The battery design works for 100 years

Experts from the Russian National Research Nuclear University (MEPhI) are developing energy sources based on beta-volt energy sources using radioactive isotopes.

 This will lead to the production of safe nuclear batteries operating over a 100-year lifespan, serving many areas and especially medical, particular pacemakers and mini-devices to measure devices sugar level or blood pressure, systems and telemeter objects distant and small robots, as well as devices that operate independently for a long time, according to the press service of the university. The results were published in Applied Physics Letters.

Recent achievements in the field of nanoelectromechanicals and micro-systems, which combine in a single device electronic nanoparticles and mechanical elements such as transformers, pumps and motors, can be promising for the design of physics, biological, chemical or microscopic.

Scientists study the possibility of reducing conventional lithium-ion batteries, solar cells, fuel cells and various types of capacitors to combat the lack of micronutrient energy for small and nanomolecular systems that prevents the introduction widespread use of such devices. However, the size of these energy sources is still too big to be able to design very precise micro systems.

Radioisotope batteries

Radio-isotopic batteries are also nuclear batteries to serve very modern micro-systems, atomic batteries being the current sources in which the radial fission energy of semi-stable elements of nuclear nuclei is converted into electricity. These nuclei are characterized by a high energy density per unit mass and volume. The stable energy release period varies considerably in the selection of nuclides. Radioisotope batteries can operate for a long time and are stable, maintenance-free and noise-free.

The unique properties of nickel 63 today is the transformation that occurs on photoelectric energy and is the shortest way to convert nuclear energy into electricity. At the same time, scientists are doing intensive research on beta-volt sources of energy, which is gaining a lot of ground in practice.

The fact is that when using a mini-source with a radioactive counterpart, which emits a mild beta radiation, it will be easy to create a physical protection system for the user and the surrounding objects of the radiation. Therefore, these sources are promising prospects for civilian use.

Scientists at MEPhI University investigated the physical properties of nickel nanotube chip electrical current and selected the best experimental indicators to allow efficient beta power transformation for nickel 63 to electrical energy.

The radioisotope of the nickel-63 element is one of the most promising radionuclides in beta-voltaire, the source of mild beta radiation having a lifetime of 100 years. Nickel is therefore a unique element, suitable for sustainable energy systems that do not require high costs, and nickel is also a very good metal, flexible and relatively durable, and can be easily processed.

According to the researchers, improving the efficiency of current transformers for the energetic power of the beta-nickel-63 beta electrolyte, as well as the search for alternative physical systems, are very promising tasks in modern science.
