Abstract
The invention relates to a lithium battery, comprising at least one lithium intercalation compound, made up of crystallites and obtained by a production method, comprising at least the following steps: formation of a homogeneous mixture of at least one precursor for the lithium intercalation compound with a given adjunct, chemically stable with relation to crystallites and designed to limit the growth of crystallites or crystallite precursors during the formation thereof, thermal treatment of the homogeneous mixture for the synthesis of the lithium intercalation compound in the form of crystallites and to give a composite material comprising at least two phases formed respectively by the lithium intercalation compound and the adjunct and forming of the composite material to give said electrode. The invention further relates to an electrode obtained by said method and lithium battery comprising such an electrode.
