 24.1%. Acer to 18.8 percent market share over Dell to become the second largest notebook manufacturers, Toshiba, Lenovo are third and fourth respectively. DisplaySearch said that, in addition to Acer, the Internet present in the other four major notebook PC manufacturers in the proportion of sales are less than 10%.


John Jacobs, DisplaySearch analyst (John Jacobs) said in a statement that, at present, in the PC market of the Internet plays an important role. If it is not the Internet of the first quarter this year, notebook sales will decline 19 percent, rather than 3%. Market research companies Gartner and IDC also believes that online sales of the pull of the PC.

Acer notebook sales will advance beyond the Hewlett-Packard

Acer chairman JT Wang has said that the Internet and low-cost, driven by notebook computers, Acer will be ahead of schedule “beyond 2011 Hewlett-Packard became the first major notebook computer manufacturers,” the goal.


According to foreign media reported that Wang said, PCGA-BP4V,“our competitors in the Internet not take the initiative in this market, and now, we are a market leader in notebook rivals 6-9 months, so we are expected to become the first major notebook computer manufacturers will be will advance. “Wang did not disclose his Acer laptop is expected to more than HP time sales.


Acer last year’s sales of 500 million online this is the Internet’s largest manufacturers. Acer announced last month Timeline notebook computers, to provide 8-hour laptop battery life, hoping to narrow the gap with Hewlett-Packard.


Wang said that Acer expects sales this year from 12 million to 15 million Taiwan Internet of the Aspire One,PCGA-BP71, 7-1000000 Taiwan notebook Timeline. Acer notebook sales this year will be 2 million units last year, based on the growth of 35%.


Market research firm Gartner shows that the fourth quarter of last year, Hewlett-Packard notebook computers for the 21% market share, Acer and Dell were 18.9% and 12.7%; the Acer and Asustek Internet for the market share of 32.4 percent, respectively, and 26.7%.


Canada to use nanotechnology to develop new lithium-sulfur battery

Canada to use nanotechnology to develop new lithium-sulfur battery

The article come from

Sony laptop battery,

Researchers at University of Waterloo, Canada May 18 said they made more than a traditional large capacity lithium battery 3 times the lithium-sulfur battery prototype. The date of the relevant research published in the “natural materials” online magazine.

Lithium-sulfur batteries have a very broad application prospects, chemists have therefore conducted the study over the past 20 years. Sulfur and lithium is considered the most ideal material for a battery, these two chemicals in combination can not only provide high energy density, stability, security and better life also. In addition, the cost, the price of sulfur is also far lower than current lithium batteries are widely used in the other materials.

However, the manufacture of cathode battery problems has been a major problem of people,PCG-Z505 , partly responsible for the charge and discharge and release of electronic storage, in which reversible electrochemical reaction in order to achieve a higher current, which must be similar to the sulfur and carbon Such a conductor in close contact, and after a very effective way to no.

University of Waterloo professor琳达纳扎尔research team led by technology through the nano-carbon and sulfur close integration. They used in the experiment is known as a porous carbon mesoporous carbon material. In the nano-level, this type of carbon in the pore size and pore volume is very consistent. Through nano-technology, the group will produce a hollow carbon tubes, each 6.5 nanometer thick, 3-4 nano-aperture. Sulfur may be due to heating and melting, when the exposure to carbon nanotubes after they are inhaled and solidification contraction for sulfur nanofibers. Through electron microscopy studies on the perfusion of the carbon nanotubes have sulfur profile inspection found that in all of the aperture in both full of sulfur,PCG-V505, carbon and sulfur to achieve a perfect combination.

Nazarbayev said that by such a composite material made of battery power by up to 80% of the theoretical value, but also in maintaining a lower cost, good stability and a better circulation of the premise, its energy density than traditional lithium - transition metal oxide cathode of the battery into the high-3 times. This porous carbon materials “sucked up” technology to other composite material also provides a new way. Study in the future they will also further improve the structure of such a cathode material and performance.

Global progress in standardization of automotive batteries

Monday, May 25th, 2009

Electric vehicles in the seminar “EVS24″ on a number of organizations have on the plug-electric hybrid (PHEV) with charging systems, and automotive lithium-ion rechargeable laptop battery to deliver a speech to the standardization. PHEV,PCG-R505, the International Electrotechnical Commission standard (IEC), International Organization for Standardization (ISO) and the United States mobile Engineers (Society of Automotive Engineers, SAE) were introduced in the standardization of their efforts, which include the standardization of specifications for connecting PHEV charging facilities and communication technologies and systems. Standardization activities of these bodies by German companies (ISO), French companies (IEC) and the American Enterprise (SAE) led the implementation.

Standardization of PHEV

IEC and ISO for the realization of PHEV charging facilities and the connection of the standardization activities carried out is aimed at reunification of the two groups of “IEC / ISO JWG V2G (joint working group vehicle to grid)” organizations. German energy company RWE AG famous Ingo Diefenbach on the progress of the work of the Organization delivered a speech.

IEC / ISO JWG V2G has two working groups (WG). One is related with the physical specifications of WG1. VGP-BPS8,Include specific work on the connector, cable, both the protection and power switch backplanes, such as 2P700 , 312-0279 , 312-0383 , 312-0386 , 312-3250 . In the more controversial aspects of the connector, IEC envisages only be used to connect charging devices and automobiles, and made the largest three-phase AC voltage 500V, 63A maximum current and terminal 7 (3 for power supply, one for ground used for the two signals, one for other purposes) and so on.

The other is related to communication technologies and WG2. Including the more secure methods of communication and communication services. Focus on the content while making it clear that the circumstances at the same time to determine the specifications Inspiron XPS M170 battery , as well as to ensure that the interconnected nature of the communication protocol. IEC / ISO JWG V2G will be summarized in the 09 years the results of the above topics and to develop the program, the mid-2010, intends to vote, to develop standards by the end of 2010. Although the IEC and ISO views seem more unified, but currently “there are still large differences” (Ingo Diefenbach).

On the other hand, research institutions in the U.S. Argonne National Laboratory (Argonne National Laboratory) on the Theodore Bohn progress in the standardization of SAE delivered a speech. PHEV standardization, SAE group generally consists of two specifications.VGP-BPS9, PHEV were used to connect the specification and infrastructure group,
