<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an all solid lithium secondary battery capable of obtaining the all solid lithium secondary battery having a high energy density and high reliability which can prevent a failure due to internal short circuit, even in the case the solid electrolyte layer is made thin. <P>SOLUTION: This is the manufacturing method of the all solid lithium secondary battery which has at least a metal foil as a negative electrode layer, a positive electrode layer, and a solid electrolyte layer that is interposed between the negative electrode layer and the positive electrode layer. The manufacturing method has a negative electrode integration press process in which a press forming is carried out to integrate the metal foil and the solid electrolyte layer using the metal foil having a smaller diameter than that of the solid electrolyte layer. <P>COPYRIGHT: (C)2009,JPO&INPIT |
