| 摘要 |
An object of the present invention is to enhance energy density and output density of an all-solid state ion secondary battery. To achieve the object, the present invention provides an all-solid state ion secondary battery in which a solid electrolyte layer is joined between a positive electrode active material layer and a negative electrode active material layer, characterized in that at least one of the positive electrode active material layer and the negative electrode active material layer is formed by binding active material particles and solid electrolyte particles together through an ion-conductive and ferroelectric substance. |
