SCIENTISTS HAVE DEVELOPED A HIGHLY COMPACT NUCLEAR BATTERIES
Researchers at the University of Missouri state that prototyped compact nuclear batteries aqueous based whose efficacy and duration of much higher as compared with conventional batteries. Scientists believe that in the near future, this type of battery is used in a variety of fields, including the production of cars and even spacecraft, as well as in those areas where efficiency, reliability and duration of these energy carriers will have the highest value.
“Betavoltaika – production technology batteries that generate energy from radiation – is the subject of research as a potential source of energy since the 1950s,” – says Associate Professor of the College of Engineering at the University of Missouri Jay W. Kwon.
“Controlled nuclear technology may not necessarily pose a risk. The fact is that nuclear technology has long been used for commercial purposes and are often found in our homes. Nuclear technology, for example, used in fire sensors or the same signs emergency exit systems in buildings. ”
Using radioisotope strontium-90 to increase the efficiency of the electrochemical energy in a solution of a water-based researchers used as a catalyst for the decomposition of water based on nanostructured electrode of titanium dioxide. Catalyst and radiation are used to split water into oxygen compounds.
As a result, when the beta-radiation passes through the nanostructured titania (or platinum) in the titanium dioxide formed electron-hole pairs which create the flow of electrons, and finally the electric current.
“Water plays a role of a buffer, and form surface plasmons very positive impact on improving the efficiency of these batteries,” – says Kwon.
“As used ionic solution copes well with the work at low temperatures and can have a wide potential applications, including the production of automotive batteries (with proper assembly and packaging), and perhaps even in the aerospace industry.”
In fairness, it should be noted that this is not the first successful attempt to create a compact nuclear batteries (in 2012, for example, the company has created nanotritiumovye City Labs battery), but this is the first successful example that demonstrates the effectiveness and benefits of radiolysis (water splitting radiation) for production of electrical current at lower temperatures. In addition, scientists from the University of Missouri say that their method of splitting water to produce energy is more efficient compared to similar methods proposed by other research teams.
Scientists Missouri University explain the fact that, unlike other methods photocatalytic splitting of water to produce the energy of the battery by producing a water-free radicals, which are recombined or trapped water molecules and are due to the radiation (and the use of the titanium dioxide / platinum) to be converted into electricity. The process of water splitting, even at room temperature more efficiently than before.
In the same cells solar cells use a similar mechanism for the transfer of energy by means of electron-hole pairs. However, it produced very few free radicals, because the photon energy exists mainly in the visible region of the spectrum and therefore at lower energy levels.
In turn, beta radiation, obtained by strontium source, thanks to its ability to accelerate chemical reactions involving radicals and the higher energy level of the electrons, is a more efficient way to produce a reliable and long-running source of energy. So effective that once nuclear battery water based can be a suitable alternative to solar cells and treated as a reliable source of energy with low levels of pollution.
