Editor’s Note: The lightest of all metals, lithium is a fundamental material for the production of lithium-ion rechargeable batteries (LIBs) which achieve high energy and power densities thanks to the unique atomic structure and electrochemical properties of lithium. Having been globally commercialized for some three decades, LIBs are available in various types, based on cathode […]
