I came across a well-known social network to the manufacturer's website ... nuclear batteries
Well, so here is the news about the battery for a smartphone that does not require charging for up to 20 years. This was made possible thanks to the wonders of nuclear fission. But it is safe to assume that most users would be horrified, knowing that they carry radioactive material in their pockets. ')
The fact is that the active substance in the nuclear battery will be used tritium. Radiation caused by the breakdown of tritium is considered safe, and is not able to harm even the upper layer of the skin. The effect of radioactive tritium can be seen on the clock, which glow in the dark. The manufacturer claims that such a battery can withstand temperatures from -50 to 150, without noticing extreme fluctuations and also changes in height. Needless to say, having such a battery to charge your phone is a great success.
One such battery is capable of producing from 0.8 to 2.4V and from 50 to 300nanoAmper for 20 years.
