Original Abstract Submitted
A composite positive electrode active material includes a positive electrode active material and a coating layer coating at least a portion of a surface of the positive electrode active material. The coating layer contains a first coating material and a second coating material. The first coating material is a fluoride solid electrolyte, and the second coating material is a material that reacts with at least one selected from the group consisting of water and hydrogen fluoride, to form at least one selected from the group consisting of lithium oxide and lithium fluoride.
