Definitions

  • Patent Document 1 when controlling the conductivity of the powder compact as in Patent Document 1, the battery as a whole becomes highly resistant, leading to a decrease in battery performance. Furthermore, Patent Document 1 is a countermeasure specialized for composite oxides containing lithium and nickel as main components, and lacks versatility.
  • One object of the present disclosure is to provide a positive electrode material that can maintain a high resistance even in a heat-generating environment such as a short circuit, regardless of the type and characteristics of the positive electrode active material.
  • the thickness of the positive electrode active material layer is not particularly limited.
  • a plurality of layers having different compositions may form one positive electrode active material layer.
  • two or more layers containing active material particles having different average particle sizes may be laminated, or two or more layers having different types of positive electrode active materials or different compositions of positive electrode active materials may be laminated.
  • Film formation step (S2) A laminate (positive electrode precursor) of the positive electrode current collector and the precursor layer is placed in a predetermined reaction chamber, and the active layer in the precursor layer is coated with a coating containing the second metal oxide by ALD according to the following procedure. A portion of the surface of the material particles was coated.
