Small fuel cell market prospects: With the strong demand for practical use can not be long before
Lasted for a few years of fuel cells has ushered in a turning point in the development of heat. Fuel cells have been regarded as the largest automotive market, with the rechargeable 75uyf battery, 1691p battery, dell inspiron 2500 battery, dell inspiron 3700 battery and capacitor technologies, such as competitive force gradually, hybrid surfaced as a strong competitor. Practical fuel cell vehicle of the air like a mirage, as it seems very lopsided.
Fuel cells in electronic applications in the field of prospects to be? In Japan, as the most promising to meet the rapid growth in demand for mobile power technology, fuel cell has been the industry’s high hopes.
However, in previous fuel cells, as has been the other major aspects of the use of laptop computers, lithium-ion rechargeable batteries due to the continuous improvement of performance and power-saving technology is getting more sophisticated, battery-powered time is increasing rapidly. Recently, even up to 12 hours drive time of the product. This case the number of fuel cell is a bit worse.
In the absence of the local power outlet
Aircraft and even the future will also be equipped with the new Route outlet. There is absolutely no power to be a long time to use the local number of 10W power consumption of electronic products in Japan is almost hard to think of.
But on Earth there is a wide range of environment, in some cases, the fuel cell may play a decisive role. Among them, the army is the most typical.
The United States is currently based on “smart soldiers” the idea of stepping up to promote the electronic equipment of soldiers. Wireless communications equipment since Needless to say, such as a GPS (Global Positioning System) positioning of the PDA, night-vision goggles with protective glasses, as well as firearms with laser sight and so on, each soldier is now the average power consumption has reached dozens of W, after a few years is expected to reach 100W. Although the dell inspiron 3800 battery, dell inspiron 4000 battery, dell inspiron 4100 battery, dell inspiron 4150 battery capacity will be decreasing in the battle, but soldiers can not go back to the chariot in charge.
Although the army is only an extreme example, but a similar situation, as long as look at him, not entirely. Civil construction, agriculture, forestry, industry, police, security, airport maintenance division, as well as sports facilities, sports and television programs such as crew, to the use of IT technology and electronic technology for the major outdoor work in providing support, power naturally into an extremely important issue. In addition, hurricanes and typhoons in the affected areas may also come in handy.
The key is to have a strong market demand
Fuel-cell battery does not belong, but generators. As long as the continuous supply of fuel to generate electricity. Civilian living in the area of the dominant position of Japan, has always rigidly adhere to unknowingly in mobile phones, laptops, computers. If the start of limited use, so that fuel cells will inevitably lose its essential characteristics. In contrast, it is better to put it another way, that is small in size but with a strong market demand for a solid step by step the status of fuel cells.
In Japan, most of the integrated electronic manufacturers of new technologies to guide the process of utility, it will have to aim at the big market. For example, targeting the mobile phone first, the pursuit and then to adapt this technology, so it is easy to research gathered in the form of a passive direct methanol fuel cell up.
The development of new technologies and practical by a number of enterprises to bear the risk of the United States will first find out the small but strong market demand. And then go meet the diverse needs of the development of technology. Therefore, not too concerned about Japan’s technical approach, the United States is actively conducting research.
In fact, because of the above background, so I want to know what the risk of the U.S. fuel cell business to view. October 26 will be held to “portable electronic products with the latest trends in small-scale fuel cells,” the symposium titled, Millenium Cell has invited U.S. companies to deliver a keynote address JV Battaglini. Battaglini had been unique in the use of hydrogen generation device, to develop fuel cell market.
In addition, the conference will be invited to Japan, delivered a speech on the staff, and the holding of seminars. These companies include Toshiba DMFC (direct methanol fuel cell) field study of the world’s top Fumio Ueno, as enterprise customers over the years have been concerned about the development of fuel cell company Casio Computer Masaharu Shiotani, as well as its own technology the field of fuel cell Iwasaki of Seiko Instruments, such as clear text.
Oil prices set off a new high in China Li-ion battery technology has been a major breakthrough
In recent days, international oil prices set off a new high, reaching 70 U.S. dollars / barrel, the domestic oil prices are also quietly uplink. At present, much attention has been energy conservation, new energy materials development is mentioned again, in which the development of more mature material of lithium dell inspiron 8000 battery, dell inspiron 8100 battery, dell inspiron 8200 battery become more sought after by the market.
Physics, Chinese Academy of Sciences Fellow Xuejie Huang said: “China’s lithium-ion battery industry has developed very rapidly, has now become the world’s second largest producer of lithium-ion battery, second only to Japan. We have to do is the future development of large lithium-ion battery new materials, while reducing costs, but also more secure to allow the battery longevity. ”
Core technology R & D progress
Cathode materials for lithium-ion battery is currently the most costly material, but also a direct bearing on the safety performance of the battery and battery to achieve the possibility of large-scale, but traditional cathode materials - cobalt acid lithium has been the annual demand of more than 10,000 tons, thus led to sharp rise in price of cobalt, cobalt shortage of resources has begun to restrict industrial development.
It was heartening that can replace lithium cobalt nickel manganese cobalt cathode materials for lithium has been successfully developed. Xuejie Huang said: “This material is layered oxide cathode material, the last century, the early 80s was found that synthesis of the difficulty is much higher than lithium cobalt, crystal type is particularly difficult to control, has not been applied.” According to the briefing, by Huang et al Xuejie Study Group composed of the development of a unique precursor lithium synthesis and processing technology, 80% of the cobalt has been replaced by manganese and nickel, and the grain size of the control, composite materials to achieve the reversible capacity of 165mAh / grams of lithium cobalt than 10% higher over the life cycle to achieve 500 times.
In addition, the anode material is lithium-ion battery to assume a key function in lithium storage materials, the importance of the same can not be ignored. According to Huang Xuejie, currently applies to goods of graphite lithium-ion battery anode materials are reversible capacity of 300 ~ 340mAh / g. In response, researchers developed a hard carbon nanopore ball Lantern composite cathode materials, the reversible capacity of the material has reached 600mAh / g. At the same time, the development of nano-graphite fiber conductive additives can improve the high-power battery power density. It is learned that the only anode material is its research group has applied for 21 national invention patents, four of which are authorized, and has been authorized by the two international patents.
