The world is witnessing a paradigm shift in battery technology. China is making headlines through its latest breakthrough in nuclear-powered batteries. Betavolt Technology’s BV100, a nuclear battery can last more than 50 years without recharging. The BV100 is 15 x 15 x 5 millimeters– smaller than a coin– yet it’s designed to power devices for decades. It has sparked global discussions about the future of energy storage. While China is pioneering this technology, the big question remains: Can India harness the potential of nuclear batteries to power its future?

The Science Behind Nuclear Batteries
The conventional lithium-ion batteries rely on chemical reactions. However, the nuclear batteries generate electricity through radioactive decay. The BV100, for instance, utilizes nickel-63 (Ni-63), a radioactive isotope with a half-life of 100.1 years. The Ni-63 isotope decays to Copper-63 by emitting a beta particle and an anti-neutrino. The low-energy beta particles, are then converted into electrical energy through betavoltaic conversion. The betavoltaic conversion is a process that uses the energy from radioactive beta decay to generate electricity. It involves coupling a beta source to a semiconductor junction. This method ensures a continuous power supply for decades, making nuclear batteries an attractive solution for applications where long life and reliability are critical parameters.
How is Nickel-63 Produced?
Nickel-63 is not naturally abundant and hence must be artificially produced. The primary method involves irradiating stable Nickel-62 (Ni-62) in a nuclear reactor. During this process, Ni-62 captures neutrons, leading to the formation of Ni-63. After irradiation, the newly formed Ni-63 is chemically separated and purified for various applications, including nuclear batteries. This production method requires high neutron flux reactors, making it a costly and time-intensive process.
Global Applications from Space to Everyday Tech
The implications of nuclear batteries are far-reaching, spanning multiple industries. In space exploration, these batteries can serve as an ideal power source for deep-space probes, satellites, and lunar habitats, where solar energy is often unreliable. In the defense sector, nuclear-powered drones and surveillance equipment could operate indefinitely, providing strategic advantages for military operations. Medical advancements could also benefit, with pacemakers and other life-saving implants functioning for decades without requiring battery replacements.
While nuclear batteries are still in the early stages of commercialization, the potential for self-powered IoT devices, smart city infrastructure, and even consumer electronics is immense. Imagine smartphones that never need charging or electric vehicles that can run for decades without battery swaps. The possibilities are truly revolutionary.
India’s Role in the Nuclear Battery Revolution
India has long been a proponent of nuclear energy, with institutions like BARC (Bhabha Atomic Research Centre) and IGCAR (Indira Gandhi Centre for Atomic Research) driving nuclear research. With its vast thorium reserves and growing expertise in radioisotope production, India is well-positioned to develop its own nuclear battery technology.
However, to really become a leader in nuclear innovation, nuclear physics education in Indian universities needs to be strengthened with hands on training. More investment in basic teaching and advanced research programs, dedicated nuclear technology courses, and industry-academic collaborations will ensure that India produces the skilled workforce necessary for developing and commercializing nuclear batteries.
1. Strengthening Space Exploration
India’s achievements in space technology, including Chandrayaan, Mangalyaan, and the upcoming Gaganyaan mission, highlight the need for reliable, long-term energy sources. Nuclear batteries could be game-changers, powering lunar land rovers, deep-space missions, and satellite systems without the limitations of solar panels or chemical batteries.
2. Enhancing National Security and Defense
With an extensive border and maritime surveillance requirement, India could benefit from nuclear-powered drones, submarines, and remote sensors. These can operate indefinitely without the need for refueling. This will definitely enhance strategic defense capabilities in high-altitude and remote terrains.
3. Revolutionizing Healthcare
In a country where access to consistent power is a challenge in many rural and remote areas, nuclear batteries could support medical implants, remote health monitoring devices, and life-saving diagnostic equipment without requiring constant battery replacements. This would significantly improve healthcare accessibility and patient safety.
4. Smart Cities and IoT Infrastructure
India’s ambitious Smart Cities Mission relies heavily on an interconnected network of sensors, cameras, and automated systems. Nuclear batteries could ensure long-term, maintenance-free power supply to IoT devices, traffic management systems, and pollution-monitoring stations in metropolitan areas like Delhi, Mumbai, Bangalore, and Kolkata.
Challenges and the Road Ahead
Despite their promise, nuclear batteries definitely face certain challenges. The first and foremost is public perception and the safety concerns. While these batteries are designed to be safe and non-hazardous, public perception regarding anything labeled “nuclear” remains a major hurdle. India would need to educate the masses and implement stringent safety and regulatory frameworks to ensure the public trust in the technology.
Another challenge is resource availability and production. While India has abundant thorium reserves, it would need to invest in nickel-63 production facilities or seek international collaborations to secure the required isotopes for nuclear batteries. Further, large-scale commercialization will require government and private sector partnerships to strengthen the research, development, and implementation.
India’s Nuclear Energy Future requires Seizing the Opportunity
China’s strides in nuclear battery technology serve as a wake-up call for India. The country has one of the best the scientific expertise, and nuclear infrastructure. It also has a great research potential to develop its own nuclear-powered energy solutions. As part of the Atmanirbhar Bharat (Self-Reliant India) vision for 2047, India must take decisive steps in advancing nuclear battery technology. This is not only a matter of energy independence but also an opportunity to dominate the global market in advanced nuclear technology.
To be a leader in this field, India must invest in betavoltaic research, and strengthen nuclear physics education. We need to strengthen domestic isotope production capabilities. Encouraging private-public partnerships in nuclear technology will be an added bonus. By doing so, India can emerge as a leader in next-generation nuclear battery solutions. This will ensure a sustainable and technologically advanced future.
The transition to nuclear batteries could eliminate charging stations, reduce battery waste, and create a self-sufficient energy ecosystem. The question now is not if India will embrace nuclear batteries, but how soon it will take the lead on the global stage.
