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, a value obtained by dividing a volume percentage (%) of the electroconductive material when the volume of the anode mixture is determined as 100 volume %, by a voidage V (%) of the inside of the anode mixture calculated by the following formula (1), is 2.3 or more and 16.2 or less: V =100−( D 1 /D 0 )×100   Formula (1)

Claim (Index 1):
A method for producing an all-solid-state lithium ion secondary battery comprising a cathode, an anode and a solid electrolyte layer disposed therebetween,\n 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 an electricity passing step of passing electricity through a laminate comprising a cathode mixture, the anode mixture and a solid electrolyte material part disposed between the electrode mixtures to change the cathode mixture, the anode mixture and the solid electrolyte material part into a cathode, an anode and a solid electrolyte layer, respectively; wherein the anode active material comprises at least one active material selected from the group consisting of a metal that is able to form an alloy with Li and an oxide of the metal; and wherein, for the anode mixture after being dried in the anode mixture forming step, a value obtained by dividing a volume percentage (%) of the electroconductive material when the volume of the anode mixture is determined as 100 volume %, by a voidage V (%) of the inside of the anode mixture calculated by the following formula (1), is 2.3 or more and 16.2 or less:\n V= 100\u2212( D 1 /D 0 )\u00d7100 \u2003\u2003Formula (1) \n (where V is the voidage (%) of the inside of the dried anode mixture; D 1  is an absolute density (g/cm 3 ) of the anode mixture; and D 0  is a true density (g/cm 3 ) of the anode mixture.)
