  • Publication number: 20240332639
    Abstract: An electrode structure for a secondary battery includes an electrode and a composite layer. In a cumulative frequency distribution of inorganic particles having average particle size of 3 ?m or more with respect to a thickness direction of the composite layer, a first region is set to a range 0 or more and less than 25 and the second region is set to a range 25 or more and 100 or less. The first region is 5% or more and 40% or less of the thickness of the composite layer. Average particle size of inorganic particles satisfy a relationship of R1<R2.
