<P>PROBLEM TO BE SOLVED: To provide an all-solid battery capable of being easily caulked, allowing pressure to be evenly applied to the whole surface of a solid electrolyte layer, capable of suppressing the swell of the battery in its central part, and of keeping a battery characteristic against repeated charge and discharge, and high in ion conductivity. <P>SOLUTION: This all-solid battery 1 having an all-solid battery element formed by interposing the solid electrolyte layer 5 between a positive electrode 3 and a negative electrode 6 is provided support plates 7 each having a plurality of through-holes 8 on the respective sides of the positive electrode and the negative electrode without facing the solid electrolyte layer. The all-solid battery is characterized in that pressure of 1.5-200 MPa is applied to the all-solid battery element by connecting/fastening the support plates through the corresponding through-holes of the respective support plates; and at least one of the through-holes is located in a circle of 1/4 of the total area from the central part of the support plate toward the edge thereof. <P>COPYRIGHT: (C)2008,JPO&INPIT |
