Battery "heart"
Hubei Province, electric cars in the "heart" - fuel cell research engine was a major breakthrough. Wuhan University of Technology before fuel-cell engine group revealed by the National Fuel Cell Engine sentinel laboratory testing, our province developed their own battery 25 kilowatts, "the heart", "jump" out of the leading domestic level. 115 kg weight group will be the "heart" of Shanghai Tongji University, made a special trip to the national fixed-point tested by the laboratory tests, 3 hours, 5 stood for the "final exams" passed. Cold-start from zero to full load operation, only 8.1 seconds. It is not only "feel" strong and continued strong in the full power of 25.11 kilowatts test cases, the continuous and stable operation of 30 minutes hp battery, current, voltage fluctuations do not, the two tests, such as the two horizontal lines, on-site testing personnel even referred to as the "true cattle. " The main points - more than the power density targets in 2005 the U.S. Department of Energy goals to reach the advanced international level of synchronization. Expert evaluation, this small size, high efficiency of the "heart", especially suitable for automotive power. This means that our province in the study of electric vehicles took a key step. In 2002, Dongfeng Motor Corporation 1000 funded, with Wuhan University of Technology to develop fuel cell vehicles, the Provincial Science and Technology Department, Wuhan Economic and Technological Development Zone has invested 1.5 million yuan, respectively, for their support. At present, the project has made significant progress. Equipped with the "heart" of the car-type features like cars, a total of 500 kilometers running test, the stability of the speed of 80 km / h, maximum speed of 110 km / hr.
Scientific experts believe that fuel cells will be in our province and a new bright spot in a high-tech to spur the development of a number of new industries.
In 2006 the first fuel cell vehicles to drive onto the city bus to the streets
September 16 Science and Technology Commission was informed that from the city: In 2006, the first fuel cell vehicles to drive onto the city bus to the streets; 2008, Shanghai will have more than a new type of environmentally friendly vehicles such component model car fleet, services the Beijing Olympic Games.
Fuel cell vehicles using hydrogen as energy source, non-polluting, low-power, low noise. Since 2000 the city was listed as a major scientific and technological project, its research and development process of concern, concept cars, "beyond those on the 1st," "beyond those II" has been published.
Why fuel cell vehicles into the first bus use? Experts explained that the fuel cell vehicle is an epoch-making changes in the automobile industry, the development of the high cost of "expensive car" directly into the market is clearly unrealistic. In before the official commercial operation, fuel cell vehicles need to cultivate a view through the market, the need for government procurement to support the bus is a better choice. At the same time, fuel cell vehicles need to support the construction of hydrogen refueling station, a fixed bus route, just building a small number of hydrogen refueling station can be, easy to operate.
Tongji University Automotive Institute Professor Yu Zhuoping, executive vice president of the Shanghai fuel cells made of the idea of the automobile industry. 2006 to 2007, Shanghai will have 100-class production capacity to form the model team, the construction of several hydrogen refueling station; in 2008 by the year 2010, will have production capacity of 1000-level, the composition of commercial fleet operators, the construction of several Hydrogenation of 10 points; in 2011 to 2015, will have production capacity of 10,000 level, the achievement of regional business, and the construction of hydrogen refueling station 100. Experts conservatively estimate that by 2020 fuel cell vehicles will reach the whole country 2.5 million, accounting for cars for more than 6 percent.
It is learned that the fuel cell bus project has been funded the United Nations in particular hp ex942aa battery, hp pavilion dv9000 battery, with a total funding amount of 100 million yuan. Similar projects in Cairo, Egypt, India, New Delhi, Shanghai and other Chinese cities in six developing countries at the same time. Some developed countries on the development of fuel cell vehicles are also very important to use. Volvo has developed two fuel-cell double-decker bus has been running in Berlin, 2012-2015 years Ford plans to achieve its commercial fuel cell vehicles, and in 2010 the Japanese planning to have 50,000 fuel cell vehicles and 500 hydrogen refueling station.
Large quantity of waste lead-acid missing, Kunming called for joint supervision of
Recently, the Kunming Environmental Protection Bureau of the city electric bicycle disposal of waste lead-acid batteries were investigated and found that the majority of electric vehicle manufacturers and marketers are not approved by the environmental protection department management of waste lead-acid batteries. Kunming did not deal with as a result of the local unit of waste batteries by manufacturers and marketers of the information provided by analysis of the city, about 80% of the waste lead-acid batteries to deal with Zhejiang Province, but no one can take the batteries out to specific data and accept the evidence of unit, while another 20% of the waste batteries will disappear without trace.
It is understood that Kunming will produce an annual 200,000 spent lead-acid batteries. Indiscriminate discharge of waste lead-acid batteries will not only seriously polluted soil and water resources, air pollution, destruction of ecological balance and at the same time, will endanger human health. Spent lead-acid batteries because of its chemical reactivity, has been included in "National List of Hazardous Wastes." However, in the survey, the vast majority of electric vehicle manufacturers, vendors, automotive manufacturers, such as battery used battery recycle should not apply for the units dealing with hazardous waste operating permit. To this end, the Kunming Environmental Protection Bureau of the city's electric bike market has taken a number of emergency control measures. Requirements of new entrants into the market of electric vehicles in Kunming manufacturer must provide operating permits, as well as hazardous waste and distributors used battery recycle agreement signed before the stock market registered its approval, has entered the market without a permit Kunming manufacturers to immediately re-submit At the same time, the province's enterprises require dealers to the provincial Environmental Protection Bureau as soon as possible to re-submit a permit application, but this work has appeared very difficult.
