QAZAQ GREEN.  Texas A&M University researchers have developed a biodegradable battery made from natural materials that could replace conventional lithium-ion batteries. The findings were published in the Proceedings of the National Academy of Sciences.

The new battery uses riboflavin (vitamin B2) and L-glutamic acid, both found in the human body, as its key components. Researchers say the material is redox-active, allowing it to store and release energy, while also breaking down safely in water or with enzymes.

Unlike conventional lithium-ion batteries that rely on metals and petrochemicals, the biodegradable battery is derived entirely from renewable biological sources. Lab tests confirmed that the material functions as an anode and is non-toxic to fibroblast cells, raising prospects for its use in implantable and wearable devices.

The project was led by Distinguished Professor of Chemistry Karen Wooley and Professor of Chemical Engineering Jodie Lutkenhaus. The team highlighted the design’s role in promoting a circular economy by ensuring materials can be reused, recycled, or safely returned to nature.

Researchers note that although the battery’s electrochemical performance is comparable to synthetic polymer-based systems, commercialisation will require reducing production costs. Development of viable processes is expected to take 5–10 years.

The research was supported by the National Science Foundation and the Welch Foundation.
