摘要： A method for preparing a multilayer material based on active lithium, by depositing a film of active lithium on a protective layer at a sufficient speed so that substantially no oxidation of the lithium occurs, and/or during a sufficient time for the adhesion of the lithium to develop after contact with the protective layer. The multilayer material, when incorporated in an electrochemical battery as an anode, has excellent impedance stability and no formation of dendrites during the cycling. Batteries where the anode is the multilayer material are particularly efficient in terms of their coulombic efficiency.

摘要： A positive electrode material is used to produce a positive electrode of a lithium secondary battery, the positive electrode material being a composite lithium material that includes a first lithium compound and a second lithium compound. For instance, the first lithium compound is in the form of particles and comprises at least one compound selected from a layered lithium compound and a spinel-type lithium compound. Preferably, the second lithium compound comprises at least one compound selected from a lithium-containing phosphate compound and a lithium-containing silicate compound. An amorphous carbon material layer and/or graphene-structured carbon material layer is present on the entire surface of the first lithium compound and the second lithium compound. The second lithium compound forms a thin-film layer on part or the entirety of the carbon material layer present on the surface of the first lithium compound particles.
