  "textContent": "An object of the present invention is to further improve charge-discharge cycle performance in a lithium secondary battery using a negative electrode active material that is alloyed with lithium. A lithium secondary battery 1 comprises an electrode assembly 10 and a non-aqueous electrolyte. The electrode assembly 10 is made by winding a negative electrode 11, a positive electrode 12, and a separator 13 interposed between the negative and positive electrodes 11, 12. The negative electrode 11 contains a negative electrode active material that is alloyed with lithium. The non-aqueous electrolyte is impregnated in the electrode assembly 10. At least one of the negative and positive electrodes 11, 12 is divided into a plurality of electrode units 11A, 11B which are arranged at spaces for each other along the winding direction.",
