<P>PROBLEM TO BE SOLVED: To improve the ion conductivity of an electrode film and a solid electrolyte film which are constituting members of an all-solid lithium secondary battery, and improve battery characteristics of the all-solid lithium secondary battery. <P>SOLUTION: There are provided the all-solid lithium secondary battery having the solid electrolyte film for the all-solid lithium secondary battery which contains lithium ion conductive material particles containing sulfur, phosphor, and lithium, has a film thickness of 10 to 300 μm in which the porosity is 30% or smaller, a positive electrode film for the all-solid lithium secondary battery containing positive electrode active substances, a negative electrode film for containing negative electrode active substances, and a forming method for these films. The all-solid lithium secondary battery has at least one of these films. <P>COPYRIGHT: (C)2009,JPO&INPIT |
