AZUL Energy and Tohoku University Develop Eco-Friendly Battery Using Magnesium and Paper

In a pioneering collaboration, AZUL Energy Inc. and Tohoku University have developed a new type of environmentally friendly battery termed “Metal-Air Paper Battery.” Utilizing safe AZUL catalysts along with common magnesium and paper, this battery was featured in the online early access edition of the Royal Society of Chemistry, RSC Applied Interfaces, on March 18th, and was also chosen for the journal’s outside cover. Triggered by saltwater, the battery generates a voltage of 8 volts and a power output exceeding 100mW/cm². Demonstrations have shown its potential to power wearable devices like SpO2 oxygen saturation monitors and GPS sensors, with promising applications for various other wearable and emergency power supplies.
