The magnitude and speed of energy released by nuclear battery when it decays are not affected by temperature, chemical reaction, pressure and electromagnetic field in the external environment. Isotopes powered by nuclear batteries work for a very long time, which may even reach 5000 years.

2. Disadvantages:

Radioactive pollution must be properly protected; Moreover, once the battery is installed, whether it is used or not, with the decay of radioactive sources, the electrical performance will decline.

3. Principles

It is understood that when radioactive substances decay, charged particles can be released, and if used correctly, current can be generated. Usually unstable (radioactive) nuclei will decay and become more stable after emitting particles and energy. Nuclear batteries are made by using the principle that radioactive materials will release energy when they decay. Nuclear batteries have been used in military or aerospace fields before, but they are often large. In the past, a major difficulty in battery research and development was that in order to improve performance, the size of the battery was often larger than the product itself. The research team led by Quan Zaiwan, a professor of computer engineering at the University of Missouri, successfully slimmed down the "nuclear battery" and developed a small but powerful "nuclear battery". The nuclear battery developed by Professor Quan Zaiwan is only slightly larger than 1 cent coin (diameter 1 .95cm, thickness1.55mm), but its power is ten thousand times that of ordinary chemical batteries.
