Abstract
Insertion compounds that are not stable in pure water can be prepared by an aqueous electrochemical method. The pH of the electrolyte and/or the concentration of ions of the inserted species must be sufficiently high to provide stability for the product compound. The method is useful for further lithiation of conventional lithium ion battery cathode materials.
