Title: SECONDARY BATTERY HAVING STEPPED CELL STRUCTURE
Abstract:
The present invention relates to a secondary battery having a stepped cell structure and, more particularly, to a secondary battery having a stepped cell structure, which is configured to maximally utilize a storage space inside an electronic device in which a secondary battery is accommodated. A plurality of electrode assemblies having different sizes are accumulated in multiple stages, and can be accommodated in a secondary battery storage space of an electronic device having a curved surface type space in the form of a curve, or in a secondary battery storage space of an electronic device having an uneven portion due to a height difference according to the arrangement of electronic components. Thus, it is possible to maximally utilize a secondary battery storage space inside an electronic device. Also, since the remaining space of the secondary battery storage space of an electronic device of the present invention is maximally utilized, it is possible to increase the capacity and usage time of a battery.
