Not-for-life nuclear batteries ultra-thin display of foreign scientists
Nuclear batteries are often used in military or aerospace technology, but usually larger. Now the University of Missouri research team of foreign claims, only the appearance of a coin the size of the battery life of up to 100 times normal miniature "nuclear battery" has been developed.
Nuclear battery prototype
It is reported that they through the use of micro-and nano-scale systems developed an ultra-miniature power supply equipment, such equipment by the decay of radioactive substances, the release of charged particles, resulting in continuous current.
The research team said, although long before the nuclear batteries have been used in aerospace field, but because of size constraints, the earth, little application of nuclear batteries. Most nuclear batteries charged particles intercepted by solid-state semiconductors because the energy of particles is very high so the semiconductor will be over time damage the battery in order to allow long-term use, nuclear batteries are made very large.
The team developed a miniature "nuclear battery" with a liquid semiconductor, in the passage of charged particles will not cause damage to the semiconductor, so that they can further miniaturization of the battery. Dr. Jae charge of the project, said that although people always hear "nuclear" pale, but in fact has long been used in nuclear energy such as cardiac pacemakers, space satellites and submarine equipment, and other safe power supply projects.
