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.

Jammu and Kashmir enter maiden Ranji Trophy final; Bengal left stunned
Kalyani (West Bengal) (PTI): Sixty seven years after their maiden appearance, Jammu and Kashmir stormed into the Ranji Trophy finals for the first time on Wednesday, upstaging two-time former champions Bengal by six wickets in the semifinals here to add another historic chapter to a fairytale season so far.
Auqib Nabi's stunning nine-wicket match haul and their IPL star Abdul Samad's fearless strokeplay ensured that the side once labelled "perennial underachievers" now stands one step away from the title.
Chasing a modest 126 at the Bengal Cricket Academy ground, J&K rode on Samad's unbeaten 30 off 27 balls (3x6, 1x4) and rookie Vanshaj Sharma's composed 43 not out off 83 ball (4x4) as the pair stitched an unbroken 55-run stand for the fourth wicket to seal history on the fourth and penultimate day of the semifinal.
In a heartwarming gesture, Samad, who had done the bulk of the damage, allowed the 22-year-old Vanshaj to finish it in style and the youngster launched Mukesh Kumar over long-on for six to spark wild celebrations in the visiting camp.
From strugglers to history-makers
======================
Jammu and Kashmir had played 334 Ranji matches before this season, winning only 45. It took them 44 years to register their first victory, against Services in 1982-83.
Knockout appearances were rare. A breakthrough came in 2013-14 when they edged Goa on net run rate to reach the quarterfinals, and in 2015-16 they stunned Mumbai at the Wankhede Stadium under state icon Parveez Rasool.
But consistency eluded them for decades as this season, under coach Ajay Sharma and captain Paras Dogra, they transformed belief into results.
After an opening loss to Mumbai, they bounced back with innings wins over Rajasthan and key victories against Delhi and Hyderabad to enter the knockouts.
A dramatic 56-run win over Madhya Pradesh in the quarterfinal, powered by Nabi’s 12/110, brought them to the semifinals for the first time.
Bengal's big names, bigger letdown
=======================
With four India internationals in Mohammed Shami, Akash Deep, Mukesh Kumar and Shahbaz Ahmed, and India A star batter Abhimanyu Easwran along with home advantage to boot, this was Bengal's game to lose.
They did exactly that after folding for 99 in 25.1 overs on day three that set Jammu and Kashmir a paltry 126 to win.
Resuming at 43/2 on the penultimate day, J&K lost an early wicket but Bengal failed to sustain pressure despite Akash Deep's relentless 15-over morning spell (3/46) and Shami's probing 1/24 from 24 overs.
There were anxious moments when Shubham Pundir was cleaned up and Dogra edged behind -- a low diving catch by Abishek Porel off Akash Deep eventually upheld after review.
But Bengal looked fatigued and short of ideas once Samad counterattacked. The IPL batter, retained by Lucknow Super Giants, turned the tide in a single over against Akash Deep that fetched 18 runs.
He did not spare Shahbaz either, dancing down the track to deposit him over mid-wicket and then through covers as J&K crossed the 100-run mark.
From there, shoulders dropped in the Bengal camp.
The introduction of part-time options and a visible dip in intensity underlined a campaign that promised much but fizzled when it mattered most.
Nabi's season for the ages
==================
The foundations of Jammu and Kashmir's win, however, were laid by Nabi.
"Last time we missed it in the quarters but we did all the hard work and we deserved it," said Nabi after winning the man-of-the-match.
The 29-year-old pacer followed his 12-wicket match haul in the quarterfinal against Madhya Pradesh with another devastating effort, finishing with nine wickets in the match, including a five-for in the first innings, to take his season's tally to 55 wickets at an average of under 13.
Nabi had also contributed with the bat playing a decisive knock at No.9.
J&K had posted 302 in their first innings, reducing the deficit to 26, thanks to Dogra's gritty 58 (112 balls), Samad's counterattacking 82 (85 balls) and a crucial late surge from Nabi (42 off 54) and Yudhvir Singh (33) in a 64-run last-wicket stand.
Dogra's milestone
===========
For 41-year-old captain Paras Dogra, it was a week of personal and collective milestones.
In a career spanning 24 years across Himachal Pradesh, Pondicherry and now J&K, Dogra also became only the second batter after Wasim Jaffer to score 10,000 Ranji Trophy runs.
Introduced to the game by his father Kultar, Dogra's journey has been one of endurance and quiet steel.
"It's a big achievement, never thought about it. I enjoyed the journey full of ups and downs. The game makes you a strong human being," Dogra said.
His resolute half-century in a 143-run partnership with Samad in the first innings set the tone for the side's resilience.
