Abstract

A rechargeable battery includes: an electrode assembly including a first electrode, a second electrode, and a separator between the first electrode and the second electrode; a case including an inner space accommodating the electrode assembly, and an opening; a cap plate coupled to the case at the opening and including a terminal hole exposing the inner space; an electrode terminal electrically connected to the electrode assembly through the terminal hole and overlapping the cap plate; electrode tabs respectively connected to the first electrode and the second electrode; and an electrolyte solution in the inner space, and at least one electrode tab of the electrode tabs has an inclined portion that is inclined at a first angle with respect to a surface of the electrode assembly facing the at least one electrode tab.

Description

technical field [0001] Aspects of embodiments of the invention relate to a rechargeable battery. Background technique [0002] Rechargeable batteries differ from primary batteries in that rechargeable batteries can be repeatedly charged and discharged whereas primary batteries cannot be recharged. Low-capacity rechargeable batteries are used in portable electronic devices such as mobile phones, notebook computers, and camcorders, and large-capacity rechargeable batteries are widely used as power sources for driving motors of hybrid vehicles and the like. [0003] As typical rechargeable batteries, there are nickel-cadmium (Ni-Cd) batteries, nickel-metal hydride (Ni-MH) batteries, lithium (Li) batteries, lithium-ion (Li-ion) rechargeable batteries, and the like. In particular, Li-ion rechargeable batteries have operating voltages three times higher than those of Ni-Cd batteries and Ni-MH batteries, which are widely used as power sources for portable electronic devices. In a...
