    摘要： The disclosure describes a non-aqueous electrolyte battery with an improved cycle life. The non-aqueous electrolyte battery includes a positive electrode including a positive electrode layer, a negative electrode including a negative electrode layer, a separator disposed between the positive electrode and the negative electrode, and a non-aqueous electrolyte containing a lithium salt. The negative electrode layer may contain a negative electrode active material which can insert and release lithium ions at 0.4 V or more (V.S. Li/Li+). The lithium salt may contains LiPF6 with a concentration of less than 50% (including 0%). The non-aqueous electrolyte battery may meet the following two formulas: 1≦Q2/Q1 (I) and 1≦C/A≦2 (II), where Q1 represents a capacitance in a facing portion of the negative electrode, Q2 represents a capacitance in the facing portion of the positive electrode, A represents an area of a surface including the facing portion of the negative electrode of the negative electrode layer, and C represents an area of a surface including the facing portion of the positive electrode of the positive electrode layer.

    摘要： In a flat non-aqueous electrolyte secondary cell comprising an electricity-generating element including at least a cathode, a separator and an anode and a non-aqueous electrolyte in the inside of a cathode case, a plurality of electrode units each consisting of the cathode and the anode opposite to each another via the separator are 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 is wound to form an electrode group, or a sheet-shape cathode is wrapped with the separator except for a part contacting at inner face of cathode case and a sheet-shaped anode is set on the sheet-shaped cathode in a right angled position each other and then these cathode and anode are bent alternately to form an electrode group, and the total sum of the areas of the opposing cathode and anode in this electrode group is 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, whereby the discharge capacity upon heavy-loading discharge is significantly increased as compared with the conventional cells. Accordingly, while the size of the cell is small, the discharge capacity is increased as described above, and thus it is possible to provide a highly utilizable flat non-aqueous electrolyte secondary cell. Further, in said flat non-aqueous electrolyte secondary cell, problems which may be caused by the increased discharge capacity in the cell can be solved by improving the solvent and supporting electrolyte for the electrolyte or by various improvements in the cathode and anode cases.
