摘要： Provided is a titanic acid-based solid electrolyte material free from risk of production of hydrogen sulfide, free of rare earth, and having good electrochemical stability and lithium-ion conductivity. A titanic acid-based solid electrolyte material 1 is made of a titanate having a structure in which a plurality of host layers 2 are laid one on top of another, the host layer 2 being formed so that octahedra each formed of a titanium atom coordinated with six oxygen atoms are two-dimensionally chained while sharing ridges, and lithium ions 3 and divalent or higher-valent cations (α) 4 are intercalated in interlayers between the host layers 2, titanium sites in the host layers 2 being partially substituted by monovalent to trivalent cations (β).

摘要： To provide an electrolytic solution that suppresses increase in the OH− ion concentration even in the case of electrochemical changes and thereby reduces deterioration or corrosion of resin, rubber, or metal to improve the reliability of an electrochemical device, an electrolyte used in the electrolytic solution, and an electrochemical device comprising the electrolytic solution. The electrolyte, for example, comprises a compound having a cation unit represented by the following formula and an electrolyte (a quaternary ammonium salt or the like). (In the formula, R1, R2, R3, and R4 are the same or different and each represent an alkyl group or an alkoxyalkyl group; R1 and R2 may together form a ring such as a pyrrolidine ring and a piperidine ring; and R3 and R4 may together form a ring such as a pyrrolidine ring and a piperidine ring.)
