Abstract
Disclosed is a secondary battery, which can minimize occurrence of a short-circuit between a cap plate and an electrode assembly while maximizing the size of an electrolyte injection hole of an inner case. The secondary battery includes at least one electrode assembly, an insulating inner case accommodating the electrode assembly, an outer case accommodating the electrode assembly and the inner case, and a cap plate sealing an opening of the outer case, wherein the inner case has a top surface corresponding to the cap plate and an injection hole for electrolyte injection located in the top surface.
