Abstract
A lithium secondary battery comprises an electrode assembly and a non-aqueous electrolyte. The electrode assembly is made by winding a negative electrode, a positive electrode, and a separator interposed between the negative and positive electrodes. The negative electrode contains a negative electrode active material that is alloyed with lithium. The non-aqueous electrolyte is impregnated in the electrode assembly. At least one of the negative and positive electrodes is divided into a plurality of electrode units which are arranged at spaces for each other along the winding direction.
