  • Method of synthesizing alkaline metal intercalation materials for electrochemical cells
    Patent number: 5531920
    Abstract: A method for preparing an alkaline metal transition metal oxide charge storage material for electrochemical cells. The material may be used in a lithium rechargeable electrochemical cell along with a conventional lithium intercalation electrode. The material may be prepared by providing a transition metal hydroxide and reacting it with a alkaline metal containing oxidizing agent. The ratio of the transition metal to the alkaline metal should be approximately 0.5:1 to 1.2:1.
