All-solid-state secondary battery, solid electrolyte composition and electrode sheet for batteries used in the same, and manufacturing method of electrode sheet for batteries and all-solid-state secondary battery

An all-solid-state secondary battery comprising:

• a positive electrode active substance layer;
• a negative electrode active substance layer;
• and
• an inorganic solid electrolyte layer,
• wherein at least one layer of the positive electrode active substance layer, the negative electrode active substance layer, or the inorganic solid electrolyte layer contains a nitrogen-containing polymer, which has at least two selected from the group consisting of a repeating unit having a substituent X, a repeating unit having a substituent Y and a repeating unit having a substituent Z described below and an inorganic solid electrolyte having conductivity of ions of metal belonging to Group 1 or 2 in the periodic table,
• X is a group containing a functional group having pKa of 14 or less,
• Y represents a group having a polymer chain including a hetero atom, and Y may be linked to another nitrogen-containing polymer molecule to form a linking chain, and
• Z represents a group having an alkyl group having 1 to 30 carbon atoms, a group having a halogenated alkyl group having 1 to 30 carbon atoms, or a group having a silicone chain having 1 to 100 silicon atoms.
