<p>Composite cathodes (24) are disclosed which include a mixture of a first homogeneous cathode material and a second homegeneous cathode material, and binders as necessary. By choosing particular types and relative amounts of the first and second homogeneous cathode materials, the resulting composite cathodes can have matched formation and reversible cycling capacities (for a given anode material) and sloping discharge profiles. The first and second homogeneous cathode materials used in the composite cathodes disclosed herein may each be one of lithium molybdenum sulfides, lithium molybdenum oxides, lithium vanadium oxides, lithium chromium oxides, lithium titanium oxides, lithium tungsten oxides, lithium cobalt oxides, lithium nickel oxides, and lithium manganese oxides. Lithium ion cells having such composite electrodes are also disclosed herein. Such cells include a cell container (14), a non-aqueous electrolyte (34) and an anode (22) including a mixture of homogeneous graphitic carbon particles and homogeneous non-graphitic carbon particles.</p> |
