A Chinese company claims to have created a battery that outlasts the gadgets it powers. According to Beijing-based start-up Betavolt Technologies, the company behind the product, the nuclear-powered BV100 is smaller than a coin and can run for 50 years without requiring recharging.
According to the company, the prototype battery uses semiconductors to transform the energy released by nuclear isotopes into electrical power.
China announces the BV100, a nuclear-powered battery with a 50-year lifespan, marking the beginning of a new era of endless energy in a revolutionary development. The BV100’s betavoltaic technology, which makes use of nickel-63, opens up possibilities for a variety of uses, including deep-sea monitoring instruments that can withstand harsh conditions and military drones that can run continuously.
With China leading the way in sodium-ion battery technology, there is conjecture regarding the BV100’s possible influence on the electric vehicle (EV) market as it makes its debut. With its ability to provide an alternative energy source with benefits like increased safety, wider temperature tolerance, and possibly lower manufacturing costs, sodium-ion battery technology has the potential to completely transform electric vehicles.
The nuclear battery of the BV100 functions safely in harsh environments, ranging from 120 to minus 60 degrees Celsius, in contrast to conventional batteries. It is a flexible and dependable power source for a wide range of applications due to its resistance to piercings and gunfire without the possibility of catching fire or exploding.
The basis of the BV100 isotope technology, which was first introduced by British physicist Henry Moseley in 1913 and involves harvesting energy from the nuclear decay of radioactive elements. The battery utilizes nickel-63 as its source of radiation, taking advantage of the isotope’s longer half-life of over 100 years to guarantee continuous operation throughout its 50-year lifespan.
The BV100, which is categorized as betavoltaic, uses semiconductor junctions to directly produce an electric current from the beta particles released during the decay of nickel-63. Energy conversion efficiency is increased by using a special single-crystal diamond semiconductor that was created using a diamond substrate doped with boron. By connecting multiple modules, the BV100’s modular design—which places a nickel-63 layer between two diamond semiconductors—allows for scalable power outputs.
Although the BV100 provides access to a wide range of applications, developing nuclear batteries for tiny electronic devices continues to present difficulties. Radiation safety, nuclear safety, and possible semiconductor damage are among the issues. Because nickel-63, the radiation source used in the BV100, emits more radiation than alternatives like tritium, safety and recycling issues are brought up.
A major player is China’s Betavolt, which says it is the only company able to dope and produce large-scale diamond semiconductor materials. This discovery puts CityLabs in the US in competition as they have been creating betavoltaic batteries since 2010 using tritium isotopes. With the special qualities and possible uses of the BV100, China is leading the way in nuclear battery technology.
The lengthy lifespan of nuclear batteries presents recycling and environmental issues as Betavolt prepares to mass-produce the BV100. Although applications such as polar deep-sea beacons may not require recycling, existing use cases such as pacemakers and aerospace may encourage further research into sustainable battery disposal and recycling methods.
With the launch of the BV100, nuclear battery technology has advanced significantly, catapulting China into the forefront of sustainable energy solutions. Its uses go beyond everyday life to include military and harsh environmental contexts. The BV100 opens doors for a variety of applications as China keeps innovating in the field of energy storage, portending a time when nuclear-powered batteries will be crucial in determining the future of the energy system.
