• What is Betavolt?
Betavolt is a Chinese company claiming that the new atomic energy battery can generate electricity stably and autonomously for 50 years without charging or maintenance.
• How does a betavoltaic work?
A betavoltaic device directly converts beta particles (electrons) from a beta-emitting radioactive source into electrical energy. This is accomplished through a p-n junction conversion similar to that of a photovoltaic (PV) cell.
• What is the lifespan of a betavoltaic battery?
A betavoltaic battery has an energy density that is 102 to 104 times. higher than that of chemical or fossil fuels. It has a long lifetime potential of several tens of years to several hundreds of years.
• What are the sources of betavoltaic power?
A betavoltaic device (betavoltaic cell or betavoltaic battery) is a type of nuclear battery which generates electric current from beta particles (electrons) emitted from a radioactive source, using semiconductor junctions. A common source used is the hydrogen isotope tritium.
• What is a betavoltaic energy conversion?
Betavoltaic energy conversion refers to the generation of power by coupling a beta source to a semiconductor junction device. This paper briefly reviews the theory of betavoltaic energy conversion and some past studies of the subject.
