Researchers in Japan Create a Groundbreaking Battery from Depleted Uranium

Innovative scientists at the Japan Atomic Energy Agency have pioneered a new method of harnessing depleted uranium, which is a byproduct of nuclear power generation, for rechargeable batteries. These batteries are designed to be recharged using renewable energy sources like wind and solar power.

The potential of this technology could change how we utilize nuclear waste, turning an issue into a sustainable resource. While it won’t allow for alternative fuels from items such as drink cans and banana peels just yet, it represents a significant advancement in energy storage solutions.

Currently, Japan has approximately 16,000 tonnes of depleted uranium, while the United States holds around 750,000 tonnes. Globally, the total is estimated to be about 1.2 million tonnes. Researchers indicate that the new battery could effectively charge and deplete with minimal capacity loss over repeated cycles.

In initial tests, the team successfully demonstrated that their battery was capable of powering an LED, exemplifying its effectiveness. Additionally, the batteries featured a unique color-changing capability to indicate their charge state—a neat and practical feature that could enhance user experience.

Looking ahead, researchers aspire to scale this technology significantly and have plans for a large battery prototype that could supply power to approximately 3,000 households in Japan with a capacity of 30,000 kilowatt-hours, tapping into the potential of abundant uranium resources safely.
