Infinite energy source
According to British technology news site Techradar, the battery is currently in the testing phase and Betavolt plans to mass produce it for use in commercial devices such as phones and drones.
Additionally, this nuclear battery can be used for aerospace equipment, AI, medical devices, sensors and micro-robots, according to the company.
Betavolt claims to have been inspired by nuclear-powered devices like pacemakers and satellites.
Betavolt is also planning to ramp up its technology to produce 1-watt batteries by 2025.
This technology could revolutionize electronics, by completely eliminating the use of portable chargers and creating devices that can run continuously for 50 years without degradation in power.
It also makes it safer for users, as the battery does not catch fire or explode in the event of an accident.
How does the battery work?
To create the nuclear battery, Betavolt scientists used nickel-63, a radioactive element, as the energy source and then diamond semiconductors as the energy converter.
The team grew a single-crystal diamond semiconductor just 10 microns thick, then placed a 2-micron-thick nickel-63 plate between two diamond semiconductor transducers.
The decay energy of the radioactive source is then converted into electric current.
Betavolt claims the advantages of nuclear power batteries are that they are lightweight, have a long life and high energy density, and can operate normally in extreme temperatures from -60 to 120⁰C.
Are nuclear batteries harmful to health?
Betavolt claims that nuclear batteries are safe because they do not emit external radiation. Currently, medical devices inside the human body such as pacemakers and cochlear implants also use a type of nuclear battery.
Betavolt says that after the battery decomposes, the 63 nuclear isotopes will become copper, which is non-radioactive and does not pose any threat to health or the environment.
