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.

Belagavi: Miscreants break into house, stab pregnant woman
Belagavi: Miscreants reportedly broke into a house and stabbed a pregnant woman to death using a knife, in Chikkuda village of Athani taluk here on Sunday.
The deceased pregnant woman has been identified as Suvarna Mantaiah Mathapathy (35) of Chikkuda village. Suvarna was a mother of four daughters and was expecting her fifth child. She was due to give birth within the week, with the delivery date already scheduled by her doctor.
The incident reportedly occurred on Saturday when Suvarna's husband went to the plantation to fetch fodder for the cows, and their children were at school. During this time, the attackers broke into the house and struck Suvarna with a sharp weapon, and later fled the scene.
When her husband returned and called for her, Suvarna did not respond. Upon entering the house, he found his pregnant wife lying in a pool of blood. He rushed her to a nearby private hospital, but the doctor confirmed that she had died on the way due to her severe injuries.
The exact reason for the murder is yet to be ascertained. Meanwhile, a case in connection with the incident has been lodged at the Athani Police Station.
