Positive active material and nonaqueous electrolyte secondary battery produced using the same |
摘要 |
A positive active material is composed of particles of a compound oxide of lithium and a transition metal. This compound oxide has a layered structure. A coating layer of an inorganic compound and a carbonaceous material is formed on at least part of each surface of the particles. The inorganic compound is a lithium compound. The weight ratio of the inorganic compound to the carbonaceous material ranges between 99:1 and 60:40. The weight ratio of the particles to the coating layers ranges between 98:2 and 70:30. |
