ABSTRACT:
A nonaqueous-electrolyte secondary battery including a coil electrode formed by laminating an elongated positive electrode having a positive-electrode-mix layer formed on at least one surface of a positive-electrode collector and an elongated negative electrode having a negative-electrode-mix layer formed on at least one surface of a negative-electrode collector and by winding a laminate such that the positive electrode is positioned at the outermost position, wherein the positive-electrode-mix layer is formed on only one surface of the collector at the position adjacent to the outermost end of the positive electrode and/or the position adjacent to the innermost end of the positive electrode. The positive-electrode-mix layer is not formed on the positive-electrode collector at the outermost end of the positive electrode. The negative-electrode-mix layer is not formed on the negative-electrode collector at the outermost end of the negative electrode and the outermost end of the negative-electrode collector positioned at the outermost end of the negative electrode is, in the direction from the inner portion of the coil electrode toward the outer portion, positioned more forwards than the outermost end of the positive-electrode collector.
