  1. Nickel-cadmium batteries (Ni-Cd)

    2. It is used in laptop batteries for Sony np-fa50 in the veteran, but because it has a serious memory effect as well as the anode material used in nickel (Ni) on the environment will be toxic and cause pollution, so it is quickly was despise laptop, and replaced by a more superior nickel-metal hydride batteries.

  2. Nickel-metal hydride batteries (Ni-MH)

    3. the structural principle of nickel-metal hydride Sony np-f750 batteries is same with nickel-cadmium batteries , but it replaced the cathode by performance better, more environmentally friendly non-toxic nickel – metal hydride materials. Although only a small change, but it has brought a dramatic increase in performance. It also has an unmatched to make the advantages of nickel-cadmium battery is memory effect was not obvious, so that so that we no longer have the memory effect for that nasty trouble and become more user-friendly. Although the performance of nickel-metal hydride batteries for Sony np-fa70 are very good, but with technological advances, it is lighter in weight and a higher energy density lithium batteries replaced, become the laptop battery in the history of deadwood.

  3. Li-ion battery

    4. Many people think that lithium Sony np-fc11 battery means that we are now commonly used in lithium-polymer battery, in fact, lithium batteries, including lithium metal-ion battery (Li-MO2) and lithium-polymer battery (Li-ion) are two. Because Li-MO2 cells to enter the market in 1989, caught fire when the explosion occurred while the die, so it will soon disappear from people’s sight, replaced by a safer lithium-polymer battery. It is light weight, in the same capacity under its nickel-metal hydride battery for Sony np-ff50 weighs only about 1 / 2, so it is fast becoming the new darling of mobile portable devices have been used in most notebook computers, is now the backbone of notebook batteries.

  4. Fuel Cell (Fuel Cell)

    5. Fuel cells are the future of laptop battery star, it has many types, including proton exchange membrane fuel cell (PEM), alkaline fuel cell (AFC) and solid oxide fuel cell (SOFC) and many other However, due to the fuel cell start-up time and operating temperature and other reasons in fact suitable for notebook computer use only the fuel cell proton exchange membrane fuel cell (PEM). PEM fuel cells for Sony np-ff70 using methanol fuel, from the positive and negative electrodes composed of the principle of its power generation is the result of the methanol, after re-enter the negative hydrogen and oxygen enter the cathode, through the catalyst, hydrogen atoms into protons and electrons, by different paths into the cathode, e-cycle to produce electricity through an internal, proton through the electrolyte to achieve positive, combined with oxygen to produce water and electrical and heat.

    The experts agreed that restricting the commercial application of fuel cells, the biggest factor is the fuel Sony np-fh70 cell to use the metal platinum (Pt) or platinum as catalyst to make the cost of production has been high, the current production cost of the fuel cell 500 ~ 1000 USD / kW. Research shows that only when the fuel cell production costs fell to 50 U.S.dollars / kilowatt level can be truly accepted by consumers. The high cost of fuel cells is mainly due to mass production has not been formed, once entered mass production stage, the price of fuel akku will certainly be greatly reduced.

Sony Laptop Battery Problems

Sony laptop fujitsu fpcbp155 battery problems led the half-year operating profit plunged

Japan’s Sony Corporation 26, Xinhua reported, as the world’s major PC makers to recall Sony manufactured notebook computer lithium batteries, 2006, the first half of fiscal year (April to September of this year), the company’s operating profit plunged 90.9 year on year %, to 62.2 billion yen (one U.S. dollars approximately ¥ 119).

Showed a profit, Sony Group’s production of LCD TVs and digital cameras sales strong. Affected by the first half of this fiscal year, Sony’s sales revenue grew by about 10%, or about 3.6 trillion yen.

Because Sony manufactured notebook computers fujitsu fpcbp155ap overheat and catch fire risks on a global scale is the total number of recalled batteries are expected to reach 9.6 million. This incident led Sony to recall bear the more than 500 billion yen in costs.

