Introduction to Betavolt Technology’s Nuclear-Powered Battery
A Chinese company, Betavolt Technology, has developed a nuclear-powered battery, the BV100, which it claims can last for 50 years without recharging.
Prototype Design and Energy Conversion
The coin-sized prototype harnesses energy from nuclear isotopes and employs semiconductors to convert this energy into electrical power.
Potential Impact on Consumer Electronics
The company suggests that the battery’s extended lifespan could enable devices like smartphones to operate indefinitely without recharging.
Performance in Extreme Conditions
The BV100 is also said to perform well under extreme conditions, operating safely in temperatures ranging from -60 degrees centigrade to 120 degrees centigrade and resisting punctures and gunfire without catching fire or exploding.
Plans for Mass Production and Upcoming Versions
The company plans to mass-produce the battery by the end of this year and introduce a 1-watt version next year.
Nuclear Isotope Technology and Operational Lifespan
The nuclear battery uses isotope technology, capturing energy from the nuclear decay of radioactive elements.
The BV100 utilizes nickel-63 as its radiation source, which has a half-life exceeding 100 years, ensuring it stays operational throughout its 50-year lifespan.
Innovative Semiconductor Development
Betavolt’s researchers developed a unique single-crystal diamond semiconductor, using boron-doped diamond as a substrate and a plasma chemical vapor deposition method to create the diamond semiconductor converter.
Safety and Environmental Concerns
While the BV100 offers promising applications, concerns have been raised regarding nuclear safety, control, radiation protection, and potential radiation damage to semiconductors.
Challenges in Designing Nuclear Batteries for Small Devices
Meanwhile, designing nuclear batteries for small electronic devices like smartphones and drones has been challenging, as these concerns need to be addressed.
Recycling and Environmental Impact
Recycling considerations also emerge due to the long lifespan of nuclear batteries, although Betavolt plans to record and recycle each battery, with the nickel-63 decaying into non-radioactive copper-63, posing no pollution threat.
Betavolt’s Place in the Trend of Nuclear Battery Development
Betavolt Technology’s BV100 is part of a broader trend in the development of nuclear batteries, with the US based company CityLabs also working on betavoltaic batteries using tritium isotopes since 2010.
Tritium as a Safer Radiation Source
Tritium is considered safer due to its easily blockable radiation.
Practical Applications of the BV100
However, the BV100 aims to provide a practical and efficient solution for various applications, including aerospace, pacemakers, and electronic devices.
