The rapid development of the international battery industry demand for a sharp increase of cobalt

At present, the use of cobalt metal production of cobalt salts and cobalt powder 10 enterprises have a total capacity of 1850 tons / year, the average annual domestic demand for cobalt in about 3000 tons, accounting for the total consumption of cobalt laptop battery 10%, is one of the world Cobalt sony battery, one of the main consuming countries.

China cemented carbide, diamond tools production accounted for first in the world, the consumption of relatively large cobalt, about 2,000 tons. Cobalt in the cemented carbide powder is mainly used in the binder, the average content of about 10%, consumption in China has reached 800 tons / year, accounting for the National Co-33% of total consumption, and nearly 5.4% per year rate increase.

In recent years, international and domestic battery as a result of the rapid development of industry, a sharp increase in the amount of cobalt powder. Since 2002, China's battery industry demand for cobalt powder has more than cemented carbide industry, become the largest consumer of cobalt industry.

Demand from foreign markets, since the 90's last century, the world's consumption of cobalt has been in an upward trend, with an average annual growth of 2.6%. In 1998 alone, the world's cobalt consumption reached 29,500 tons. According to the information reported in the next few years the world's cobalt powder to increase the consumption of about 8,000 ~ 10,000 tons, a sharp increase in usage.

United States: the use of waste water bacteria-powered fuel cell-sony vgp-bps2 battery, vgp-bps2a battery birth

Recently, the Pennsylvania State University environmental engineer Bruce Logan and his team invented a use of water to power fuel cells, and can purify the water supply project.

Battery is the core of the bacteria in the sewage. Bacteria in the decomposition of compounds in wastewater, it will have a certain amount of energy. Oxidation process will be the release of electronics, they are collected in the fuel cell will produce a small current. Now cup the size of model can generate enough current for the use of a small fan. Within a year or two, there are filing cabinets of the fuel cell the size of the emergence of a minute to purify a gallon of water, but also to a standard power supply of the family refrigerator.

In this experiment, a new power generation methods, and the bacteria of the fuel cell is very economical and practical, can be solved most people's needs.

NanoDynamics has developed portable solid oxide fuel cell

U.S. NanoDynamics, Inc. In Texas, San Antonio (San Antonio) at the "Fuel Cell Seminar" published on the development of portable solid oxide fuel cell (SOFC: Solid Oxide Fuel Cell). Will be propane gas (propane gas) for fuel, a fuel charge after about 24 hours a 50W output power.

Fuel cell known as the "Revolution 50". The company said that the fuel cell can be used to "carry soldiers and equipment to the supply of fuel, can be used as a portable rechargeable battery system, outdoor lighting and advertising systems, vending machines and power tools such as power" (the company's Chief Executive Officer Keith A. Blakely).

SOFC power generation is characterized by high efficiency, while operating temperature up to about 1000 ℃. NanoDynamics said ceramic materials through improved technology and module design, will be available at 600 ℃ ~ 850 ℃ lower temperature drive. On the characteristics of the product, the company said that the "unit of output per unit area density of 1W/cm2. Units the energy density of weight 3000Wh/kg" (Blakely).

Domestic fuel cell bus evaluation completed 3000 kilometers

From Dalian Institute of Chemical Physics, Chinese Academy of Sciences to develop the fuel cell engine has made significant progress, the second generation of 60kW proton exchange membrane fuel cell engine completed 150 hours of Tsinghua University hybrid joint debugging, loading the engine city bus to complete a total of 3000 kilometers mileage evaluation.

It is reported that the second generation of 60kW proton exchange membrane fuel cell engine used variable improved operation, Tsinghua University, completed in early 2004, integrated installation of city bus, driving the success of an urban traffic routes in real operation. Airport in Beijing, the vehicle-specific performance test vgp-bpl2 battery, and hp 372772-001 battery the fuel cell engine for rated output power of 60kW, the maximum net output power of 72kW, the maximum stack output power up to 94kW; fuel cell city bus mileage total of 3127km, a top speed of 70km / h, maximum daily mileage 303 kilometers, the test results are to achieve the desired goals, setting a national fuel cell city bus new record.
