Atomic Batteries:
An atomic battery, also known as a nuclear battery or radioisotope generator, taps into the energy released from the decay of radioactive isotopes to generate electricity. The terms nuclear battery, atomic battery, and radioisotope generator are often used interchangeably, highlighting the common theme of utilizing radioactive decay for power.
Nuclear Battery of China (Betavolt’s Innovative Technology):
Betavolt, a Chinese startup, is disrupting the field with a unique approach. Unlike traditional thermonuclear batteries, Betavolt’s technology harnesses the semiconductor transition of beta particles from the radioactive source nickel-63. The groundbreaking aspect lies in their ultra-thin single-crystal diamond semiconductor, known as an ultra-wide band gap (UWBG) semiconductor, measuring just 10µ thick.
This innovation involves placing a 2µ thick nickel-63 sheet between two diamond semiconductor converters. Through this setup, the decay energy transforms into an electrical current, forming an independent unit. The modularity of these nuclear batteries allows them to be combined in series or parallel, facilitating the creation of products with diverse sizes and capacities. Betavolt’s approach marks a significant departure from conventional methods, opening up new possibilities in energy technology.
The BV100 Breakthrough:
Betavolt claims a groundbreaking achievement with the BV100, a miniaturized “atomic energy battery” about the size of a coin. This battery, powered by nickel-63, boasts an impressive 50-year lifespan without recharging. Betavolt converts the decay energy into electricity by utilizing diamond semiconductors, marking a significant leap in battery technology.
Zhang Wei, Betavolt’s chairman and CEO, stated that the BV100 is set to be the world’s first mass-produced nuclear battery. The company aims to release a 1-watt power battery in 2025, potentially revolutionizing how we power devices.
The Beta Volt BV100 Battery:
- Size: 15 x 15 x 5 mm
- Power rating: 100 mW at 3V
- Production: 8.64 J per day and 3153 J per year
- Temperature range: -60°C to 120°C
- Safety: Fireproof, explosion-proof, and does not catch fire or explode when punctured or exposed to high temperatures.
Betavolt plans to release a larger 1 W model of the BV100 in 2025 that may be more suitable for phones and drones.
Beta Volt Battery Density:
Betavoltaic batteries typically have a power density of nano to micro-watts per cubic centimeter. For example, one betavoltaic device has a power density of 10 micro-watts per cubic centimeter and a power output of about 1 micro-watt.
Betavoltaic batteries have an energy density that’s 102 to 104 times higher than chemical or fossil fuels. They have a long lifetime potential of several tens to hundreds of years. However, conversion efficiencies have been historically low (<3%).
How A Betavoltaic Device Works:
- The betavoltaic device stores energy in a beta-emitting radioisotope.
- The beta particles interact with a semiconductor p–n junction, creating electron-hole pairs.
- The built-in potential of the p-n junction accelerates the electrons and ions to their respective collectors.
Betavoltaic devices use a non-thermal conversion process. Unlike most nuclear power sources, they don’t use nuclear radiation to generate heat, which is then used to generate electricity.
Betavoltaic devices have high power density, meaning they can release a large amount of power quickly when needed.

FAQs on Nuclear Battery of China:
1. What is the life of a betavoltaic battery?
The lifespan of a betavoltaic battery depends on the specific isotope used and the amount present. However, they generally boast significantly longer lifespans than traditional batteries:
a) Tritium batteries: These are common and offer lifespans of 20 years or more. Their power output gradually decreases over time due to the tritium’s natural decay (half-life of 12.32 years).
b) Nickel-63 batteries: A recent breakthrough in January 2024 revealed a miniaturized nickel-63 betavoltaic device claiming a lifespan of 50 years with its current power output. This technology is still under development but shows potential for even longer durations.
c) Plutonium batteries are less common due to safety and regulatory concerns. Their lifespans can reach centuries due to plutonium’s extremely long half-life (e.g., plutonium-238 has a half-life of 87 years).
2. How long does a tritium battery last?
As mentioned above, tritium batteries typically last 20 years or more with declining power output over time. The specific lifespan depends on the amount of tritium used and the device’s power demands.
3. What is the life of a plutonium battery?
Plutonium batteries can last for centuries due to the long half-life of plutonium isotopes. However, their use is limited due to safety concerns and stricter regulations surrounding radioactive materials.
4. Can beta radiation generate electricity?
Yes, beta radiation can generate electricity through the betavoltaic effect. In betavoltaic batteries, beta particles emitted by the radioactive isotope inside collide with a semiconductor material, dislodging electrons and creating a current. This current can then be used to power small devices.
