Abstract
An anode for a non-aqueous electrolyte secondary battery includes: an anode current collector; and an anode mixture layer formed on the anode current collector, containing an anode active material, a conductor, a rubber-based binder, and a water-soluble polymer-based binder. The anode mixture layer comprises, relative to a total weight thereof, 1.0-2.5 wt % of the rubber-based binder and 0.5-1.5 wt % of the water-soluble polymer based binder. When the anode mixture layer is divided into ten equal parts in the thickness direction based on the current collector, a ratio (C/C) at an interval of 0 to 3 of a content ratio (C) of the rubber-based binder to a total content of the rubber-based binder to a content ratio (C) of the water-soluble polymer-based binder to a total content of the water-soluble polymer-based binder is larger than 1.0, and a ratio (C/C) at an interval of 7 to 10 is smaller than 1.0.
