An atomic battery, nuclear battery, radioisotope battery or radioisotope generator uses energy from the decay of a radioactive isotope to generate electricity. Like a nuclear reactor , it generates electricity from nuclear energy, but it differs by not using a chain reaction .
Diagram of an RTG used on the Cassini probe. A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
Unlike traditional nuclear reactors, which generate heat and then convert it to electricity, betavoltaics offer non-thermal conversion. [ 11 ] A prototype betavoltaic battery announced in early 2024 by the Betavolt company of China contains a thin wafer providing a source of beta particle electrons (either Carbon-14 or nickel-63 ) sandwiched ...

Diagram of a MMRTG. The multi-mission radioisotope thermoelectric generator (MMRTG) is a type of radioisotope thermoelectric generator (RTG) developed for NASA space missions [1] such as the Mars Science Laboratory (MSL), under the jurisdiction of the United States Department of Energy's Office of Space and Defense Power Systems within the Office of Nuclear Energy.
Market Growth and Projections: The global nuclear battery market is projected to expand significantly in the coming years. According to a report by DataIntelo, the market is expected to grow at a compound annual growth rate (CAGR) of 10.5% from 2022 to 2030, driven by increasing demand for reliable and long-lasting power sources across various ...
An optoelectric nuclear battery [citation needed] (also radiophotovoltaic device, radioluminescent nuclear battery [1] or radioisotope photovoltaic generator [2]) is a type of nuclear battery in which nuclear energy is converted into light, which is then used to generate electrical energy.
Some Beta-M generators have been subject to incidents of vandalism when scavengers disassembled the units while searching for non-ferrous metals. [2] [4] [6] In December 2001 a radiological accident occurred when three residents of Lia, Georgia found parts of an abandoned Beta-M in the forest while collecting firewood. [4]
