<jats:p>This paper presents recent progress in Li-ion batteries with the active sub-micron sized particles of the positive electrode chosen in the family of lamellar compounds Li<jats:italic>M</jats:italic>O<jats:sub>2</jats:sub> where <jats:italic>M</jats:italic> stands for a mixture of Ni, Mn elements, and in the family of <jats:italic>y</jats:italic>Li<jats:sub>2</jats:sub>MnO<jats:sub>3</jats:sub>•(1-<jats:italic>y</jats:italic>)LiNi<jats:sub>½</jats:sub>Mn<jats:sub>½</jats:sub>O<jats:sub>2 </jats:sub>layered-layered integrated materials. The structural, physical and chemical properties of these cathode elements are reported and discussed as a function of all the synthesis parameters that include the choice of the precursors and of the chelating agent, and as a function of the relative concentrations of the <jats:italic>M</jats:italic> elements and composition <jats:italic>y</jats:italic>. Their electrochemical properties are also reported and discussed, to determine the optimum compositions in order to obtain the best electrochemical performance while maintaining the structural integrity of the electrode lattice during cycling. </jats:p>
