"Blood battery" first appeared, creating a global earthquake because...

Scientists at the University of Cordoba (Spain) have developed a new type of battery that incorporates hemoglobin - the main component of red blood cells - into a zinc-air battery. (Photo: Tien Phong)

Zinc-air batteries are a sustainable alternative to lithium-ion batteries, working through an oxygen reduction reaction, turning oxygen into water and releasing energy. (Photo: inspiringclick)

Hemoglobin was chosen as the catalyst because it has the ability to absorb oxygen quickly and produce water easily, meeting the requirements of the oxygen reduction reaction. (Photo: inspiringclick)

With just 0.165 milligrams of hemoglobin, the " blood battery " can operate continuously for 20-30 days, suitable for implantable devices in the body such as pacemakers. (Photo: Futura Sciences)

The battery operates at a pH of 7.4, similar to the pH of blood, making it compatible with biological environments. (Photo: QS Study)

The current downside of the battery is that it cannot be recharged, so the team is looking for another protein to regenerate oxygen from water and create a closed reaction cycle. (Photo: Tech Briefs)

This battery is not suitable for space applications due to limitations in its rechargeable capabilities. (Photo: QS Study)

This research opens up a new direction in the development of sustainable batteries , contributing to solving the challenge of energy storage in the future. (Photo: Universidad de Córdoba)
