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.

摘要： A process for purifying raw carbon nanotubes to obtain a content in metallic impurities of between 5 ppm and 200 ppm. The process includes an increase in the bulk density of the raw carbon nanotubes via compacting to produce compacted carbon nanotubes. The process further includes sintering the compacted carbon nanotubes by undergoing thermal treatment under gaseous atmosphere in order to remove at least a portion of the metallic impurities contained in the raw carbon nanotubes, and consequently producing purified carbon nanotubes. These purified carbon nanotubes are directly usable as electronic conductors serving as basis additive to an electrode material without requiring any subsequent purification step. The electrode material can then be used to manufacture an electrode destined to a lithium-ion battery.
