The evolution of the layered and spinel oxides as high-voltage cathodes for a rechargeable Li-ion battery will be chronicled, and the limitations of the organic-liquid electrolytes will be contrasted with the Braga Li<sup>+</sup> glass electrolyte from which a metallic lithium anode can be plated reversibly dendrite-free. The performance of a safe high-voltage cell with a Mn-Ni oxide as cathode will be presented.
