Abstract
There are provided an electrolyte-positive electrode structure which comprises a thin solid electrolyte and can develop excellent capacity and output, and a lithium ion secondary battery comprising the same. An electrolyte-positive electrode structure 7 comprises: a positive electrode 4 comprising a positive electrode active material layer 3 formed on a current collector 2; and a solid electrolyte 6 containing inorganic particles having lithium ion conductivity, an organic polymer, and a polymer gel, in which the organic polymer binds the inorganic particles and can be impregnated with the polymer gel, and the polymer gel holds an electrolyte solution and is impregnated into the organic polymer, wherein the positive electrode active material layer 3 is integrated with the solid electrolyte 6 using the organic polymer as a medium.
