What is the principle of nuclear batteries? Advantages and disadvantages of nuclear batteries

What are the advantages and disadvantages of nuclear batteries? What are the principles of nuclear batteries? When radioactive materials decay, they will release charged particles. If used correctly, these particles can generate electric current. Normally, unstable (i.e. radioactive) nuclei decay and become more stable as they release particles and energy. Nuclear batteries are manufactured using the principle of radioactive decay to release energy. Nuclear energy batteries have been used in military and aerospace fields, but they are usually relatively large. One of the important challenges of battery development in the past is that in order to improve performance, the size of the battery is often larger than the product itself. A research team led by kwonjae-wan, authorized by the University of Missouri’s computer engineering professor, successfully slimmed down the nuclear battery and developed a small but powerful nuclear battery. But the nuclear battery developed by kwon's team is only a little more than a cent (1.95 cm in diameter and 1.55 mm in thickness), but its energy is one million times that of traditional chemical batteries. The research team at the University of Missouri said that their goal in developing small nuclear batteries is to find suitable energy sources for micro-electromechanical systems, perhaps on the nanoscale. How to find a sufficiently small energy source device for micro- and nano-level electromechanical systems is a research hotspot, and micro-devices are also a research hotspot. Advantages and disadvantages of nuclear batteries Advantages: The amount and speed of energy released by nuclear batteries during the decay process are not affected by temperature, chemical reactions, pressure, electromagnetic fields, etc. The isotopes that power nuclear batteries can last a long time, perhaps as long as 5,000 years. Disadvantages: It is necessary to prevent radioactive pollution; once the battery is installed, whether it is used or not, its electrical performance will decline with the decay of the radioactive source.
