    摘要: The objective of the present invention is to prevent deterioration and expanding of anode active material and to improve charge-discharge cycle characteristics in a non-aqueous electrolyte secondary battery comprising an anode of which current collector has thereon a thin layer of an anode active material containing a metal. To solve this problem, in a non-aqueous electrolyte secondary battery wherein a thin layer of anode active material containing a metal which absorbs and discharges lithium is formed on a current collector and the thin layer of the anode active material is divided into columns by a gap formed along the thickness thereof, a compound represented by the following formula is contained in the non-aqueous electrolyte. A-N═C═O In the above formula, A represents an element or a group other than hydrogen.
