Abstract: An organic electroluminescence (EL) device includes a charge generating layer including a charge generating material or a hole injection layer including a hole injection material, the charge generating material or the hole injection material including a 1,2-closo-carborane compound represented by the following Formula 1: wherein each Ar1 is independently a substituted or unsubstituted aryl group or a substituted or unsubstituted heteroaryl group.

Abstract: A liquid action substance battery having its external terminal welded after assembling the battery in which safety of the battery is enhanced by protecting an explosion-proof valve against being torn apart in the subsequent welding work of the external terminal even if the position of a negative pole action substance being press-bonded to the inner surface of the battery can is shifted and that substance is extruded to the bottom face of the battery can.

Abstract: A non-aqueous electrolyte secondary cell containing an electricity-generating element with at least a cathode, a separator and an anode and a non-aqueous electrolyte inside a cathode case, electrode units each consisting of the cathode and the anode opposite to each another via the separator laminated to form an electrode group, or an electrode unit in a sheet form consisting of the cathode and the anode opposite to each another via the separator wound to form an electrode group, or a sheet-shape cathode wrapped with the separator except for a part contacting at inner face of cathode case and a sheet-shaped anode set on the sheet-shaped cathode in a right angled position each other and bent alternately to form an electrode group, and the total sum of the areas of the opposing cathode and anode in the electrode group larger than the area of the opening of an insulating gasket in a sealed portion in the cathode case or than the area of an opening in a sealed plate in a sealed portion in the cathode case.
