Abstract: To provide a fabricating method and a fabricating apparatus for a lithium-ion secondary battery having stable charge characteristics and lifetime characteristics. A positive electrode is subjected to an electrochemical reaction in a large amount of electrolytic solution in advance before a secondary battery is completed. In this manner, the positive electrode can have stability. The use of the positive electrode enables fabrication of a highly reliable secondary battery. Similarly, a negative electrode is subjected to an electrochemical reaction in a large amount of electrolytic solution in advance. The use of the negative electrode enables fabrication of a highly reliable secondary battery.

Abstract: A lithium-ion secondary battery with high capacity is provided. Alternatively, a lithium-ion secondary battery with improved cycle characteristics is provided. To achieve this, an active material including a particle having a cleavage plane and a layer containing carbon covering at least part of the cleavage plane is provided. The particle having the cleavage plane contains lithium, manganese, nickel, and oxygen. The layer containing carbon preferably contains graphene. When a lithium-ion secondary battery is fabricated using an electrode including the particle having the cleavage plane at least part of which is covered with the layer containing carbon as an active material, the discharge capacity can be increased and the cycle characteristics can be improved.
