PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte battery that has an excellent stability even when the battery has fallen in an unforeseen state of short- circuiting by being used in such an abnormal condition as causes deformation in the electrode. SOLUTION: The battery comprises a positive electrode having plural layers of positive electrode active material layers 2 containing positive electrode active material on the positive electrode current collector 1, a negative electrode containing negative electrode active material and a non-aqueous electrolyte. The composition of the positive electrode active material contained in the positive electrode active material layers 2 is different in the thickness direction of the layers. |
