Cow blood protein powers a revolutionary long-life battery breakthrough

Scientists have developed a groundbreaking battery technology using a byproduct of cattle farming. The system combines a supercapacitor with a traditional battery, achieving rapid charging and an exceptionally long lifespan. Its design relies on abundant metals, avoiding scarce materials like lithium or cobalt.

The new battery uses bovine serum albumin (BSA), a protein found in cow blood, as a biological framework. Researchers repurpose this farming byproduct to create a carbon aerogel embedded with tiny iron nanoclusters. This structure boosts efficiency and allows the battery to charge or discharge in seconds.

Testing shows the iron nanoclusters outperform established materials such as ruthenium oxide. The hybrid system delivers a specific power of 18 kilowatts per kilogram. It also maintains stability over 12,000 cycles, with theoretical potential for 30,000, suggesting a lifespan of decades.

Unlike many modern batteries, this design avoids critical raw materials. Instead, it uses iron and nickel—two of Earth's most common metals. While the technology excels in stationary storage, such as for solar or wind farms, it remains less suited for mobile applications.

As of March 2026, the BSA-based battery is still in early development (TRL 3-4). Research teams at the University of Electronic Science and Technology of China and Tsinghua University continue refining the design. However, no companies have yet begun commercial production.

The battery's rapid charging, long lifespan, and reliance on abundant materials mark a significant advance. Its stability and use of iron and nickel could reduce dependence on scarce resources. For now, the technology remains confined to lab testing, with no immediate plans for market release.
