New "nuclear battery" will be published ten times the power available to more than ten years (Chart)
May 14, according to U.S. media reports, this week, scientists announced the development of a new type of "atomic batteries", the battery from the radioactive decay of nuclear material to drive, its power is similar to other cells 10 times, but also for the work of more than a decade.
In the cell there are many family members can be generally divided into chemical acer batteries and physical toshiba batteries battery two broad categories. Chemical batteries include batteries, battery, fuel cell, micro batteries, metal - air batteries and so on; physics of solar cells and batteries are two types of radioisotope batteries.
Silicon to capture radioactive gases from the electricity generated by silicon to capture radioactive gases generated by the electronics, such as tritium. Solar cells in this way will be the same sunlight into electricity are similar.
But so far, the efficacy of this new type of battery has not reached the level of solar cells. The reason is simple: when the decay of radioactive gas to start when it is not the focus of electronic radiation to one direction, most of which are missing.
Researchers presented, that have been carried out more than 50 years will be converted into electrical energy attenuation of nuclear energy research, but this has been the effectiveness of the conversion is not high. Now develop a more effective way of conversion, the researchers hope that this way we can create a new type of batteries to provide power long.
R & D staff, this extraordinary battery life make it suitable for application to a number of surgical devices, such as cardiac pacemakers, or for the spacecraft and deep space probes to provide electricity.
Perhaps in the next few years, in your own home you will find from these battery-powered sensors and other small devices. These devices typically consume less energy, but the use of traditional batteries, frequent replacement will make you a headache. Scientists said the new battery can be used more than ten years, and has passed the relevant test.
At present, the more successful is the fuel cell acer lcbtp03003 battery, acer travelmate 4000 battery, acer travelmate 3000 battery. Usually fuel cell to hydrogen, methanol, methane, formaldehyde as fuel, oxygen, air, hydrogen peroxide as oxidant. Fuel and oxidizer through the catalyst, electrode, respectively, in two oxidation and reduction reaction occurs.
Fuel cells and batteries or other means of power generation in general, it is characterized by the greatest efficiency, usually ranging from 60 ~ 80%. In addition it is no noise, less pollution, power range, from tens of milliwatts to tens of thousands of kilowatts. Therefore, the fuel cell has now been widely applied to space communications equipment, submarines, and no one to take care of the occasions, such as navigation, weather stations and other places.
In recent years, Japan has also successfully developed a kind of paper is also thinner than the ultra-thin battery. This size of battery 2 to 4 millimeters, the thickness of only 0.034 millimeters, about half the diameter of the hair. Ultra-thin battery charge and discharge can be repeated up to 2000 times a charge can be used 200 to 300 hours, and provide the basic stability of the voltage of 2.5 volts. It can be affixed to the inner layer of solar cells, rechargeable batteries during the day using solar energy, solar cells to discharge at night, it can be said is a "permanent" battery.
"2005 China's energy and power batteries and its key materials Symposium," the curtain in the Central South University
May 13, by the Chinese Materials Research Society, the National 863 high-tech experts in the field of new materials, the Commission, the National Natural Science Foundation sponsored Engineering and Materials Engineering, Central South University hosted "2005 China's energy and power batteries and its key academic seminar materials will be "kicked off in my school. Tang, deputy director of Hunan Provincial People's Congress Standing Committee of entitlements, Hunan People's Political Consultative Conference Vice-Chairman Yang Baohua, the Chinese Materials Research Society Academician Zhou Lian, chairman, president of Central South University, the National 863 high-tech experts in the field of new materials, HUANG Bai-yun, director of Academy of Sciences Committee, academicians He, Yang sound, smell immediately, DAI Yong-nian, Li-Quan Chen, LIU Ye-xiang, QIU Guan-zhou Vice-President, Chen Yuan and the National Science and Technology, National Development and Reform Commission, the National Natural Science Foundation Committee and other relevant ministries attended the Science and Education Building in the morning at the International Hall pa3356u-1brs battery, pa3356u-2brs battery, pa3356u-3brs battery the opening ceremony.
Huang Boyun schools principals on behalf of the delegates to extend a warm welcome and hope that through this workshop to further unite the country with the power battery energy storage material of the research strength of the field, and jointly promote China's battery and power storage batteries and the development of related materials for national scientific and technological development and make greater contributions to economic construction. Tang, deputy director of Hunan Provincial People's Congress Standing Committee of entitlements, the Chinese Materials Research Society Academician Zhou Lian, chairman of the meeting also made a statement.
The Symposium on China's energy policy, energy and power batteries and its key materials, hydrogen, solar and wind power can be green renewable energy development and application of a five-day academic exchange activities. The meeting will showcase China's hydrogen energy, solar cell and battery materials and technologies of the latest research results, analysis of China's battery research and production materials, and explore our new energy and renewable clean energy development strategy. Special report of the seminar papers 22, 161 academic papers, from the relevant ministries, universities, research institutes and enterprises, experts and scholars up to toshiba satellite a50 battery, toshiba tecra a3x battery 200 people.
