"aqueous electrolyte much cheaper, safer... increasing voltage while avoiding potentially dangerous battery-swelling hydrogen build-up... applied organic catechol to electrolyte, changing electron transfer model from normal inner sphere transfer in electrolyte to outer sphere transfer, resulting in water molecules being more stable and hydrogen build-up controlled... 2X energy of lithium, smaller, charges much faster, many times greater recharging cycle life... 2X increased voltage window, 1.5 - 3X better performance"
