Abstract
An electrode comprises a sulfide-based solid electrolyte, an electrolyte microparticle, and a composite particle. The sulfide-based solid electrolyte includes S and P, has a PScrystalline phase, and has a molar ratio of the PScrystalline phase to a total amount of phases consisting of P and S of 60% or more. A ratio of a D50 of the electrolyte microparticle to a D50 of the sulfide-based solid electrolyte is 0.5 or less. The composite particle comprises a positive electrode active material particle and a coating film. The coating film includes a phosphorus compound. The phosphorus compound includes at least one of a first element (a glass network forming element) and a second element (a transition element) as well as phosphorus. In the coating film, a relationship of 'expression (1): C(C+C+C)≤2.5' is satisfied. C, C, C, and Crepresent element concentrations of respective elements measured by XPS.
