The global demand for advanced battery technology, capable of enduring extended periods while fitting into various devices, has been a persistent challenge. Numerous contenders, from lithium-ion to graphene and solid-state batteries, have entered the race. However, a recent revelation from the Chinese company Betol has turned heads. They announced the development of a nuclear battery with a staggering lifespan of up to five decades, offering continuous power without the need for recharging or replacement.
Understanding what sets nuclear batteries apart is crucial. Unlike conventional batteries relying on chemical reactions, nuclear batteries utilize the energy released by the breakdown of radioactive elements to generate electricity. Their extended lifespan and ability to function in harsh environments make them suitable for applications such as spacecraft, deep-sea probes, pacemakers, and sensors.
Despite their potential, nuclear batteries have faced limitations, including high costs due to rare materials and safety concerns related to radioactive elements. Betol, a young and ambitious company founded in April 2021, aims to overcome these challenges. They have introduced a modular nuclear battery employing a cutting-edge diamond semiconductor and a radioactive isotope, nickel-63.
The BV 100, Betol’s first product, is a miniature marvel, measuring only 15x15x5 cubic millimeters. Despite its small size, it boasts a power output of 100 microwatts and a voltage of 3 volts, sufficient to power low-energy devices like medical implants, smart sensors, and micro-robots. The BV 100’s remarkable feature lies in its ability to provide a stable and continuous power supply for up to 50 years without maintenance or environmental impact.
Compared to conventional batteries, the BV 100 offers advantages such as a higher energy density, equivalent to storing more energy in a smaller space. With a capacity of 3,300 megawatts per gram, it rivals the power output of three nuclear reactors. The safety aspect is emphasized, with no risk of fire or explosion, making it suitable for various applications requiring high reliability and durability.
Betol envisions a future where nuclear batteries, exemplified by the BV 100, play a pivotal role in diverse fields, including healthcare, communication, security, and transportation. Their ambitious plans include the launch of a 1-watt nuclear battery by 2025, potentially transforming mobile communication and aviation. The company sees limitless possibilities in providing unlimited connectivity and mobility, showcasing China’s prowess in atomic energy batteries and fourth-generation diamond semiconductors.
While nuclear batteries have traditionally been associated with space exploration, Betol’s pilot-stage nuclear battery signifies a shift toward broader applications. The technology’s potential benefits for electric vehicles (EVs) and various industries are evident. As Betol progresses towards mass production, aiming for affordability and accessibility, the world anticipates further advancements and innovations in the realm of compact and enduring nuclear batteries.
