Abstract (en)
[origin: WO2021092692A1] Methods are described for the direct or indirect electrochemical alkalization of an alkali metal-deficient electrochemically active material. The methods involve an electrolysis step during the alkalization of the alkali metal-deficient electrochemically active material on an electrode current collector (direct alkalization) or during the regeneration of a reducing agent used for the alkalization of the electrochemically active material (indirect alkalization).
