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.

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.
