    摘要: A multilayer whole solid-type lithium ion rechargeable battery has hitherto been produced by stacking green sheets of a positive electrode layer, a solid electrolyte layer, and a negative electrode layer, which are formed of respective materials different from each other in coefficient of thermal expansion, and firing the layers at a time. This technique poses problems of delamination and nonlamination attributable to a difference in shrinkage. The problems can be solved by forming green sheets with the addition of a sintering aid to each starting material powder for the positive electrode layer, the solid electrolyte layer, and the negative electrode layer and performing control, by setting the additive rate of the sintering aid and the firing temperature, so that the shrinkages of the respective green sheets are substantially equal to each other. Consequently, unfavorable phenomena such as delamination can be prevented.
