Researchers at Tohoku University have developed a paper-based Magnesium-air battery that is eco-friendly and powerful.
“We thought that,” the authors of the study write, “if a system in which paper absorbs electrolyte by capillary force, like plants suck up water from the ground, could be applied to magnesium–air batteries, the problem of magnesium dissolving in the electrolyte and self-discharging would be solved. “The battery performance depends on the water absorbent paper,” in other words. Paper-based devices reduce the use of metals and plastics, so this magnesium-air battery poses the least threat to the environment.
