Abstract

Processes are described for the direct or indirect electrochemical alkaliation of an alkali metal deficient electrochemically active material. The processes include an electrolysis step either during the alkaliation of the alkali metal deficient electrochemically active material on an electrode current collector (direct) or during the regeneration of a reducing agent used for the alkaliation of the electrochemically active material (indirect).
