Abstract:
A lithium-ion secondary battery with high capacity is provided. Alternatively, a lithium-ion secondary battery with unproved 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.

Claim (Index 2):
A method for forming an active material, comprising the steps of:\n forming a mixture of a lithium compound, a manganese compound, and a nickel compound; heating the mixture and obtaining a secondary particle composed of sintered primary particles; crushing the secondary particle into a plurality of particles; and coating the plurality of particles with a layer comprising graphene, wherein a first cleavage plane of a first particle in the plurality of particles is covered with the layer comprising graphene.
