Problems solved by technology

[0004] However, when a module including many small batteries is used as a high-capacity secondary battery, weight and cost increase
Furthermore, in high-capacity secondary batteries, the capacity per unit cell increases, which can significantly impair battery stability and increase the cost required to obtain the same level of performance

Abstract

Battery modules have a plurality of electrode assemblies in which the electrode tabs of electrode assemblies are easily attached to the battery cases by a common insulator including receptacles for receiving the electrode assemblies. These configurations enable easy manufacture of medium- and large-sized battery modules with a plurality of electrode assemblies. In some embodiments, a battery module includes an insulator capable of mounting a plurality of electrode assemblies and receptacles in the insulator for receiving a portion of each electrode assembly.

Description

technical field [0001] The present invention relates to a battery cell, and more particularly, to a battery cell including a plurality of electrode assemblies in which electrode tabs of the electrode assemblies can be easily attached to a battery case, thereby manufacturing medium-sized and large-sized battery modules. Background technique [0002] Unlike primary batteries, which cannot be repeatedly charged, secondary batteries can be repeatedly charged and discharged. Low-capacity secondary batteries with one cell are used in small, portable electronic devices such as cell phones, notebook computers, and camcorders. A high-capacity secondary battery including a plurality of battery cells connected in groups has attracted attention as a power source for driving a motor such as a hybrid electric car or the like. [0003] High-capacity secondary batteries connected in series with each other to drive a motor (for example, an electric vehicle, etc.) require high power and can ...
