An all-solid battery includes: a positive electrode active material layer (1) that includes a positive electrode active material (4); a negative electrode active material layer (2) that includes a negative electrode active material; and a solid electrolyte layer (3) that is formed between the positive electrode active material layer (1) and the negative electrode active material layer (2). The positive electrode active material layer (1) or the solid electrolyte layer (3) further includes a solid electrolyte material (5). A reaction suppressing portion (6) is formed at an interface between the positive electrode active material (4) and the solid electrolyte material (5). The reaction' suppressing portion (6) is a chemical compound that includes a cation portion formed of a metal element and a polyanion portion formed of a central element that forms covalent bonds with a plurality of oxygen elements.

La batterie totalement solide selon l'invention comprend : une couche de matériau actif délectrode positive (1) qui comprend un matériau actif délectrode positive (4); une couche de matériau actif délectrode négative (2) qui comprend un matériau actif délectrode négative; et une couche délectrolyte solide (3) qui est formée entre la couche de matériau actif délectrode positive (1) et la couche de matériau actif délectrode négative (2). La couche de matériau actif délectrode positive (1) ou la couche délectrolyte solide (3) comprend en outre un matériau délectrolyte solide (5). Une partie supprimant la réaction (6) est formée à une interface entre le matériau actif délectrode positive (4) et le matériau délectrolyte solide (5). La partie supprimant la réaction (6) est un composé chimique qui comprend une partie cationique formée dun élément métallique et une partie polyanionique formée dun élément central qui forme des liaisons covalentes avec une pluralité déléments oxygène.
