Abstract: An inorganic nonaqueous electrolytic solution type cell comprising an oxyhalide which is in the liquid state at room temperature and serves as an active material for a positive electrode and as a solvent for an electrolytic solution; a negative electrode made of an alkali metal; a positive electrode made of a porous carbon molded article; and a separator which is positioned between said negative electrode and said positive electrode and comprises a nonwoven fabric of glass fibers and a microporous film having a substantially uniform micropores having curved passages, which cell suffers less decrease of closing voltage after storage and less formation of the internal short circuits due to vibration.

Abstract: An inorganic nonaqueous electrolytic solution type cell comprising a separator which is positioned between a negative electrode and a positive electrode, a bottom insulator which is positioned between a bottom of a cell container and a positive electrode, and an electrolytic solution comprising an electrolyte and an oxyhalide which is in the liquid state at room temperature and serves as an active material for a positive electrode and a solvent for the electrolytic solution, wherein each of the separator and the bottom insulator comprises a material selected from the group consisting of a microporous film of an ethylene-tetrafluoroethylene copolymer and a composite sheet of a microporous film of an ethylene-tetrafluoroethylene copolymer and a nonwoven glass fabric.

Abstract: A non-aqueous electrochemical cell comprising an anode containing an alkali metal as an essential component of the active anode material, a cathode collector comprising a carbonaceous porous shaped body and a cathode-electrolyte consisting of an ionically conductive solution of a solute in a solvent containing a liquid oxyhalide, characterized in that at least one of the electrolyte and the collector is incorporated with an aromatic compound to prevent voltage drop at the initial stage of discharge.
