摘要： PROBLEM TO BE SOLVED: To provide a positive electrode for producing a nonaqueous electrolyte battery with a high discharge capacity and excellent cycle characteristics. SOLUTION: The positive electrode includes highly crystalline positive electrode active material particles and a matrix containing a low crystalline positive electrode active material filling gaps among the positive electrode active material particles. By using such a positive electrode for the nonaqueous electrolyte battery, the highly crystalline positive electrode active material particles can secure a sufficient discharge capacity. The positive electrode includes the highly crystalline positive electrode active material particles and the low crystalline matrix. A heterogeneous crystal structure of the positive electrode improves the cycle characteristics of the nonaqueous electrolyte battery. If the crystal structure of the positive electrode is heterogeneous, part of Li ions from the highly crystalline positive electrode active material particles disperses into a defective portion of the matrix, thereby a concentration difference of the Li ions in a thickness direction of a positive electrode active material layer during charge and discharge can be properly reduced within a range not lowering the discharge capacity.
