Abstract
A non-aqueous electrolyte secondary battery includes: a negative electrode active material represented by the Formula (1)=α (Si material)+β (carbon material), wherein the Si material is one or more kinds selected from the group consisting of SiOthat is a mixture of amorphous SiOparticles and Si particles and a Si-containing alloy; α and β represent % by mass of each component in the layer; and 80≤α+β≤98, 0.1≤α≤40, and 58≤β≤97.9 are satisfied, and a difference between the maximum value and the minimum value of an area proportion (%) of a binder in an area of the field of view of each image of cross-sections of the layer in a case where a plurality of arbitrary places is selected in a plane of the negative electrode active material layer is within 10%.
