摘要： A composite electrode material consisting of a carbon coated complex oxide, fibrous carbon and a binder. Said material is prepared by a method which includes co-grinding an active electrode material and fibrous carbon, and adding a binder to the co-grinded mixture to lower the viscosity of the mixture. The fibrous carbon is preferably vapor grown carbon fibers.

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： All-solid-state lithium-sulfur electrochemical cells and production methods thereof are described. The Li—S electrochemical cells comprise at least one multilayer component which comprises an ion-conductive solid electrolyte film, a positive electrode film containing a sulfur composite, and a negative electrode film containing lithium. Positive electrodes films, prefabricated electrolyte-positive electrode elements, their uses as well as methods of their production are also described.
