Abstract
Disclosed is a method for producing an all-solid-state lithium ion secondary battery being excellent in cycle characteristics. The production method may be a method for producing an all-solid-state lithium ion secondary battery, wherein the method comprises an anode mixture forming step of obtaining an anode mixture by drying a raw material for an anode mixture, which contains an anode active material, a solid electrolyte and an electroconductive material; and wherein, for the anode mixture after being dried in the anode mixture forming step, a voidage V of the inside of the anode mixture calculated by the following formula (1) is 43% or more and 54% or less: V=100−(D1/D0)×100 Formula (1).
