  • "In addition, the organic electrolyte used in a [Li]-ion battery accounts for over 20% of the total cost, whereas the water in the Li-I 2 battery is almost free. The assembly process for solid-state Li-ion batteries is also more expensive than that for the aqueous Li-I 2 battery, and because the iodine is easily recycled we can save the cost of environmental penalties," they added.

    Although the RIKEN team has demonstrated that aqueous Li-I 2 batteries offer significant advantages over conventional Li-ion technology, Yu and Byon do not believe that the aqueous chemistry will take market share away from the Li-ion battery industry.

    "Many batteries, such as Li-ion, lead-acid, nickel metal hydride (Ni-MH) and sodium sulphur (Na-S) batteries, have been used for different markets because of their unique chemistries and characteristics. We expect that Li-I 2 batteries with an aqueous electrolyte reservoir can be applied for large-scale grid storage, and, perhaps, for future EVs, if the solid electrolyte separator can be further developed."
