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.

India, Ethiopia elevate ties to strategic partnership as PM Modi holds talks with his counterpart
Addis Ababa (PTI): India and Ethiopia on Tuesday elevated their historical ties to a strategic partnership, as Prime Minister Narendra Modi held wide-ranging talks with his Ethiopian counterpart Abiy Ahmed Ali during which they discussed issues of bilateral and mutual interest.
Modi, who arrived here from Jordan on his maiden bilateral visit, was accorded a ceremonial welcome at the National Palace ahead of the bilateral talks, reflecting the vibrant India-Ethiopia relations rooted in shared history and a promising future.
"We are elevating India and Ethiopia relations to a strategic partnership. This step will provide new energy, new momentum and new depth to our ties," Prime Minister Modi said during the delegation-level talks.
He thanked PM Ali for his support in India's fight against terrorism. "The support of friendly countries in this struggle against terrorism holds great significance," Modi said.
"Today, we got the opportunity to deliberate on the key aspects of our cooperation, such as economy, innovation, technology, defence, health, capacity-building and multilateral cooperation. I am pleased that today, we have decided to double the student scholarship for Ethiopia in India," Modi said.
Modi said that India and Ethiopia have shared contact, dialogue, and exchange for thousands of years. The two countries, which are rich in languages and traditions, are symbols of unity in diversity, he added.
"Both countries are democratic powers committed to peace and the welfare of humanity. We are co-travellers and partners of the Global South. On international platforms, we have stood shoulder-to-shoulder," he said.
The two sides signed eight MoUs/agreements, including upgrading ties to 'Strategic Partnership', customs cooperation, establishing data center at the Ethiopian Foreign Ministry, UN Peacekeeping training cooperation, debt restructuring under G20, more ICCR scholarships and AI short courses for Ethiopians, and support for maternal and neonatal healthcare.
Modi said the African Union's headquarters in Ethiopia makes the country a meeting point of African diplomacy. "Inspired by the common vision of an inclusive world, in 2023, India ensured that the African Union became a G20 member," he said.
In 2023, during India’s G20 Presidency, the African Union was admitted as a permanent member of the G20.
Modi said that though this is his first visit, he felt a deep sense of belonging and warmth, reflecting the thousands of years of connection between the two countries.
On his part, Prime Minister Ali said the two countries share over thousands of years of connection through trade, diplomacy, education, culture and even in our food and traditions. "These ties continue to shape a deep friendship, collaboration and mutual respect between our people," he said.
"We also appreciate your consistent message that Africa's priorities must lead the partnership. These kinds of dignified, respectful messages for Africa are very important. Mr Prime Minister, keep pushing. That is the type of message we are expecting from all our trusted friends," Ali said.
He said this aligned fully with Ethiopia's development plan - African-owned, African-led, and African-defined.
"Today, we meet with a clear focus to shape a modern partnership, grounded in sovereignty, self-reliance and practical cooperation. Our cooperation is rooted in equality and South-South solidarity," he said.
"Our economy is performing strongly. Last year, we grew 9.2% and this year we are expecting 10.3% GDP growth. Besides GDP growth, our FDI inflow is also rising big time. India is the leading source for our FDI," he said.
"We have more than 615 Indian companies which are investing in Ethiopia. This all gives our cooperation a strong foundation of trust. I think our decision today that we elevate our historic relationship to a strategic relationship is the right decision," he added.
Ethiopia also conferred its highest award - The Great Honour Nishan of Ethiopia - on PM Modi. He is the first global head of state to receive this award.
Prime Minister Modi also went to the Friendship Park and Friendship Square in Addis Ababa with PM Ali.
In a warm and special gesture, PM Modi was earlier received by his Ethiopian counterpart at the airport and accorded a warm and colourful welcome.
"Ethiopia is a nation with great history and vibrant culture," Modi said.
PM Ali informed his Indian counterpart about the varieties of Ethiopian coffee during informal talks.
"At Addis Ababa airport, took part in a traditional Coffee Ceremony with Prime Minister Abiy Ahmed Ali. The ceremony beautifully highlights Ethiopia’s rich heritage," Modi said.
In a unique gesture, the Ethiopian Prime Minister drove Modi to the hotel.
On the way, he took a special initiative of taking PM Modi to the Science Museum and Friendship Park, which was not in the itinerary.
"Gratitude to Prime Minister Abiy Ahmed Ali for showing me glimpses of Ethiopian history and culture at the National Palace Museum in Addis Ababa. It was a powerful reminder of Ethiopia’s rich traditions," Modi said in a post on X.
The Nobel Peace Prize-winning Ethiopian PM’s special gestures show remarkable respect for Modi, sources said.
"Thank you Ethiopia for a welcome that was unforgettable. The Indian community showed remarkable warmth and affection. India-Ethiopia friendship is going to get even more robust in the times to come," Modi said.
When Modi arrived at the hotel, he was warmly welcomed by the members of the Indian community. Local artists performed dances. Some of them danced on the theme of the popular Hindi song 'Aisa Des Hai Mera' to welcome him.
On Wednesday, Modi will address the Joint Session of Parliament and share his thoughts on India's journey as the "Mother of Democracy" and the value that the India-Ethiopia partnership can bring to the Global South.
PM Modi arrived in Ethiopia from Jordan, where he held a one-on-one meeting with King Abdullah II at the Husseiniya Palace on Monday before the delegation-level talks.
India and Jordan also inked MoUs in the fields of culture, renewable energy, water management, digital public infrastructure and twinning arrangement between Petra and Ellora, aimed at giving a major boost to bilateral ties and friendship.
From Ethiopia, Modi will visit Oman on the final leg of this three-nation tour.
