Chinese Startup develops nuclear battery for smartphones that will last 50 years without charging
Betavolt, a Chinese startup, claims a groundbreaking achievement with the development of a nuclear battery that can power smartphones for an impressive 50 years without requiring charging. This nuclear battery, deemed the world's first miniaturized atomic energy system, utilizes 63 nuclear isotopes packed into a module smaller than a coin.
The technology involves converting energy released by decaying isotopes into electricity, a concept first explored in the 20th century and now realized by Betavolt. The startup has initiated pilot testing and plans to mass-produce the battery for various applications, including smartphones and drones.
In their press release, Betavolt stated, "Betavolt atomic energy batteries can meet the needs of long-lasting power supply in multiple scenarios, such as aerospace, AI equipment, medical equipment, microprocessors, advanced sensors, small drones, and micro-robots." They believe this innovation will provide China with a competitive advantage in the AI technology era.
The initial nuclear battery by Betavolt delivers 100 microwatts of power with a voltage of 3V, measuring a tiny 15x15x5 cubic millimeters. The company aims to produce a battery with 1 watt of power by 2025. The small size allows for multiple units to be connected, increasing power output, envisioning a future where mobile phones never need charging, and drones can fly indefinitely.
Ensuring safety, Betavolt's design features a layered structure to prevent fire or explosions when subjected to sudden force. The battery can operate in a wide temperature range, from -60 degrees Celsius to 120 degrees Celsius.
To create the battery, Betavolt used nickel-63, a radioactive element, as the energy source, employing diamond semiconductors for energy conversion. The team developed a thin single-crystal diamond semiconductor and placed a nickel-63 sheet between two diamond semiconductor converters. The radioactive source's decay energy is then converted into electrical current.
Addressing radiation concerns, Betavolt assures users of safety, stating no external radiation. It is deemed suitable for use in medical devices inside the human body, such as pacemakers and cochlear implants. After the decay period, the isotopes transform into a stable, non-radioactive isotope of copper, posing no environmental threat.
The BV100 battery by Betavolt is also considered more secure than conventional batteries, not catching fire or exploding when punctured or exposed to high temperatures.
The development of miniaturized nuclear batteries has been a longstanding goal, and Betavolt's breakthrough technology has the potential to revolutionize electronics by eliminating the need for chargers or portable power banks.

Centre spent Rs 76.13 lakh on print media ads for RSS centenary, reveals RTI
New Delhi: The Union Ministry of Culture allegedly spent Rs 76.13 lakh on print advertisements marking the 100-year celebrations of the Rashtriya Swayamsevak Sangh (RSS), according to a Right to Information (RTI) reply.
The information was sought by RTI activist Ajay Basudev Bose, who filed an application seeking details on expenditure incurred by the ministry for advertisements commemorating the RSS centenary.
Bose shared a picture of the reply from the ministry on his official ‘X’ handle.
“It is informed that an amount of Rs 76,13,129 has been spent on advertisement given in various print media by the Ministry of Culture on the occasion of the completion of 100 years of RSS,” the government’s reply stated.

Bose questioned the expenditure in the post X, “when Everyone knows RSS is Not Registered & Does not Pay any Tax is it justified to spend Tax Payers Money on such Private event??”
Reacting to the development, Karnataka’s IT-BT and Panchayat Raj Minister Priyank Kharge also criticised the spending.
In a post on X, he asked why public money was being used for what he described as a “private ideological project.”
"Modi Sarkar spent Rs 76,13,129 of public money on newspaper advertisements to celebrate 100 years of the RSS. Why is Government spending taxpayers money on an unregistered, non-tax-paying organisation to celebrate their centenary?," he added.
Why is public money being used to serve a private ideological project?

According to reports, the RSS describes itself as a volunteer-based organisation and has stated that it functions as a body of individuals rather than a registered entity.
Founded by Keshav Baliram Hedgewar in 1925, the organisation is marking its centenary year beginning from Vijaydashami in 2025, with the milestone observed on October 2.
