Nuclear battery

A Chinese company claims to have developed a
coin-sized battery that works through nuclear decay, and could generate power for up to 50 years.

Quote:

The battery has a layered design, which will prevent it from catching fire or exploding due to sudden force. Betavolt also claimed that the battery is capable of working in temperatures ranging from -60 degrees Celsius to 120 degrees Celsius. Atomic energy batteries are environmentally friendly. After the decay period, the 63 isotopes turn into a stable isotope of copper, which is non-radioactive and does not pose any threat or pollution to the environment.

I believe the “63 isotopes” is a garbled version of “Nickel 63 isotopes”, which decays to the stable Copper 63 isotope, and has a half-life of 101.2 years.

Apparently, the level of radiation is safe to humans, and can be used in everything from pace-makers to satellites.

It all seems legit to me. Do anybody see a flaw, apart from the difficulty in obtaining approval?
