How hemoglobin is breaking battery records — Nature solved platinum’s $2 trillion problem

What if the secret to next-generation batteries lies in human blood, and the blueprint for powering AR contact lenses is found in the Amazon? While humans have built batteries for hundreds of years, nature has been perfecting energy systems for billions. A breakthrough is occurring with the use of hemoglobin—responsible for the red color of blood—to create a catalyst that could replace expensive platinum in advanced batteries. When combined with a specific electrolyte, this blood-inspired technology has set new voltage records, opening up the possibility of affordable, powerful batteries for applications ranging from electric vehicles to the power grid.
