<P>PROBLEM TO BE SOLVED: To provide an all-solid battery for charge and discharge operation even with all solid by expanding an interface area where an electrode active material and an all-solid electrolyte are jointed and by lowering the interface reaction resistance. <P>SOLUTION: The all-solid battery includes a solid electrolyte calcined body 14, a first electrode layer 18 (for example, a positive electrode) which is formed by calcining and integrating on one face of the solid electrolyte calcined body 14 and by mixing and heating calcination of an electrode active material 16 and the solid electrolyte 12, and a second electrode layer 20 (for example, a negative electrode) which is formed by calcining and integrating on the other face of the solid electrolyte calcined body 14 and by mixing and heating calcination of the electrode active material 16 and the solid electrolyte 12. The first electrode layer 18 and the second electrode layer 20 are made by mixing and heating calcination of an amorphous solid electrolyte and the electrode active material which have relations of Ty>Tz, when the temperature at which the capacity of the electrode active material is reduced by reaction of the solid electrolyte material and the electrode active material is made Ty, and the temperature at which the solid electrolyte material shrinks by calcination is made Tz. <P>COPYRIGHT: (C)2009,JPO&INPIT |
