M.R. Srinivasan, a towering figure in India’s nuclear science community and the former Chairman of the Atomic Energy Commission (AEC), passed away in Udhagamandalam on Tuesday, May 20, 2025, at the age of 95.

Srinivasan's career in the Department of Atomic Energy (DAE) began in September 1955, marking the beginning of a lifelong commitment to India’s nuclear ambitions. He worked closely with the legendary Dr. Homi Bhabha in the groundbreaking effort to establish India's first nuclear research reactor, Apsara. Apsara achieved criticality in August 1956, a major milestone in India’s nuclear journey. Srinivasan’s contributions to the reactor’s construction laid the foundation for India’s rise as a key player in nuclear technology.

Throughout his career, Srinivasan was instrumental in advancing India's atomic energy sector. As the Secretary of the Department of Atomic Energy and later as the Chairman of the Atomic Energy Commission, he played a pivotal role in shaping the nation's nuclear policy and infrastructure. His leadership left an indelible mark on India’s scientific and technological landscape.

In a groundbreaking move, Chinese startup Betavolt claims to have achieved the unimaginable - a nuclear battery that could potentially power smartphones for an astounding 50 years without needing a single charge. This technological marvel introduces a new era of energy storage, paving the way for devices that run continuously, without the need for constant charging.

Revolutionizing Power Storage

Betavolt's nuclear battery, described as the next-generation power solution, is a result of miniaturizing atomic energy. The company managed to place 63 nuclear isotopes into a module smaller than a coin, demonstrating a significant leap in energy storage technology. This innovation promises not just long-lasting power for smartphones but envisions applications in aerospace, AI equipment, medical devices, microprocessors, small drones, and micro-robots.

The Science Behind the Breakthrough

The battery operates by converting the energy released from decaying isotopes, using nickel-63 as the radioactive energy source and diamond semiconductors as energy converters. Betavolt's unique approach involves a single-crystal diamond semiconductor and a thin nickel-63 sheet, resulting in a compact design that delivers 100 microwatts of power and 3V voltage. The layered design ensures safety, eliminating the risk of explosions or fires, even when subjected to punctures or high temperatures.

Safety and Environmental Considerations

Addressing concerns about radiation, Betavolt assures the safety of its nuclear battery, emphasizing its suitability for medical devices like pacemakers. After the decay period, the isotopes transform into a stable, non-radioactive isotope of copper, posing no environmental threat. This innovation, according to Betavolt, is both environmentally friendly and safe.

The Future Implications

This revolutionary nuclear battery technology has the potential to transform various industries, from electronics to automotive technology and AI systems. The modular design allows multiple atomic batteries to be connected, providing higher energy output for diverse applications. This advancement aligns with China's 14th Five-Year Plan, aiming to strengthen the country's economy through technological innovation.
