Abstract
The present invention provides a sol-gel composition which comprises a mixture of a polyalkylene glycol-substituted trialkoxysilane (PAGTAS), a polyalkylene glycol and/or alkyl ether, a tetraalkoxysilane (TAOS), a hydrochloric acid, at least one organic solvent and/or a lithium salt, which mixture is optionally concentrated; a polymeric ion conductive film obtained by coating said compositions with a conventional solution processing method and solid electrochemical elements using the same. According to the present invention, a polymeric ion conductive film having no phase separation, strong adhesiveness for electrode, and ion conductivity of at least 1.times.10.sup.-4 S/cm at room temperature is provided.
