City University of Hong Kong developed a non-radiation of wireless battery charging platform
According to media reports in Hong Kong City University of Hong Kong Department of Electronic Engineering developed a wireless vgp-bps5 battery, vgp-bps5a battery, m8416g/a battery, apple ibook g414-inch battery charging platform, through the plane of the electromagnetic waves emitted can be for different types of electronic products charge, the process do not have access lines, mobile phones can be used in the initial, MP3 and PDA products.
City University said that as the electromagnetic wave can only be received at close range, there will be no radiation, it is estimated that each charging platform is priced at about 300 yuan.
Beijing this fall will be like homemade hydrogen fuel cell car
Changchun City, Jilin Province Some experts suggested that the current development of automotive fuel cell projects, can also be energy-saving environmental protection, and to seize opportunities in the international community and broad prospects.
Experts said that the fuel cell project is within the 863 projects planned, at present, Tsinghua University a1079 battery, Tongji University and the Dalian Institute of Chemical Physics ongoing research. This autumn, Beijing China and the United States will be made like the hydrogen fuel cell vehicles.
The key to fuel cell technology is the hydrogen proton exchange membrane, Changchun City, Jilin Province Institute of Applied Chemistry, has ion-exchange membrane technology, not the lack of hydrogen materials in Changchun. In June this year, Chery Automobile has become the Ministry of Science and Technology took the lead in the first “National Energy Saving and Environmental Protection Research Center of Automotive Engineering,” the base.
Fuel cell is an energy-saving projects, 34% overall efficiency is the efficiency of petrol-driven 3 times 6y270 battery, c1295 battery; At the same time, the fuel cell is an environmentally friendly project, which can achieve zero discharge of pollution, chemical reactions produce only water objects. In national energy security strategy and oil bottleneck constraints, this project has broad prospects.
Experts believe that a fuel cell project is related to the national energy strategies and catch up with world’s advanced level, a major event for its own intellectual property. In the development of this project, at home and abroad rather close in time. At present, China has not lagged behind the targets, the State also funds support, should be similar to the Changchun-based FAW and by such a unit, should be positive for the project.
Nickel-hydrogen battery R & D success
Xi’an Jiaotong University has successfully developed a light weight, long life, high energy density, non-environmental pollution m8433 battery, a1008 battery, apple ibook g412-inch battery, and fast charging and discharging of the nickel-hydrogen batteries advantages.
Nickel-hydrogen battery has become the world competing for research and development of new energy. Its capacity is double the ordinary lead-acid battery with high current release red, no memory effect of a series of advantages. It is understood that the nickel-hydrogen batteries for electric vehicles is the development and application of the process of practical application of the power source. With the development of environmental protection for rechargeable batteries called for increasing the battery has good prospects for development of applications.
Magic change coal direct battery power to learn the only way to non-combustion
At present, the scientists developed a new type of coal for fuel cell energy. This battery and traditional methods of coal is not only simple to extract the energy of combustion, so that the utilization of energy has been a substantial increase.
Vibert Douglas, Harvard University, said: “The battery’s basic idea is to find a method of chemical energy in coal directly into electrical energy.”
Vibert said traditional coal burning power plants through the heat, using heat to promote the steam turbine to produce electricity. During this process, 65% of coal energy will be lost.
Prior to this, people will be struggling to find a kind of coal used for fuel cells, but in order to achieve this process must have a temperature of 600 ℃ to 900 ℃ between the dissolved carbonate electrolyte. However, such a high temperature not only to reduce the use of efficiency, but also make it easy to battery corrosion.
Vibert’s new design and allows the temperature at 100 ℃ under power, the temperature of the previous requirement to achieve this temperature is much easier. However, battery energy utilization in the samples was surprisingly low, only 7%. The utilization rate of only traditional methods of one-fifth of the utilization of coal a1175 battery, apple macbook pro15 battery.
This battery is Vibert George White and his colleagues jointly developed by Sezgin. They add toner slurry of iron ions, and then in sulfuric acid from the mixed electrolyte into the battery. In the mixture, the ferric ion by carbon reduction in the fuel cell in a typical reduction – oxidation cycle, resulting in power.
However, Vibert said that because coal is the source of energy for the battery, this battery can not avoid greenhouse gas carbon dioxide. However, if the battery energy utilization by improving the utilization of power plants can not exceed, then the people from the coal seam is widely distributed throughout the world to gain more energy, but also will not be accompanied by the increase of carbon dioxide emissions.
Vibert said, in fact, only very simple and easy to see improvements in battery energy can be greatly improved utilization. For example, the use of higher quality coal, or improvements in the design of the electrode, the electrode _ is taking a closer.
In this regard, the Royal London School of Energy Policy Management Group Matthew Leach said that such improvements to make fuel cells for the opportunity to compete with traditional coal-fired power generation is critical.
Leach also said that such a battery will be used for large-scale power generation units, we should not be attributed to it can be used in the type of car-MH battery. However, he also believes that the advantages of fuel cells is one of the true portability, and this a1078 battery, a1148 battery, apple powerbook g415 inch battery because it is difficult to make a mixture of pulverized coal with sulfuric acid and restricted distribution.