Sony also lowered the company’s 2006 fiscal year (ending March 2007) had a profit forecast. Company’s net profit to fall to ¥ 80,000,000,000, compared with the previous fiscal year fell 35%; operating profit of 500 billion yen, compared with the previous fiscal year decreased by 78%.

Earlier at a press conference, Sony’s vice president Yutaka Nakagawa for the first time on the notebook computer batteries and related services to the customers all public apology.

“Battery Door” storm undetermined Sony will again be the United States judicial investigation

Also caught “the battery door” of the Sony company has heard bad news fujitsu S26391-F6120-L470, Sony said Tuesday, because of SRAM (static random access memory) market alleged existence of monopolistic behavior, its U.S. subsidiary is receiving the U.S. Department of Justice investigation.

Sony said in a statement, the U.S. Justice Department asked the company to the Ministry of Justice is currently providing detailed data on Sony’s SRAM business. Sony said it would fully cooperate with the U.S. Department of Justice investigation, but declined to disclose details of the investigation.

SRAM chips provide high-speed data transfer is a kind of memory chips, are widely used in networking, telecommunications and computer and other electronic devices with fujitsu SMP-EFS-SS-22E-06. This year in October, the U.S. Justice Department has announced SRAM suppliers to investigate anti-competitive behavior. The agency with the Cypress, Mitsubishi Electric and Samsung made contact.

Recently, Sony has been due to laptop battery recalls, new product and other problems delayed the release of wrangling, the investigation of the SRAM, the company will undoubtedly face more trouble. Earlier South Korea’s Samsung Electronics and other companies for Fujitus Battery, but had conspired to have been charged the price of DRAM and eventually fined more than 731 million U.S. dollars.

In recent years, the United States, Japan, Europe, the leaders of the developed countries have to express their views in support of hydrogen and fuel Sony np-fh100 cell technology development. Although fuel cell technology has made great progress, but compared with the industrial demands a lot of work to be done, mainly for the following five aspects:

  1. The need to further improve the adaptability of fuel xps m1710 battery vehicles in different climatic (eg, high or low temperature region), in different environments (such as high altitude, dust large areas of poor air quality) and different traffic conditions (such as frequent changes in operating conditions or Kai frequent stops working conditions, etc.), the flexibility.
  2. Reliability and durability of current fuel cell stack life of only about 2000h, the current Beijing demonstration fuel Jvc bn-v428 cell buses running on an average intact rate of 92%, while diesel vehicles up 99.16 percent; fuel cell vehicle failure rate than Traditional car high, it is necessary to further improve the reliability of fuel cell vehicles and durability.
  3. The total energy efficiency fuel Dell xps m1730 battery stack operating temperature can improve the energy conversion efficiency of fuel cells in 2006, has been increased to 90-95 ℃, and – once high-temperature membrane (working temperature 120 ℃ above) successfully developed fuel cell technology There will be a fundamental breakthrough. In addition, a variety of hydrogen production, hydrogen storage of new technologies are also under development.
  4. Cost in 2006 Toyota has developed a new type of proton membrane target price of only 10 U.S. dollars / m2; the more expensive platinum catalyst layer with nano-technology research is under way. In addition, fuel xps m1330 battery components has been developed a variety of specialized technology companies and special parts and components companies, so as to improve the reliability and durability, improve performance and reduce costs to create conditions.
  5. Infrastructure supporting the building of infrastructure, lack of industrialization is also a need to address the problem. Such as hydrogen refueling station, maintenance, spare parts supply, need to gradually expand and promote, which requires several decades of time.
    Hydrogen and fuel vostro 1500 battery l automobile technology development is a risky strategy of choice, one should not be overlooked and missed with a risk of technological innovation and leap-forward development opportunities. At the same time, fuel cell vehicles for car manufacturers is a strategic high-tech products, automobile manufacturers should further improve the fuel-cells vehicle technology, with a view to grasp the initiative in future market competition.
