British-Nigerian scientists Eseosa Ekanem and Fatimah M. Sanni have made history by helping develop the world’s first-ever carbon-14 diamond battery.
Designed to last up to 5,000 years, this groundbreaking invention could transform energy storage across multiple industries.
The innovation, created by a team from the UK Atomic Energy Authority (UKAEA) and the University of Bristol, encapsulates the radioactive isotope carbon-14 within a synthetic diamond. As the isotope decays, it emits beta radiation, which the diamond absorbs and converts into continuous electrical current—akin to how solar panels convert sunlight into energy.
Transformative Potential Across Industries
The diamond battery’s potential use cases are vast, ranging from powering medical implants like pacemakers to space exploration equipment, where traditional battery replacement is impractical. These batteries could also enhance security devices and power active radio frequency (RF) tags, allowing decades-long device identification and tracking.
Professor Tom Scott of the University of Bristol emphasized the battery’s suitability for extreme environments, stating:
“Our micropower technology can support a range of important applications, from space technologies and security devices to medical implants.”
A Vision for Change
Eseosa Ekanem shared her drive for innovation, stating:
“I want to be a part of something that brings about a change—whether it’s change now or change towards the future.”
This sentiment aligns with the battery’s alignment with the United Nations Sustainable Development Goals (SDGs), including Affordable and Clean Energy (SDG 7), Industry, Innovation, and Infrastructure (SDG 9), and Good Health and Well-being (SDG 3).
Recognition and Future Impact
Sarah Clark, Director of Tritium Fuel Cycle at UKAEA, described the invention as a “safe, sustainable way to provide continuous microwatt levels of power.”
The diamond battery represents a major leap in energy innovation and sustainability, with implications for improving the reliability of life-saving medical devices and supporting advancements in space exploration.
As pioneers in the development of this game-changing technology, Ekanem and Sanni are not only advancing science but also paving the way for future Black women in STEM.
