Abstract
A lithium rechargeable battery includes an electrode assembly having a first electrode, a second electrode, and a separator interposed between them, a can having an opening to contain the electrode assembly, and a cap plate coupled to the top of the can. A side of the can is asymmetrical with respect to another side thereof about at least one of a long axis, short axis, and central point of its cross section. The lithium rechargeable battery has a predetermined space formed between the can and the electrode assembly for improved electrolyte injection and increased manufacturing efficiency and power storage capacity of the battery.
