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 4):
The method for forming the active material according to  claim 2 , wherein the crushing step is performed using a bead mill.
