Positive electrode material, positive electrode, and battery

A positive electrode material comprising:

• a positive electrode active material;
• a coating layer containing a first solid electrolyte and coating at least a portion of a surface of the positive electrode active material;
• and
• a second solid electrolyte, wherein
• the first solid electrolyte contains Li, Ti, M, and X, where M is at least one selected from the group consisting of metalloid elements and metal elements other than Li or Ti, and X is at least one selected from the group consisting of F, Cl, Br, and I,
• the second solid electrolyte is in indirect contact with the positive electrode active material with the coating layer disposed between the second solid electrolyte and the positive electrode active material, and
• a ratio of a volume of the first solid electrolyte to a total volume of the first solid electrolyte and the second solid electrolyte is greater than or equal to 4% and less than or equal to 45%.
