Patent ID: 7909893

Claim:
A method for production of an electrode for a lithium battery including a composite material, the composite material comprising a first phase formed by a lithium intercalation compound made up of crystallites and a second phase constituted by a selected specific additional compound, the method comprising at least the following steps: forming the composite material, wherein forming the composite material comprises: forming a homogeneous mixture of at least one precursor of the lithium intercalation compound with the selected specific additional compound; and synthesizing the lithium intercalation compound by heat treatment of the homogeneous mixture, wherein the selected specific additional compound is different from the precursor and is chemically stable with respect to crystallites and to said precursor under the synthesis conditions of the lithium intercalation compound, to limit the growth of the crystallites, and wherein the selected specific additional compound is selected from the group consisting of oxides, nitrides, carbides, borides and silicides of at least one chemical element selected from manganese, calcium, yttrium, lanthanum, titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, aluminum, cerium, iron, boron and silicon; and shaping of the composite material so as to obtain said electrode.
