NOVELTY - The battery incorporates a coil electrode formed by laminating elongated positive and negative electrodes through separators such that the outermost layer is the positive electrode. The negative lead is formed at the negative electrode at a position which is further forward than the outermost end of the positive electrode without a projection being formed which eliminates a possible source of shorting.    USE - Non-aqueous electrolyte secondary batteries.    ADVANTAGE - The battery has a reduced quantity of non-reacted active material for the negative electrode to more effectively use the volume of the battery to raise energy density, lengthen cycle life, prevent defects, and improve reliability.    DETAILED DESCRIPTION - The non-aqueous electrolyte secondary battery comprises a coil electrode formed by laminating an elongated positive electrode with a positive electrode mix layer on at least one main surface of a collector and an elongated negative electrode with a negative electrode mix on at least one main surface such that the positive electrode is on the outside of the coil.    The positive mix layer is formed only at the position adjacent the outermost end of the positive electrode and/or the position adjacent to the innermost end, and not formed on the collector at the outermost end of the electrode, and only the positive electrode collector is formed. The negative electrode mix is not formed on the collector at the outermost end of the negative electrode and only the negative collector is formed.The outermost end of the negative electrode collector is positioned at the outermost end of the electrode and is, in the direction from the inner to outer portion of the coil, positioned more forwards than the outermost end of the positive electrode collector.
