  • Materials prepared by metal extraction
    Patent number: 8795887
    Abstract: A method for extracting ions from an active material for use in a battery electrode includes mixing the active material and an activating compound to form a mixture. The mixture is annealed such that an amount of ions is extracted from the active material, an amount of oxygen is liberated from the active material, and an activated active material is formed. Embodiments of the invention include the activated active material, the electrode, and the primary and secondary batteries formed from such activated active materials.
