The Chinese-based battery manufacturer Betavolt has started the mass production of its nuclear battery, the BV100, which is the size of a coin. This battery promises a 50-year lifespan and can provide continuous energy without the need for recharging.
Nuclear Battery Designed to Last 50 Years
The core of the battery consists of a nickel-63 layer just two microns thick and is positioned between two diamond semiconductor plates. This design allows the 5 mm-sized battery to deliver 100 microwatts of power at 3 volts.
Currently, this battery is not sufficient for high-energy devices such as smartphones or laptops. However, Betavolt has announced that it will release a more powerful version with 1-watt power in 2025. Tests have revealed that Google Chrome shortens iPhone battery life compared to Safari. This result has surprised many.
The highly anticipated new Apple Watch update has officially been released. The version brings with it many important innovations.
The BV100’s most significant feature is that it offers 10 times the energy density of conventional lithium-ion batteries. As a result, it does not self-discharge over time like chemical batteries, nor is it affected by extreme temperature changes.
Operating seamlessly between -60°C and +120°C, the BV100 poses no risk of fire or explosion. Additionally, its environmental impact is minimal; the nickel-63 inside the battery gradually converts into stable copper, avoiding the production of dangerous radioactive waste. This makes it much safer compared to traditional nuclear batteries.
Betavolt’s BV100 and its upcoming more powerful versions are expected to be used in many fields such as drones, artificial intelligence systems, medical devices, micro-robots, and space technologies.
