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.

Mass funeral of four brothers leaves UAE community in mourning after fatal road accident
Report: Thufail Muhammad Abudhabi
Dubai: The funeral of four young brothers who died in a tragic road accident near Abu Dhabi drew hundreds of mourners to the Al Qusais cemetery on Tuesday evening, leaving the UAE’s expatriate community in deep shock and grief.
The children Ashaj (14), Ammar (12), Azaam (8) and Ayyash (5) were the sons of Abdul Latheef and Ruksana, natives of Kerala’s Malappuram district. The family was returning to their Dubai residence after attending the Liwa Festival on the outskirts of Abu Dhabi when their car met with a fatal accident early Sunday morning.
Three of the children died on the spot, while Azaam succumbed to his injuries on Monday evening during treatment. The family’s domestic helper, Bushra Fayaz (49), also lost her life in the crash. Her body was repatriated to India on Monday night, and funeral rites were held in Kerala on Tuesday.
Abdul Latheef, who sustained injuries in the accident, arrived at the cemetery from Abu Dhabi in a wheelchair, his hand in a sling, to attend the burial of his sons. Mourners described the scene as one of the most heartbreaking they had ever witnessed.
“I have never seen the mass burial of children from the same family. It was devastating for everyone present,” said a social worker who assisted the family.
The couple’s only daughter, Izza (10), survived the accident with minor injuries and is undergoing treatment. Unaware of the loss of her brothers, she was seen playing on a mobile phone from her hospital bed.
Relatives said informing the parents about the tragedy was handled with extreme care. Abdul Latheef was told late on Sunday night, while Ruksana who had undergone surgery for an injury to her hand was informed only on Tuesday after counsellors were brought in to break the news professionally.
Before the burial, the parents were allowed to see their children one last time. Ruksana was taken by ambulance to the mortuary, while Abdul Latheef obtained special permission for temporary discharge from hospital to attend the funeral. Ruksana remained hospitalised with her daughter.
Though the family holds Ras Al Khaimah visas, special permission was obtained to conduct the burial in Dubai, where the family resides and where most relatives are based. Community members expressed gratitude to the Dubai authorities for facilitating the process.
Abdul Latheef runs a business in Ras Al Khaimah, while Ruksana works as a property consultant in Dubai. All five children were students of Arab Unity School in Dubai, following the British curriculum. The school management issued a circular to parents outlining measures to support students and families affected by the tragedy and advising on how to discuss the loss sensitively with children.
The cause of the accident has not yet been officially confirmed by Abu Dhabi Police. Public discussions have pointed to possible factors such as dense winter fog and overspeeding, though authorities are yet to release findings.
