Successful manufacture of long-life, high-performance radioactive batteries

The University of Missouri has just announced a successful production of a battery system with a long life and far higher efficiency than current battery technology. The above battery system promises to be applied to many different fields such as transportation, aerospace, . and many other high-tech science fields.

Professor Jae W. Kwon - leading the research team said: " Betavoltaic is a battery technology that generates energy from radioactivity and it has been studied since the 1950s. Radiation control techniques are no longer available. We have many commercial applications that apply radioactive technology in our lives, such as fire alarms in bedrooms or on escape symbols using Tritium (a heavy isotope of Hidro) to luminescent".

By using radioactive isotope Stronti-90, the researchers have turned a titanium dioxide nano-electrode into a catalyst that enhances the process of water resolution to help electrochemical energy be generated more. Accordingly, the catalyst will assist in breaking the bond in the water molecule, turning into oxygen compounds and emitting nuclear radiation. Next, high-energy beta radiation will penetrate the nano-sized holes on the titanium dioxide electrode, the pairs of electron holes will be formed and generate the electron displacement flow. The end result is that the current will be generated.

However, this is not the first radioactive battery system to be built. Previously, City Labs used to create the first radioactive battery model. Nevertheless, the model of the University of Missouri researchers is more promising and promising due to the use of radioactive dissociation techniques (radioactive water splitting) to generate electricity. At the same time, the process also produces low temperature and much higher efficiency than previous approaches.

According to the team, the reason is that during the process of radioactive water separation, high-energy beta radiation produces free radiation inside the water environment. After that, the kinetic energy will combine or be trapped in the feces from the water. Finally, the radiation will be converted into electricity using titanium dioxide electrodes effectively at room temperature conditions.

The successful manufacture of the above radioactive energy battery system has created a premise to apply to many fields, especially high-tech research industries such as aerospace, which need a stable, high-performance energy source and durable in many harsh conditions. At the same time, this is also a bright and feasible candidate with solar energy to create stable, environmentally friendly energy sources in the near future. Research has been published in the recent issue of Nature.