"The electric bikes are non-motorized, there are a large part of provincial and municipal electric bikes are not clearly settled in the market policy, a number of local environmental protection departments have also not included in the disposal of electric vehicles used battery recycle the scope of hazardous waste management." The survey carried out leading the environmental protection department, said: "As in many parts of spent lead-acid battery recycling and the application policy is not clear, electric car manufacturers in the province on whether the hazardous waste operating permit for not very clear, such as Kunming the transfer of the existence of a large number of different places of disposal of waste hp pavilion dv9100 battery, hp pavilion dv9200 battery, the urgent need for environmental protection departments in various parts of the establishment of linkage between the mechanism for recovery of reasonable norms of disposal of waste batteries.

Ultrafine nickel powder as the new darling of market
Ultrafine nickel powder as the new darling of market
In recent years, as a result of mobile phones, laptops batteries, computers and other telecommunications equipment for the rapid development of market demand for ultra-fine nickel powder has been rising. According to statistics, world demand for nickel-hydrogen dell batteries at an average annual growth of 20%, electronic products, multi-layer ceramic capacitors for ultra-fine nickel powder is very strong demand.
In order to meet the needs of the fast-growing market, the United States, Japan and other countries continue to invest huge sums of money to expand production of nickel-metal hydride. Kawasaki iron mining companies in Japan to invest 19 million U.S. dollars this year, its establishment in 1995 in Chiba Prefecture, the annual production capacity of 24 tons flour mill for ultra-fine nickel expansion, the plant is expected to yield the end of this year will reach 384 tons, becoming the world's largest manufacturers of ultra-fine nickel powder. International Nickel Company has also invested 14 million U.S. dollars to expand the British-based nickel refinery production capacity of battery materials, the plant produced a special powder products (ISP) to the output in 2004 will reach 400 million U.S. dollars. And, like other countries in the world, China's mobile phones, laptops, computers and the development of nickel-hydrogen dell inspiron 1721 battery is also very alarming, Tianjin base Ni-MH battery has been large-scale production and export, the country only on the nickel battery industry has been the demand for products A few years ago to 200 tonnes up to 4,000 tons at present, while domestic production of nickel powder in terms of yield or quality can not meet the market demand, especially in the production of ultrafine nickel powder, but also being in straitened circumstances.
Ni-MH battery products as a result of the stringent requirements and electronic products, multi-layer ceramic capacitor electrode technology needs, in addition to chemical composition, impurity content, such as ultra-fine nickel powder on the higher requirements, but also the physical properties of products, including powder particle size, surface properties, particle shape, a higher degree of uniformity requirements. China's nickel production technology and process equipment as compared with the developed countries there is still a gap, a result, many manufacturers in order to ensure the stability of the quality of its products, mainly imported raw materials for ultra-fine nickel powder, the domestic production and demand balance give us a topic worthy of study. If the analysis of nickel in China in recent years, the proportion of various sectors of consumption, it is easy to see that China's nickel consumption in the event of a fundamental change. China's metallurgical industry in 1999 with about 15,000 tons of nickel, nickel battery industry consumption 4000 tons, the industry spent nickel catalyst 5000 tons, 500 tons of nickel magnetic materials.
Nickel consumption over the past referred to as large as a result of the metallurgical industry developed slowly in a long time, nickel consumption growth lagged behind, while the rising star of the battery industry and the consumption of nickel catalyst for the industry at an alarming rate but the development of new industries to diversify the demand for nickel has shown a upward trend, the market has been "imported" by the occupation, a great pity. Domestic nickel production enterprises should seize the opportunity to change the planned economy period light weight of primary products markets, increased technological innovation, the introduction of foreign advanced technology and equipment, to fight for more market share.
The United States invented a new "dry" fuel cell hp battery as a gift.
Recently, U.S. researchers have invented a kind of work at a suitable temperature of the "dry" fuel cell, and low cost, easy to manufacture, the products of combustion is only water.
According to reports, the California Institute of Technology researchers invented this fuel cell to 160 ℃ in the work environment. It is by the cesium, hydrogen, solid-acid composition of "sandwich", the use of platinum as a catalyst. When the researchers will use hydrogen pressure pump into the cell, they found that the battery can produce a small amount of current and continuing for several days, the reaction product of only water.
The reason why this new type of battery known as the "dry" batteries, because it is only gas to generate electricity, is also a solid acid electrolyte. And low-temperature fuel cell is usually water and ethanol, such as by liquid electrolyte material to help generate electricity.
The researchers said that the shortcomings of the fuel cell is not producing electricity, the duration of short-term, and battery materials performance in extreme environments instability. Experts point out that only through extreme temperature tests, the fuel cell can have practical value.
