NOVELTY - The battery has positive electrode sheet (64) that is equipped with positive electrode collector (62) and positive electrode compound material layer (66). The positive electrode active materials (68A,68B) are provided on both the ends (66A) and center portion (66B) of positive electrode compound material layer in winding axial direction. A DBP absorbed quantities (mL/100g) of one positive electrode active material is set smaller than the DBP absorbed quantities of other positive electrode active material based on JIS K6217-4.    USE - Non-aqueous-electrolyte secondary battery such as lithium ion secondary battery mounted on vehicle (claimed) such as motor vehicle, hybrid vehicle, electric vehicle and fuel cell electric vehicle. Can also be used magnesium ion battery used as power supply for personal computer, portable terminal and other electricity products.    ADVANTAGE - Since the both ends of the positive electrode compound material layer have the low impregnatability, the movement of the non-aqueous electrolyte in the winding axial direction can be effectively suppressed, such that the outflow of the non-aqueous electrolyte from the positive electrode compound material layer at the time of charging/discharging can be prevented and the impregnatability of the center portion of the positive electrode compound material layer can be improved. Thus the battery performance can be enhanced. Also the increase in internal resistance of the positive electrode by the non-aqueous electrolyte flowing out into the exterior of the positive electrode compound material layer can be suppressed.
