Claim 0:
1. A solid electrolyte composition comprising:
an inorganic solid electrolyte having conductivity for ions of metal elements belonging to Group I or II of the periodic table;
binder particles which include a polymer having an SP value of 11 cal1/2 cm−3/2 or more and have an average particle diameter of 10 nm or more and 50,000 nm or less, wherein the SP value of the polymer is a value that is computed from the SP values of individual repeating units obtained using the Hoy method; and
a dispersion medium,
wherein the mass-average molecular weight of the polymer forming the binder particles is 5,000 or more, and
the polymer is an acrylic resin and said acrylic resin includes a repeating unit of at least one of monomers represented by the following Formulae (a-1) to (a-3) and (a-7),, wherein the acrylic resin including a repeating unit of a monomer represented by the Formula (a-1) has the repeating unit of a monomer represented by the Formula (a-1) in its main chain and a repeating unit of a macromonomer having a mass-average molecular weight of 1,000 or more and 500,000 or less as the side chain component, said macromonomer containing a repeating unit of a (meth)acrylic acid ester monomer,
in the Formula (a-1), R11 represents a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, or an aryl group, X represents O or >NH, L11 represents a single bond or an unsubstituted alkylene group having 1 to 3 carbon atoms, and R12 represents a hydrogen atom, an unsubstituted alkyl group having 1 to 6 carbon atoms, or a hydroxyl group (—OH),
in the Formulae (a-2), (a-3) and (a-7), L11 represents a single bond or a linking group that is selected from a group consisting of a hydrocarbon linking group selected from a group consisting of an alkylene group having 1 to 10 carbon atoms, an alkenylene group having 2 to 10 carbon atoms, an alkynylene groups having 2 to 10 carbon atoms, an arylene groups having 6 to 22 carbon atoms, and a combination thereof; a hetero linking group selected from a group consisting of a carbonyl group (—CO—), a thiolcarbonyl group (—CS—), a thioether group (—S—), an imino group (—NRN—), an ammonium linking group (—NRN2+—), a polysulfide group having 1 to 8 sulfur atoms, an imine linking group (RN—N═C<, —N═C(RN)—), a sulfonyl group (—SO2—), a sulfinyl group (—SO—), a phosphoric acid linking group (—O—P(OH)(O)—O—), a phosphonic acid linking group (—P(OH)(O)—O—), and a combination thereof, wherein RN has the same meaning as R12; and a linking group made of a combination thereof, X represents —O— or >NH, R11 represents a hydrogen atom, a hydroxy group, a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, or an aryl group, R12 represents a hydrogen atom or a substituent, R13 represents a hydrogen atom, an alkyl group, a hydroxy group-containing group, or a carboxy group-containing group and R13 may be the linking group of L11 and constitute a dimer at this portion, and R15 and R16 each independently represent a substituent.
