[SMM Magnesium Express] Researchers at Japan's University of Tsukuba have developed an all-solid-state magnesium-air rechargeable battery featuring a nitrogen-doped porous graphene cathode. This design replaces platinum-based cathodes and uses a magnesium chloride-based solid polymer electrolyte, successfully addressing chloride-induced degradation that previously limited this technology. The battery maintains performance even when bent to 120 degrees, offering high energy density with enhanced safety, opening new pathways for magnesium in next-generation, low-cost energy storage systems.
