Nuclear battery produces power for 50 years without needing to charge The battery in the image is a betavoltaic battery, also known as a nuclear battery. It is a type of battery that uses the energy from the radioactive decay of tritium to generate electricity. Tritium is a radioactive isotope of hydrogen that has a half-life of 12.3 years. This means that half of the tritium atoms in a sample will decay into helium atoms in 12.3 years. As the tritium atoms decay, they release beta particles, which are electrons or positrons. These beta particles can be used to generate electricity in a semiconductor material. Betavoltaic batteries have several advantages over conventional batteries. They have a very long lifespan, typically 50 years or more. This is because the half-life of tritium is much longer than the lifespan of the chemicals in a conventional battery. Betavoltaic batteries are also very reliable and can operate in extreme temperatures and environments. However, betavoltaic batteries also have some disadvantages. They are more expensive than conventional batteries and they produce a small amount of radiation. The amount of radiation is very small and is not considered to be a health hazard. However, it is important to handle betavoltaic batteries with care and to dispose of them properly. Betavoltaic batteries are used in a variety of applications, including medical devices, pacemakers, satellites, and other long-lived devices. They are also being investigated for use in electric vehicles and other applications where a long lifespan and high reliability are important. The specific battery in the image is a Betavolt Model BV100. It has a maximum activity of 50 Ci (curies) and a lifetime of 50 years. It is manufactured by Beijing Betavolt New Energy Technology Co., Ltd.
