  • Mixed metal olivine electrode materials for lithium ion batteries
    Patent number: 8541136
    Abstract: A positive electrode material is provided including an electroactive material having one or more phases comprising lithium (Li), an electroactive metal (M), and phosphate (PO4), wherein in the fully lithiated state, the overall composition has a ratio of Li:M ranging from greater than about 1.0 to about 1.3, a ratio of (PO4):M ranging from about 1.0 to about 1.132, M is one or more metals selected from the group consisting of Cr, Mn, Fe, Co, and Ni, and at least one phase includes an olivine lithium electroactive metal phosphate. In some instances, a composite cathode material including an electroactive olivine transition metal phosphate and a lithium and phosphate rich secondary phase is disclosed for use in a lithium ion battery.
    Type: Grant
