摘要： Conventional ion rechargeable batteries having an electrode layer on an electrolyte layer suffer from an impurity layer formed at the interface, degrading performance. Conventional batteries with no such impurity layer have a problem of weak interface bonding. In the present invention, in a baking process step after an electrode layer is laminated on an electrolyte layer, materials for an electrode layer and an electrolyte layer are selected such that an intermediate layer formed of a reaction product contributing to charging and discharging reactions is formed at the interface of the electrode layer and the electrolyte layer. In addition, a paste that an active material is mixed with a conductive material at a predetermined mixing ratio is used to form a positive electrode layer and a negative electrode layer. Reductions in electrode resistance and interface resistance and improvement of charging and discharging cycle characteristics are made possible.

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.
