1. A solid-state alkali ion battery comprising:
an anode comprising a silicon-containing active material;
a separator comprising an inorganic phase comprising an ionically conductive inorganic particles and an organic phase comprising a binder, wherein the binder is a non-ionically-conductive polymer having a number average molecular weight of at least 100 kg/mol, and wherein the binder is soluble in a non-polar organic solvent, wherein particle-to-particle contact between the ionically conductive inorganic particles provides ionically conductive pathways through the separator such that the separator has an ion conductivity of at least 1×10−4 S·cm.
