A team of Chinese researchers revealed the development of an innovative water battery, characterized by its superior ability to continue working for a period of up to 300 years, with the possibility of disposing of it in the environment in complete safety and without the risks of explosion associated with traditional batteries.
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.
