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.

UP shocker: Mother hires hitman to kill teen daughter but ends up dead
Agra: In a shocking incident from Uttar Pradesh, a 35-year-old woman hired a hitman for ₹50,000 to kill her teenage daughter but ended up being murdered herself. The body of the woman, identified as Alka, was discovered in a field near the Jasrathpur police station in Etah district on October 6.
According to reports, Alka was reportedly "fed up with the teen's behaviour" and engaged a 38-year-old man, Subhash Singh, for the job, unaware that he was actually her daughter’s lover. The Times of India reported that Alka's daughter had eloped with a young man from their area a few months prior, after which Alka sent her to her maternal home in Farrukhabad.
While staying there, the daughter developed a relationship with Subhash, communicating with him for long hours over the phone. Concerned about the calls, her uncle urged Alka to bring her daughter back home. This situation aggravated Alka, leading her to make the fateful decision to have her daughter killed.
On September 27, Alka contacted Subhash and allegedly offered him ₹50,000 to carry out the murder. In a twist of fate, Subhash informed Alka's daughter of the plan. In exchange for killing her mother, the teenager promised to marry him.
During police interrogations, both Subhash and Alka's daughter confessed to their roles in the crime. They were arrested on Wednesday night, and the investigation is ongoing.
