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.

Vinod Tawde seeks apology from Kharge, Rahul through legal notice, warns of defamation lawsuit
Cash-for-vote row
New Delhi, Nov 22: BJP leader Vinod Tawde has demanded an apology from Congress president Mallikarjun Kharge and the Leader of Opposition in Lok Sabha Rahul Gandhi for making "false and baseless" allegations against him in the cash-for-votes incident in Maharashtra, saying if they don't he would sue them for defamation.
Tawde was accused by Bahujan Vikas Aghadi, a regional party, of distributing Rs 5 crore to woo voters, with its members barging into a hotel room on November 19 in a Mumbai suburb, where the BJP leader was present.
The former Maharashtra minister and BJP national general secretary claimed innocence, saying the alleged amount was not recovered in the probe by the Election Commission and police.
"The Congress only believes in spreading lies, and this incident is a proof of the party's low level politics to dent me and my party's image," Tawde said.
The two Congress leaders and the party spokesperson Supriya Shrinate seized on the row to accuse the BJP of using money power to influence the November 20 assembly polls in the state.
The legal notice sent to the three claimed that they were aware that they were pushing a "totally false story fabricated" by them.
"You all have deliberately, mischievously with the sole intention of damaging the reputation of our client intentionally fabricated the story distribution of money. You all have published false, baseless allegations against our client on various media for tarnishing his image in the eyes of right thinking people in the society," the notice read.
The Congress leaders were in a "great hurry" to damage Tawde's reputation, they did not bother to check the fact and or despite knowing the entire fact they made the false, baseless allegations, it said.
"The entire imputation made by you all are totally false, baseless, malicious and mala fide and as our client is in no way involved in any such illegal activity and as a responsible office bearer of the national political party he is aware of his duties," it added.
The notice demanded an "unconditional apology" to Tawde within 24 hours from the time the receipt of the notice, which was sent on November 21, and published in newspapers and X.
If they do not offer apology, then Tawde will initiate criminal proceedings under Section 356, which covers defamation, of the Bharatiya Nyaya Sanhita and also civil proceedings for the damages of Rs 100 crore against the three Congress leaders, the notice said.
