Abstract
The present invention relates to an ionically conductive polymeric gel electrolyte for batteries having high ionic conductivity and sufficiently high solid strength. The invention has an object to provide a solid battery which prevents internal short-circuiting even if no diaphragm is used and which has high reliability, by using the ionically conductive polymeric gel electrolyte. Disclosed is an ionically conductive polymeric gel electrolyte, containing at least a polymer matrix, a non-aqueous electrolytic solution and an electrolytic salt, wherein at least one kind of a halogen-substituted carbonic ester is contained as a solvent of the non-aqueous electrolytic solution. Also disclosed is a solid battery having the ionically conductive polymeric gel electrolyte as a constituent.
