In an innovative leap, Chinese startup Betavolt has introduced a pioneering nuclear battery, approximately the size of a coin, capable of delivering uninterrupted electricity for an astounding 50 years without requiring recharging. As Betavolt transitions from development to the pilot phase, the Beijing-based firm is setting the stage for mass production and a formidable market debut.
Betavolt claims to have achieved a world-first in atomic energy by successfully miniaturizing nuclear power into a module smaller than a coin, incorporating 63 nuclear isotopes. This technological feat leverages a process pioneered in the 20th century, which converts energy released from isotope decay into electricity, thereby achieving miniaturization, modularization, and cost-effectiveness in atomic energy batteries.
Nuclear Battery Technology
Zhang Wei, Chairman and CEO of Betavolt, announced that the BV100 model is the world’s first mass-produced nuclear battery. This device offers 100 microwatts of power and 3 volts of output, all within a compact form factor of 15 x 15 x 5 cubic millimeters. It delivers a daily energy output of 8.64 joules and an annual output of 3,153 joules, boasting an energy density over ten times greater than that of ternary lithium batteries and capable of storing 3,300 megawatts per gram without the hazards of fire or explosion.
Remarkably, these batteries maintain stable power generation across extreme environmental conditions and fluctuating loads, performing consistently between temperatures of 120 degrees and -60 degrees. They are also deemed safe for incorporation into medical devices implanted in the human body, such as pacemakers and cochlear implants, emitting no external radiation.
Future Applications & Global Impact
The potential applications for these batteries are extensive, supporting both parallel and series configurations to suit a variety of uses. Looking ahead, Betavolt plans to introduce a 1-watt battery by 2025, envisioning a future where, regulatory conditions permitting, these atomic batteries could perpetually power mobile phones, transform drones’ operational capacities, and more.
This breakthrough not only places China at the vanguard of advancements in atomic energy batteries and fourth-generation diamond semiconductors but also establishes Betavolt’s leadership in power solutions for aerospace, AI, medical devices, MEMS systems, advanced sensors, small drones, and micro-robots. This achievement significantly outpaces similar efforts by European and American scientific and industrial entities, signaling a new era in energy innovation.
