This is a sustainable energy storage project from renewable energy sources (solar and wind) for remote electrification, environmentally friendly electric vehicles and widespread portable electronics. Our innovation is an electrochemical method that employs lithium insertion battery type electrodes in a two-step selective process that applies an electrical current through a lithium selective electrode and a chloride selective electrode immersed in natural brine from salt flats:. Lithium chloride is then released by reversing the electrical polarity with the electrodes immersed in a recovery electrolyte.
