SAMARA, Oct 4 — RIA Novosti, Ekaterina Kalashnikova. Samara scientists are working to develop nuclear batteries that can run for 100 years, the press service of the Samara University in the name of the Queen.
“Scientists Samara, national research University named after academician S. P. Korolev has developed a technology that allows you to create a battery with a lifespan of over 100 years”, — stated in the message.
As the press service of the University, the technology is based on the idea of transforming the energy that is radiated by a radioactive source into electrical energy. A radioactive isotope emits a flow of electrons, and they generate electrical energy. Due to the emergence of electron isotope, which generates a source of beta radiation, scientists create analogues of the photoconverter, without using sunlight.
On the creation of power sources that would work due to the energy of radioactive isotopes, scientists are now working around the world. Experimental samples of nuclear batteries exist in Russia, and in Switzerland, and the United States. The advantage of development of the Samara scientists is that created on the basis of their technology product will be environmentally friendly, low cost and long service life.
These benefits are achieved through the use of new battery-powered carbon-14 as a radioactive source. The half-life of this element is 5700 years. Carbon-14 is non-toxic and has a low cost.
The second difference developed by the scientists of the Samara University is that as a “substrate” under a radioactive element uses a fundamentally new structure – a porous silicon carbide hetero-structure. An indisputable advantage of the silicon carbide structure is also its resistance to radiation. When radiation of the isotope remains practically unchanged, which allows us to say that the battery is manufactured in Samara, will work indefinitely (by the standards of human life) for a long time.
The scope of the “eternal” batteries in the first place, are “future technologies”. Due to its compact size, these power supplies are ideal for various kinds of sensors in automated systems of management and control, including for the continuous monitoring of oil and gas pipelines throughout their life cycle in remote regions of Siberia, the Far East and the Arctic.
Opportunities for the use of new batteries opened in medicine, particularly in cardiology. For cardioline acute problem of replacement of batteries in sensors of the pacemaker that sets the rhythm of the heart. A second operation can not stand all the patients, and often their lifespan is limited to the life of the pacemaker.
“The research scientists of the Samara University on the development of new technologies of batteries, working on the radioactive isotopes began a dozen years ago. Obtained patent on the technology the invention of new semiconductor structures for producing electric energy at the expense of radioisotopes. Obtaining a prototype of the new battery is scheduled for October-November this year”, — stated in the message.
