Abstract

The present invention discloses a secondary battery which includes an electrode assembly for generating electricity, a can for accommodating the electrode assembly, and a cap assembly. The can has an open top and the cap assembly seals the open top. The electrode assembly has a plurality of electrode tabs through which electricity is supplied. The cap assembly includes an insulating case that hasa plurality of tab drawing grooves. Each of the tab drawing grooves is capable of being occupied by one of the electrode tabs. A number of the tab drawing grooves is greater than a number of the electrode tabs. One of the electrode tabs can be drawn through one of the tab drawing grooves. Other tab drawing grooves are left as spare grooves, and therefore it is not necessary to change the shape ofthe insulating case even though the structure of the secondary battery is changed.

Description

technical field [0001] The invention relates to a secondary battery with an insulating case. The insulating case has grooves through which electrode tabs protruding from the electrode assembly may be drawn out. The insulating case has spare slots so that the insulating case can be used in various designs of secondary batteries. Background technique [0002] Rechargeable secondary batteries are less expensive than disposable dry batteries. In recent years, as secondary batteries that are small in size and high in capacity have been developed, they have been widely used as power sources for portable electronic / electrical devices such as cellular phones, camcorders, notebook computers, and the like. [0003] Secondary batteries include nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, and lithium secondary batteries. Among these secondary batteries, lithium secondary batteries are most widely used due to their small size, high capacity, high op...
