The new technology relies on a neutral electrolyte and an aqueous solution of magnesium and calcium salts, which enables it to withstand about 120,000 charging and discharging cycles, a number that exceeds the lifespan of current lithium-ion batteries.
The team used organic polymers with a “honeycomb” design to improve the efficiency of the ions and prevent corrosion of the electrodes. Although its energy density is still lower than its counterparts, experts see it as a safe and sustainable alternative to large energy storage systems and renewable energy networks, given that it is free of toxic and flammable materials.
